5. SPECIFICATIONS
5.1 Introduction
The zipSTOP Brake assembly is a controlled braking force device designed specifically for use in the zip line
industry as a Primary or EAD at the end of zip line runs. The zipSTOP caters to a range of rider weights and
approach speeds, and oers a smooth, consistent braking force for all riders. The brake is designed to be
mounted to a primary and/or secondary anchor point to slow the decent of riders on a zip line. The primary
anchor point is exactly what it sounds like; it is the main attachment point for the brake. The secondary anchor point is the support point for the redirection lines and pulleys.
The zipSTOP Brake Unit is installed at the end of the zip line, usually on or adjacent to the terminal end. A
Secondary Anchor Point is normally required upstream of the landing area to provide support for the Redirection Line pulleys. Alternately a full-length secondary cable of sucient capacity can be installed to provide
support for the Redirection Line and associated pulleys.
The design of the zipSTOP allows for simple installation, and incorporates both an advanced self-regulating
brake unit and an automatic line reset. The patented braking mechanism delivers smooth deceleration and
is designed to minimize variations in the deceleration rate and stopping distance of both children and adults.
There are no friction parts in the brake mechanism, ensuring reliability remains high while maintenance and
operating costs are kept to a minimum.
Installation, inspection, operation and maintenance must be carried out in accordance with the instructions in
this manual to protect the longevity of the zipSTOP components.
Pictures in this manual are for reference purposes in terms of geometry and proposed redirection setup
configuration only. Mandated EAD may or may not be shown.

6. OPERATING PRINCIPLES
6.1 General
The zipSTOP Brake assembly is a controlled braking force device designed specifically for use as a Primary or
EAD at the end of zip line runs. The zipSTOP caters to a range of rider weights and approach speeds and oers
a smooth, consistent braking force for all riders. zipSTOP Brake performance relies on operators using the
correct equipment and operating the system in accordance with the instructions contained within this manual.
The zipSTOP Brake assembly consists of a zipSTOP Brake Unit, zipSTOP Brake Trolley, redirection pulleys and
associated Redirection Lines.

Rest Position
The zipSTOP Brake Unit is located at the zip line terminal end, normally adjacent to the landing area. It is
connected via a redirection pulley and Redirection Line setup to the zipSTOP Brake Trolley.
The Brake Trolley is located on the zip line and when idle (zipSTOP Braking Line fully retracted) will be
positioned at the start of the rider Arrest Zone (Reset Position). The approaching rider trolley contacts
the Brake Trolley, moving it down the zip line. As the Brake Trolley moves into the Arrest Zone it extends
the Braking Line out of the zipSTOP Brake Unit via the Redirection Line. As the Braking Line extends out
of the zipSTOP Brake Unit, the eddy current brake in the unit is activated, controlling the rate of deceleration and slowing the rider in a smooth manner.
Once the load is removed from the Brake Trolley, the return mechanism in the zipSTOP Brake Unit
retracts the Braking Line, automatically returning the Brake Trolley to the start of the Arrest Zone (Reset
Position) on the zip line, ready for the next rider.
When higher Redirection Ratios are employed retraction force is reduced and a manual reset of the Brake
Trolley may be necessary.
Ensure brake is reset before rider starts down zip line, every time.

7.9 Redirection Line
The Redirection Line is required to connect the zipSTOP Brake Unit to the Brake Trolley and will transfer the
braking force from the Brake Unit. The Redirection Line passes through the redirection pulleys and must meet
minimum specification. The following list provides several Redirection line options.
Head Rush Technologies developed the Gorilla Rope specifically for use as a redirection line with the zipSTOP
Zip Line Brake It features a high strength-to-weight ratio, is designed to be highly resistant to abrasion, UV
resistant, and water repellent. The 6mm Gorilla Rope maximizes performance because it is lighter, smaller in
diameter, minimizes resistance, and maximizes reliable reset.
Spectra - Spectra/Dyneema is one of the recommended materials because it has sucient strength while
minimizing size and diameter. Spectra/Dyneema is known for high strength and superior abrasion, water, and
UV resistance. The spectra line should be jacketed with an abrasion-resistant, temperature-tolerant material
to avoid possible degradation of the line due to friction. Gorilla Rope, a Head Rush Technologies product, is
designed specifically to provide high strength, a long life span, and minimal stretch for applications where a
small diameter rope is necessary. It is made for maximum durability and high performance in any application.
It is perfect for use as a reduction line with the zipSTOP Zip Line Brake but can also be used for many other
industrial or recreational applications where these qualities are critical.
Technora® - Technora, while the strongest of the synthetic fibers, is particularly sensitive to UV wear. Only
Technora core lines with UV protective jackets should be used. Technora lines are also slightly stier which
can increase retraction drag when used as a Redirection Line. The drag is usually oset by the fact that a
smaller diameter Technora line can be employed compared to another material.
Nylon and Other materials - Nylon or other materials can be used provided they meet the minimum requirements for strength, UV, and wear resistance. However, these lines may necessitate much larger diameter ropes
to attain the necessary strength which can have an adverse eect on Redirection Line performance.

ALWAYS USE THE SPECIFIED REDIRECTION LINE
Failure to utilize a Redirection Line of specified strength and quality can compromise zipSTOP brake operation, resulting in equipment damage, serious injury or death.
REDIRECTION LINE WILL BE SUBJECT TO WEAR AND ABRASION
Any Redirection Line selected for use will wear and must be replaced from time to time. Lines must be carefully inspected prior to use each day, and failure to do so may result in serious injury or death.
When selecting a Redirection line, the following considerations apply:
The line must meet the specifications described above. A lighter, smaller diameter line is preferred, to minimize resistance and weight, and maximize reliable
reset.
A waterproof line is required. Water absorption can add significant weight, allowing the line to sag
which increases the likelihood of incomplete reset for Brake Unit and Brake Trolley.

8. zipSTOP BRAKE ASSEMBLY CONFIGURATION
8.1 General
The zipSTOP Brake assembly is designed to be utilized as part of a complete zip line braking system, and can
be used for a wide range of zip line installations. The zipSTOP Brake assembly is suitable for use in both existing and new zip line installations.
Setup information contained within this manual relates only to the zipSTOP Brake assembly – The design,
installation and set-up of other components comprising the complete braking system are the responsibility of
the installer and/or operator.
COMPATIBILITY TESTING IS THE RESPONSIBILITY OF THE INSTALLER OR OPERATOR
The zipSTOP Brake is designed to work with most pulleys and zip lines but may not work with all. Compatibility is to be determined by the installer or operator based on experience and unmanned testing.
ALWAYS CARRY OUT UNMANNED TESTING TO DETERMINE ACTUAL BRAKING DISTANCE
The information contained in this manual is intended for guidance only. Calculated braking distances for
the zipSTOP Brake assembly are estimates only and may dier from actual braking distances achieved on
individual zip lines.
As there are infinite possibilities regarding participant weights and arrival speeds, line slopes and environmental
conditions, a safe and functional installation can only be achieved after careful consideration and unmanned
testing of all factors in advance of the zipSTOP installation.
The zipSTOP Brake is required to use both primary and emergency arrest devices functioning together to
arrest the motion of passengers. The EAD must engage with no input from the passenger upon failure of the
primary arrest device, and all required Confirmation and Warranty registration forms must be filled out and
returned; failure to do so may void your warranty (see Sections “Emergency Arrest Device (EAD) Confirmation”
and “Warranty Registration Form” respectively).
Pictures in this manual are for reference purposes in terms of geometry and proposed redirection setup
configuration only. Mandated EAD may or may not be shown.
8.2 Setup Variables, ZS125-08/ZSIR150-20A
A number of variables will influence the final braking distance and level of rider comfort, these include:
Rider arrival speed
Rider weight
Redirection Line Ratio (Only a 1:1 Applies with the ZSIR150-20A)
Rider arrival speed is unique to each zip line installation and is a factor of line slope, zip line length, rider
weight, rider descent position, wind and friction. It is necessary to know the acceptable minimum and maximum rider velocities prior to configuring the zipSTOP.
8.4 Rider Weight
Suitable rider weight ranges will need to be determined by individual zip line operators. The zipSTOP Brake
unit will accommodate riders between 15 and 150 kg (33 and 330 lbs). It is necessary to know the acceptable
rider weight range before configuring the zipSTOP.
8.5 Redirection Line Ratio
The Redirection Ratio is the most influential factor in the braking characteristics of the zipSTOP. The Redirection Ratio is the ratio between the Brake Trolley travel and the zipSTOP Braking Line extension.
The Redirection Ratio is achieved by passing the Redirection Line around a series of pulleys. This alters the
ratio of Brake Trolley travel to Braking Line extension, allowing the installer to tailor the braking distances and
deceleration rates, accommodating a wide range of arrival speeds and rider weights.
ZSIR15020A THIS PRODUCT CAN ONLY BE USED WITH 1:1 REDIRECTION SETUPS
The zipSTOP IR (ZSIR150-20A) is NOT compatible with external redirection setups in any way. Installing
a redirection setup with the zipSTOP IR can create a very dangerous set of braking conditions that could
result in abnormally abrupt late braking.
Various Redirection Ratios are possible:
1:1 Ratio
MUST be used for model ZSIR150-20A
Can be used for model ZS125-08
2:1 Ratio
Can be used for model ZS125-08 only
CANNOT be used for model ZSIR150-20A
3:1 and higher ratios – contact your zipSTOP Distributor, model ZS125-08 only
The recommended configuration orients all elements (zipSTOP Brake Unit, Redirection Pulleys, Brake Trolley)
in the vertical plane.
When higher Redirection Ratios (3:1 and higher) are employed (for model ZS125-08 only), retraction force is
reduced and a manual reset of the Brake Trolley will be necessary.
ALWAYS USE THE SPECIFIED REDIRECTION LINE
Failure to utilize a Redirection Line of specified strength and quality can compromise zipSTOP brake operation, resulting in equipment damage, serious injury or death.

REDIRECTION LINE WILL BE SUBJECT TO WEAR AND ABRASION
Any Redirection Line selected for use will wear and must be replaced from time to time. Lines must be carefully inspected prior to use each day, and failure to do so may result in serious injury or death.
8.5.1 1:1 RATIO
Attach zipSTOP braking line to redirection

Overhead Line
Zip Line
Brake Trolley
The 1:1 Redirection Ratio directly connects the zipSTOP Brake Unit to the zipSTOP Brake Trolley via a single
Type I Redirection Pulley. For every unit of Brake Trolley travel, the Braking Line extends an equal distance.
Characteristics of the 1:1 ratio are:
Suitable for low speeds
Strongest braking force
Short braking distances
Higher rate of rider deceleration
Maximum rider approach speed of 36 km/h (22 mph) – model ZS125-08
Maximum rider approach speed of 60 km/h (37 mph) – model ZSIR150-20A
In the case of the model ZS125-08: A 1:1 Redirection Ratio is used for zip line installations where low arrival
speeds are common. Although suitable for speeds up to 36 km/h (22 mph), typically a 1:1 ratio would be employed when approach speeds are less than 20 km/h (12 mph).

Overhead Cable – 2:1 Redirection Ratio
The 2:1 Redirection Ratio connects the zipSTOP Brake Unit to the zipSTOP Brake Trolley via both Type I and Type
II pulleys. With a 2:1 ratio the Brake Trolley travels twice the distance that the zipSTOP Braking Line extends.
Characteristics of the 2:1 ratio are:
Suitable for medium to high speeds
Optimal combination of stopping distance, braking force and reliability in reset
Optimum rider comfort
Longer braking distances than a 1:1 setup
Overhead support line (redirection point) recommended
Maximum approach speed of 60 km/h (36 mph)
A 2:1 Ratio is used on zip line installations where medium to high approach speeds are common but a soft
stop for the rider is desired. Although suitable for approach speeds up to 60 km/h (36 mph), typically a 2:1
ratio is employed when approach speeds are less than 40 km/h (24 mph).
A 2:1 Ratio is specifically PROHIBITED in any installation of the ZSIR150-20A. Utilizing an external redirection
will lead to potentially dangerous and harmful braking dynamics.
ZSIR15020A THIS PRODUCT CAN ONLY BE USED WITH 1:1 REDIRECTION SETUPS
The zipSTOP IR (ZSIR150-20A) is NOT compatible with external redirection setups in any way. Installing
a redirection setup with the zipSTOP IR can create a very dangerous set of braking conditions that could
result in abnormally abrupt late braking.

8.6 Possible Configurations (Informative Only)
8.6.1 3:1 RATIO
3:1 installation formats are a unique situation and the following information should be used to develop an
appropriate site plan.
The 3:1 ratio connects the zipSTOP unit to the braking trolley via redirection pulleys and supplementary line.
With a 3:1 ratio the braking trolley travels three meters for every meter of zipSTOP line. This will result in a longer stopping distance for the rider.
Characteristics of 3:1 ratio setup are:
Max. Approach Speed = 72 km/h.
Suitable for high arrival speed.
Softer stopping force from higher speeds
Longer stopping distances
More complex set-up.
A 3:1 ratio is commonly used on zip lines with high arrival speeds and when a longer braking distance is available. The 3:1 ratio is suitable for approach speeds up to 72 km/h (45 mph) allowing a softer stop after thrilling
high speed runs.

8.6.2 OTHER CONFIGURATIONS
The zipSTOP Brake assembly may be used with other zip line configurations and higher rider velocities. Configurations shown are based on a single line zip line. Dual zip lines and side-by-side configurations may also
be accommodated. Please contact your zipSTOP Distributor for information on alternate set-ups.
When higher Redirection Ratios (3:1 and higher) are employed (for model ZS125-08 only), retraction force is
reduced and a manual reset of the Brake Trolley will be necessary.
Pictures in this manual are for reference purposes in terms of geometry and proposed redirection setup
configuration only. Mandated EAD may or may not be shown.
Some examples of alternative configurations are shown below:
Beam Mounted Pulley - 2:1 Redirection Ratio
8.7 Zip Line Slope
Three zip line configurations at the end of the line are possible: flat line, positive line slope and a negative line
slope. The slope of the line will influence the braking distances as well as allowing the rider to roll slowly up or
down the line once decelerated.
www.headrushtech.com | +1-720-565-6885
Oset Redirection Pulley – 1:1 Redirection Ratio
NOTE: Oset redirection pulleys should only be used with highly
tensioned zip lines. Slack zip lines may cause binding and excessive
wear on the brake trolley.

8.10 Calculating zipSTOP Braking Distances
To calculate braking distances for the zipSTOP Brake assembly, follow the steps in the ‘Configuration Worksheet’ using the information contained in the ‘Braking Distance Charts’. Refer to Section “Appendix A: EAD
Warranty/Registration Form”.
ALWAYS CARRY OUT UNMANNED TESTING TO DETERMINE ACTUAL BRAKING DISTANCE
The information contained in this manual is intended for guidance only. Calculated braking distances for the zipSTOP Brake assembly are estimates only and may dier from actual braking distances achieved on individual
zip lines.
Exceeding maximum recommended line speed can cause injury to participants and damage equipment.
Before starting the zipSTOP configuration you will need to determine the rider weight range, rider arrival speed
range and preferred Redirection Ratio for the zipSTOP installation.
Information required for calculating zipSTOP braking distances:
Rider weight range
Arrival speed range
zipSTOP Redirection Line ratio
A number of other variables will aect the final performance of zipSTOP and must be taken into consideration
when designing the complete zip line braking system. These include, but are not limited to:
BRAKING DISTANCEDistance required to decelerate a rider.
BDMAX = MAXIMUM BRAKING DISTANCE
BDMIN = MINIMUM BRAKING DISTANCE
NOTE: Configurations that result in Braking distances that fall below the ‘BDmin’ line shown on the
chart are not recommended. These short braking distances may be uncomfortable for the rider and
may result in severe swinging up of rider when decelerating.

8.11 zipSTOP Braking Distance Charts
Charts for calculating braking distances are located at the back of this manual. These charts are to be used in
conjunction with the zipSTOP configuration worksheet to optimize the zipSTOP installation. Ensure that you
are using the correct chart for your zipSTOP model.
ALWAYS CARRY OUT UNMANNED TESTING TO DETERMINE ACTUAL BRAKING DISTANCE
The information contained in this manual is intended for guidance only. Calculated braking distances for the zipSTOP Brake assembly are estimates only and may dier from actual braking distances achieved on individual zip
lines. Exceeding maximum recommended line speed can cause injury to participants and damage equipment.
8.12 Configuration Notes
1. BDMIN LINE: BDmin line indicates the rate of deceleration that may be considered uncomfortable
and result in severe rider swing up when stopping. It is not recommended to operate the zipSTOP with
combinations of rider weights and arrival speeds that fall below the BDmin line. Operating below the
BDmin line runs the risk of rider swinging up and contacting the zip cable.
www.headrushtech.com | +1-720-565-6885
31
Page 31
2. LINE EXTENSION (LEX) – Line extension is the distance the Braking Line extends out of the zipSTOP
brake Unit. If LEX is greater than 12.0m then reduce maximum permissible approach speed (ASmax),
permissible rider weight (RWmax) or increase Redirection Ratio (RR). Exceeding 12m runs the risk of an
abrupt stop when the webbing reaches its termination as well as damage to the zipSTOP, webbing and
other equipment.
3. BUFFER ZONE (BZ) – Buer zone is the area after the Arrest Zone in which riders are safe from impacting the terminal end or any other object in the event they overshoot the landing zone. The buer zone
must include the maximum distance required for the EAD to arrest a wayward rider.

9. zipSTOP BRAKE ASSEMBLY INSTALLATION
9.1 General
Simply put, the zipSTOP Brake is designed to be mounted to a primary anchor point to slow the decent of
riders on a zip line. The primary anchor point is exactly what it sounds like; it is the main attachment point for
the brake. The secondary anchor point is the support point for the redirection lines and pulleys.
The zipSTOP Brake Unit is installed at the end of the zip line, usually on or adjacent to the terminal end. A
Secondary Anchor Point is normally required upstream of the landing area to provide support for the Redirection Line pulleys AND forces associated with braking. Alternately a full-length secondary cable of sucient
capacity can be installed to provide support for the Redirection Line and associated pulleys.
Pictures in this manual are for reference purposes in terms of geometry and proposed redirection setup
configuration only. Mandated EAD may or may not be shown.
9.2 Safety Precautions
ALWAYS INSTALL AN EMERGENCY ARREST DEVICE EAD
An independent arrest device is required to safely stop riders in the event of operator error or third party
equipment failure.
PROPER DESIGN AND TESTING OF THE COMPLETE BRAKING SYSTEM IS ALWAYS REQUIRED
The complete brake system for zip Lines consists of all brakes employed, including primary brake and EAD.
All braking installations that include the zipSTOP as a component of the braking system must be designed,
tested and operated according to this Installation, Operation and Maintenance Manual and proper industry
and engineering practices. Failure to do so may result in serious injury or death to participants.
Exceeding maximum recommended line speed can cause injury to participants and damage equipment.
FAILURE TO CORRECTLY INSTALL OR MAINTAIN A ZIPSTOP BRAKE ASSEMBLY MAY RESULT IN
SERIOUS INJURY OR DEATH TO PARTICIPANTS.
ALWAYS CARRY OUT UNMANNED TESTING TO DETERMINE ACTUAL BRAKING DISTANCE
The information contained in this manual is intended for guidance only. Calculated braking distances for
the zipSTOP Brake assembly are estimates only and may dier from actual braking distances achieved on
individual zip lines.
AVOID CONTACT BETWEEN RIDER AND RIDER TROLLEY AND/OR BRAKE TROLLEY
Serious injury may result if rider contacts the rider trolley or Brake Trolley during the braking phase. Always
design zipSTOP Brake assembly installation to ensure rider cannot make contact with, or have any part of
their body caught between, the rider trolley and Brake Trolley.
34
www.headrushtech.com | +1-720-565-6885
Page 34
ENSURE ALL CABLES, ATTACHMENT LINES AND PULLEYS ARE CORRECTLY ATTACHED AND
MAINTAINED TO PREVENT TANGLING, SNAGGING, BINDING AND ABRASION.
Ensure that the Redirection Line is routed cleanly and in line through the pulley system, to prevent contact
with any surface other than the pulley sheaves.
ALL STRUCTURES, SUPPORTS AND ANCHORS MUST BE EVALUATED AND DESIGNED AC
CORDING TO PROPER INDUSTRY AND ENGINEERING PRACTICES. QUESTIONS ABOUT
STRUCTURES, SUPPORTS AND ANCHORS SHOULD BE REFERRED TO YOUR ZIP LINE’S ENGI
NEER.
The act of decelerating a rider at the termination of a zip line can generate extreme loads.
9.3 Primary Anchor Point
The Primary Anchor Point provides support for the zipSTOP Brake Unit. The anchor point and associated
fittings must be of sucient strength and form to provide a secure mount and to support all applied loads
sustained during zip line operation.
Loads specified are for the zipSTOP Brake assembly installation only and do not allow for any additional equipment or other loadings applied to the primary mount or additional units attached to the same line.
The zipSTOP Brake Unit is attached to the Primary Anchor Point using three M12 or ½” fixing bolts.
Loads at Primary Anchor Point
In-line with Braking Line6.0 kN
Right angles to Braking LineNegligible
The loads specified are applied loads for the zipSTOP Brake Unit only. These loads DO NOT allow for additional loads applied by other equipment or structures. Ensure sucient
factor of safety is applied in the structural design of all zip line installations.
9.4 Secondary Anchor Point
The Secondary Anchor Point provides support for redirection pulleys and hardware used in the Redirection
Line setup. The design of the Secondary Anchor Point must be sucient to withstand all applied loads experienced during zip line operation.
Loads specified are for zipSTOP Brake assembly installation only and do not allow for any additional equipment or other loadings applied to the secondary mount including redirection lines for additional units.
Loads at Secondary Anchor Point
Inline with Redirection Line11.0 kN
Right angles to Redirection Line3.5 kN
The loads specified are applied loads for the Redirection Line and Redirection Pulley only.
These loads DO NOT allow for additional loads applied by other equipment or structures.
Ensure sucient factor of safety is applied in the structural design of all zip line installations.

Page 35
9.4.1 POSITION OF THE SECONDARY ANCHOR POINT
The Secondary Anchor Point is located in line with the start of the Arrest Zone (Brake Trolley Reset Point). It
provides the location for the attachment of the Type I Pulley above the zip line and also attachment of any
secondary or support lines that may be required.
Ensure the Secondary Anchor Point and any supporting structure are at least one meter above the zip line and at
a sucient distance from the zip line to prevent contact with the rider, redirection line, and other equipment.
Always install pulleys so as to prevent any tangling, snagging or binding with other lines or objects. Ensure that
the Redirection Line is routed cleanly and in line through the pulley system to prevent contact with any surface
other than the pulley sheaves.
9.5 Redirection and Support Lines
All lines must be sewn, spliced, or properly terminated.
Only use an approved termination method for all rope connections. Using a Double Figure 8 knot to terminate a Redirection Line is not recommended by Head Rush Technologies for lines with Spectra or Dyneema
sheaths. Spectra and Dyneema have low coecients of friction which can result in knots becoming untied. A
Double Figure 8 knot also reduces line strength by 20-25% when tied properly and can reduce line strength by
more if tied incorrectly.
All Redirection Lines and support lines are to be manufactured to specified strength and are to be suitable for
all-season outdoor. When installing redirection and support lines, use route lines to ensure that:
All lines are installed in such a way as to prevent loose or sagging lines, tangling, snagging or binding with
other zip line components.
Lines are to be routed to eliminate abrasion and undue wear.
All lines are laid out so as not to present a tripping or injury hazard to zip line sta or riders.

9.6 Fitting zipSTOP Brake Unit
The zipSTOP Brake Unit may be mounted horizontally or vertically. The mounting bracket is designed for use
with a flat or curved surface. Curved surfaces must have a minimum 150 mm (6“) diameter.
ONLY INSTALL THE ZIPSTOP BRAKE UNIT ORIENTED DIRECTLY INLINE WITH THE TYPE 1 PULLEY
The Braking Line feeds straight out of the device, without twist, and centered within the Nozzle. Accelerated Braking Line wear may occur if the line bears onto the Nozzle edge.
DO NOT REUSE SELFLOCKING NUTS
Always use new nuts, as reuse of self-locking nuts may compromise connection integrity. This type of nut
is used on the Brake Trolleys.
Fit the zipSTOP Brake Unit as follows:
INSTALLATION NOTES
Always orient the zipSTOP Brake Unit directly in line with Type I Pulley.
Always use through bolts with large washers and self locking nuts.
It is recommended that double helix spring washers are located under mounting nuts to allow for movement in
primary mount point when used on a wooden structure or use split ring washer or comparable with a rigid structure
to reduce risk of loosening due to vibration
Always mount the zipSTOP Brake Unit a sucient distance from the zip line so that Redirection Lines and pulleys do
not interfere with rider.
Once installation is complete ensure the zipSTOP Braking Line is not twisted and feeds linearly through the Nozzle.

9.7 Fitting the Brake Trolley
The Brake Trolley is installed on the zip line and is used to transfer the energy of the rider to the zipSTOP Braking
Unit.
ALWAYS USE THE CORRECT BRAKE TROLLEY SIZE FOR THE ZIP LINE
Failure to use the correct size may prematurely wear the trolley or zip line.
ENSURE THAT THE ZIPSTOP BRAKING LINE IS FULLY RETRACTED INTO THE ZIPSTOP DEVICE
AT BRAKE INITIATION
If any Braking Line is extended, braking force will be increased, resulting in participant injury or damage to
the zipSTOP Brake Unit. Ensure brake trolley and zipSTOP are properly reset before every run.
NOT RECOMMENDED FOR LOW TENSION LINES WITH OFFSET REDIRECTION PULLEY
Oset redirection pulleys should only be used with highly tensioned zip lines. Slack zip lines may cause
binding and excessive wear on the brake trolley.
To fit the Brake Trolley:
INSTALLATION NOTES

9.8 Fitting Type I Pulley
ZSIR15020A THIS PRODUCT CAN ONLY BE USED WITH 1:1 REDIRECTION SETUPS
The zipSTOP IR (ZSIR150-20A) is NOT compatible with external redirection setups in any way. Installing
a redirection setup with the zipSTOP IR can create a very dangerous set of braking conditions that could
result in abnormally abrupt late braking.
The Type I Pulley is fitted to the Secondary Anchor Point, and provides both support and a means of redirection for the Redirection Line. The Type I Pulley is required for both 1:1 and 2:1 Redirection Ratio setups. The
Type I Pulley may be fixed horizontally or vertically to a solid surface or be clamped to a cable. The Type I
Pulley incorporates dedicated line attachment points for dead-end loops.
Fit the Type I Pulley as follows:
INSTALLATION NOTES
Always position the Type I Pulley higher than the zip line. A minimum of 1.0 meter (39.37”) is required. Ensure the position of the pulley will not allow contact or interference between the rider and any lines or equipment. Ensure the redirection pulley meets the load requirements as defined in this manual Ensure the Type I pulley assembly is mounted on a load bearing surface capable of withstanding all applicable load
bearing requirements.
Ensure that the Redirection Line is routed cleanly and in line through the pulley system, to prevent contact with any
surface other than the pulley sheaves. Fixed support pulley(s) can be used to ensure that Redirection Lines are kept
free and clear.

10. OPERATION OF zipSTOP
10.1 Safety Precautions
ALWAYS CORRECTLY INSTALL, MAINTAIN AND OPERATE THE ZIPSTOP BRAKE ASSEMBLY
Failure to do so may result in serious injury or death to participants.
ALWAYS OPERATE A ZIPSTOP BRAKE ASSEMBLY WITH AN EMERGENCY ARREST DEVICE EAD
ACTIVE
Failure to do so may result in serious injury or death to participants
ALWAYS CARRY OUT UNMANNED TESTING TO DETERMINE ACTUAL BRAKING DISTANCE
The information contained in this manual is intended for guidance only. Calculated braking distances for
the zipSTOP Brake Assembly are estimates only and may dier from actual braking distances achieved on
individual zip lines.
ALWAYS OPERATE WITH RIDER FACING FORWARD UPON ARRIVAL INTO THE ARREST ZONE
Serious injury due to upswing may result if rider is not in the forward-facing position. Arrivals without
orientation control should be verified such that minimum and maximum rider weight patrons cannot come
into contact with the line, brake trolley, or other equipment during deceleration when arriving backwards
uncontrolled.
ALWAYS USE THE CORRECT ZIPSTOP BRAKE TROLLEY
Failure to use the correct trolley may compromise system operation and result in serious injury to rider.
AVOID CONTACT BETWEEN RIDER AND RIDER TROLLEY AND/OR BRAKE TROLLEY
Serious injury may result if rider is in contact with trolley when it impacts the Brake Trolley. Always design
the zipSTOP installation so rider cannot be in contact with, or have any part of their body caught between,
the rider trolley and Brake Trolley.
ENSURE ALL CABLES, ATTACHMENT LINES AND PULLEYS ARE CORRECTLY ATTACHED AND
MAINTAINED
Ensure that the Redirection Line is routed cleanly and in line through the pulley setup, to prevent contact
with any surface other than the pulley sheaves. Any tangling, snagging, binding and abrasion may compromise system operation and result in serious injury to rider.
AVOID MAXIMUM LINE EXTENSION OF BRAKING LINE
Repeated extension of braking line to maximum Line Extension (LEX as defined in this manual) will cause
premature wear and void warranty coverage of the retraction spring.

Page 49
ENSURE BRAKE TROLLEY ALWAYS RESETS TO THE START OF THE ARREST ZONE
Failure to reset the Brake Trolley will compromise braking performance and may result in serious injury or
death and/or equipment damage.
THE BRAKE TROLLEY CANNOT BE TIED BACK IN ANY WAY, BY ANY METHOD, OR BY ANY
ACTION DURING OPERATIONAL HOURS
Any restriction of the brake trolley during operational hours may result in serious injury or death, or equipment damage.
10.2 zipSTOP Operation as a Primary Brake
The zipSTOP is designed to provide consistent and reliable braking to a zip line ride. Brake performance relies
on operators using the correct equipment and operating the zip line in accordance with the instructions contained within this manual.
THE ZIPSTOP BRAKE MUST:
Function without permanent deformation or failure of associated equipment. Arrest the motion of the rider regardless of rider orientation. Not inhibit rider retrieval in the event that arrest occurs before the landing area is reached.
10.3 zipSTOP Operation as an EAD
When used as an EAD the zipSTOP brake must be installed to engage upon failure of the primary brake, with
no action from the rider, in order to prevent serious injury or death to participants. The EAD will be installed as
either completely separate from the primary brake or as an integrated backup feature.
AN EAD MUST BE USED WHEN:
The rider arrives at the landing area at a speed over 6 mph (10 km/h). The rider encounters unintended harmful contact with terrain, objects, or people in the landing area.
10.4 Landing Areas
Landing areas are integral to the proper function of zip line braking, and shall:
Provide sucient space for brake operation and dismount procedures.
Provide protection from or limit unintended contact with zip lines, people, and other components.
Be free from hazards that require rider action to avoid. Objects in the landing area that have potential to
harm riders shall be covered with shock absorbing material.

Page 50
10.5 Operation During Extreme Weather Conditions
zipSTOP equipment has been designed for use in a wide range of temperature and weather conditions. Extreme heat and cold weather will not alter the performance of the equipment, nor will operations in wet conditions, however, the following should be observed:
WET LINE WARNING
When the line is wet it may slightly alter the performance of the zipSTOP device. This may result in increased braking distances and/or increased braking forces. Care must be taken when operating in wet
conditions.
When operating in freezing temperatures, it is of critical importance that all lines are kept dry. If lines become wet and subsequently freeze, normal retraction/extension may become limited, which may result in
increased or dangerous rates of deceleration or an increased likelihood of reset failure. If lines become wet
during freezing temperatures, or when normal extension/retraction becomes limited, cease all operation
immediately.
FULLY EXTEND BRAKING LINE TO ALLOW DRYING
When operating the zipSTOP in wet conditions, the Braking Line must be fully extended and allowed to
completely dry in order to get the longest life from the lines.
INSPECT LINE FREQUENTLY IN EXTREME WEATHER CONDITIONS
When operating in extreme wind, weather, temperature, humid conditions, UV light exposure, or near salt/
marine environments, increase line inspection frequency and replacement frequency. The line must be
replaced if any signs of deterioration are evident.
10.6 Resetting the Brake
CHECK BRAKE TROLLEY HAS CORRECTLY RESET AFTER EVERY RUN
The Unit is designed to stop retracting if there are any internal issues and in the case of many overload
situations. Any indication of a failure to reset should be checked and if found to be may be cause for immediate removal from service. Please contact your local service center for repair should the unit fail to reset
consistently.
BRAKE RESET FAILURE
Failure to reset the Brake Trolley will result in insucient braking and may result in serious injury or death of
rider.
The zipSTOP Brake Trolley should automatically return to the start of the Arrest Zone (Reset Position) once the
rider trolley is removed. With the Brake Trolley positioned in the Reset Position, the zipSTOP Braking Line will
be fully retracted.
www.headrushtech.com | +1-720-565-6885
51
Page 51
zipSTOP Brake Unit fully retracted
An arrival platform attendant should always check for the correct reset position of the Brake Trolley and the
zipSTOP Braking Line at the completion of each run, prior to a subsequent run. Redirection lines should be
visually checked after brake trolley reset to ensure they are running free and clear, have not become tangled,
etc.
If the Brake Trolley fails to reset, check that the zipSTOP Brake Unit is operating correctly and the Redirection
Line is not tangled, snagging, or binding.
10.7 Operational Retraction Spring Cycle Limit
Operational cycle limits for the zipSTOP are based upon fatigue limits of the internal retraction spring. Exceeding the life of the retraction spring will prevent the zipSTOP from automatically resetting but will not aect
the braking performance of the device. However, if the brake trolley does not reset, the rider will not be able
to engage the zipSTOP, resulting in no braking for the rider. There is no cycle limit for the core braking components of the zipSTOP. Do not continue to operate the zipSTOP if the brake trolley fails to consistently reset.
Operators must ensure the brake trolley resets before every zip run.
In order to maximize the life of the retraction spring, avoid extending the braking webbing (LEX) longer than
necessary. Repeated extensions of the webbing near the maximum line extension (12m / 39ft Model ZS125-08,
20m / 65ft Model ZSIR150-20A) will prematurely wear out the retraction spring and may void the warranty.
Extremely high throughput facilities may be required to send their devices in for recertification more frequently
than the annual requirement. Recertification includes replacement of this component and is a required and
necessary service for the zipSTOP.
Since webbing extension varies greatly for each installation and rider weight and speed, it is dicult to determine a cycle limit for the retraction spring. However the retraction spring in Model ZS125-08 should be capable of 10,000 cycles for a webbing extension of approximately 35 ft (11 m). The retraction spring for Model
ZSIR150-20A should be capable of 50,000 cycles at approximately 55 ft (17 m). Retraction Spring cycle limits
are approximations only and may decrease for extensions greater than that listed above. Facilities expecting
drastically higher throughput than this should expect an increased recertification period and may contact
Head Rush Technologies for more information.

11. TROUBLESHOOTING
Use this information to assist in troubleshooting problems that might occur during operation. If a problem cannot be resolved, remove components from service and contact your Head Rush Technologies Service Center.
SYMPTOMPOTENTIAL CAUSERESOLUTION
In most cases your redirection point has been established. Hopefully
this distance correlates to the performance of the brake you wanted to
achieve. If the braking performance is adequate and consistent consider
moving your redirection point further away and adapting to the longer
braking distance.
If you’re still within the safety window of your EAD and other equipment
consider using the higher speed and adjusting your redirection point to
allow for the longer braking distance. If speeds have become unsafe for
your equipment or your EAD consider adjusting your line tension to slow
arrival speed.
This is actually an optimal condition but may not be covered by the basic
table. More positive slope means more consistent arrival for your riders
regardless of weight and increased throughput on your lines. If rider speed
is within safety limits consider leaving this slope and adjusting braking
distance to allow for it. If your installation cannot accommodate the increased braking distance consider lowering the tension on your lines.
NOTE: REDUCING LINE TENSION MAY NEGATIVELY AFFECT THROUGHPUT AND MAY INCREASE THE NEED FOR RIDER RETRIEVAL. USE THIS
CORRECTION ONLY AS A LAST RESORT.

When appropriate, some installations may choose to use the zipSTOP

result in shortened braking distances and higher braking loads. In either
case, an increased pivot height or change to a ZSIR or 2:1 redirection ratio
will serve to increase braking distance and reduce loads.
If you’re installation is still well within the safety limits of your equipment
and EAD consider adding tension to your line or additional slope. Be aware
that additional tension will place additional load on your rider cable and
could take it out of operational safety limits. Alternatively, check friction in
your rider trolley.
NOTE: ONLY INCREASE LINE TENSION FOLLOWING DIALOGUE WITH A
PROFESSIONAL ENGINEER OR ZIP LINE INSTALLER.
Interference between safety carabiners or the bottom or sides of the
trolley on impact can have a radically increased eect on braking with
the additional drag. Not only will this interference radically degrade the
performance/lifespan of your components it makes braking distance very
hard to control. The camming will not be consistent rider to rider based
on weight and speed of arrival. Recommend changing trolleys or introducing a camming restrictor.

to customize the mounting location of the zipSTOP, traveler, support and/
or redirection pulleys to ensure straight webbing extraction during braking.
Alternatively, make sure crosswinds are not inducing large lateral angles in
your redirection line.
While gravity braking is a tried and true method of controlling arrival speed
it definitely will shorten the distance of braking after impact. In installations
with a lot of “belly” in the line this braking distance may be acceptable or
outside design parameters. Whenever possible consider removing slack
in the line and adjusting the zipSTOP and rigging for higher arrival speeds
(remember the zipSTOP can handle extreme speeds with redirections up
to 3:1). If arrival speed and recovery methodology is acceptable the redirection point can be moved in to facilitate the shorter braking/speed.
Braking

(continued)
Strong headwinds
High friction in a
cable interface
Incorrect angles
If the headwind is anomalous consider adjusting recovery methodology.
If headwinds are consistent and year round consider increasing the speed
of the line through tension if safety limits allow. Alternatively, adjust the
redirection point closer to the zipSTOP to allow for the shorter braking
distance IF and ONLY IF head winds are consistent. WARNING: Artificially
shortening the braking distance can result in EAD impact on days with
little or no head wind.
This is related specifically to friction in the trolley or brake trolley mechanism. Slack lines can allow the brake trolley and or rider trolley to impact
the zip line in non-standard locations or side surfaces. On jacketed cable
this can cause severe drag and wear impact on the zip line. In non-jacketed zip lines this still can add significant friction and wear. Attempt to keep
the loading of the slack cable and break line in the vertical plane during
impact whenever possible to eliminate side loading of devices. In installations where side loading is inevitable consider a 4 sheave brake trolley or
alternative rider trolley.
Ropes induce friction over tight and multiple angles. The more these ropes
are subjected to extreme angles the more friction will be experienced in
the redirection setup. Occasionally, these angles and additional loads are by
design in which case the redirection point can be shortened and the setup
compensated for the shorter distance braking. Other times this indicates a
redirection point that needs adjustment for angle and tension.

and add to the brake resistance of the zipSTOP. If counter weights are
being employed consider lowering the mass and if clothes line type reel
to reel assemblies are used ensure the friction is as low as possible and
the inertial weight of the components is as low as possible. ALWAYS: Make
sure these components are well clear of the zipSTOP and its redirection
lines and incapable of interfering by binding or cutting the redirection
lines.
If your speed is outside the limits for the device or redirection, braking will
be much more abrupt for your riders. Consider increasing external redirection ratio or using the zipSTOP Internal Redirection (IR) unit for speeds
up to 60km/h (37mph)
NOTE: IF YOU USE Redirection RATIONS OF GREATER THAN 2:1, YOU
WILL BE REQUIRED TO RE-SET THE BRAKING DEVICE AFTER EVERY DESCENT.
Interference between safety carabiners or the bottom or sides of the
trolley on impact can have a radically increased eect on braking with
the additional drag. Not only will this interference radically degrade the
performance/lifespan of your components it makes braking distance very
hard to control. The camming will not be consistent rider to rider based
on weight and speed of arrival. Recommend changing trolleys or introducing a camming restrictor.
Webbing extended at
impact
www.headrushtech.com | +1-720-565-6885
Any webbing extended from the zipSTOP at the time of impact will increase
the speed at which the brake applies full force. In many instances this can and
will lead to abrupt and undesirable braking. Unless by design, and thoroughly
tested at max and minimum rider weights at max speed, the webbing should
never be extended prior to brake engagement. SLACK LINE: In slack line
installations it should be noted that the distance between the rider line and
redirection point dynamically grows as the rider approaches the impact point
due to cable deflection and this results in increased brake force application. In
most instances this will be within operational limits as the webbing will have
most of its pre-extraction on only the heaviest riders. Adjust your redirection
point and length of redirection line as necessary to ensure full reset of the
zipSTOP webbing.

at the zipSTOP webbing to redirection line interface to ensure smooth operation. In installations where an overhead line has not been implemented
consider adding at least a short line to accommodate a traveler mechanism.
The retraction force on the line is at its lowest point as the webbing nears
full retraction. Eliminating any resistance at the webbing nozzle by controlling the angle of the webbing will help ensure full reset every time. The

Use properly spaced support pulleys to support the weight of the redirection line. Support pulleys may be mounted to the overhead line to support
the weight of the redirection line and/or to prevent the line from becoming
entangled. You must ensure the location of the support pulleys will not
interfere with the extension of the webbing/traveler assembly. This is especially important if using heavy redirection line or when operating in high
wind. Fixed support pulleys are typically not used with ZS IR.

12.8 Webbing Line Inspection
BRAKING LINE MUST BE REPLACED IMMEDIATELY IF IT IS WORN OR DAMAGED OR AT 12
MONTH INTERVALS, WHICHEVER COMES SOONER
Failure to do so may result in equipment failure, serious injury or death to participants.
The Braking Line is the line that extends during the zipSTOP activation. The inside end of the Braking Line
attaches to the zipSTOP Brake Unit via a Shackle Link to assist with ease of replacement.
To inspect the Braking Line, Drum Lead, and Shackle Link:
1. With zipSTOP Brake Unit securely mounted and nozzle removed, pull out the full extent of Braking Line.
Refer to Webbing Replacement section for nozzle removal procedure.
2. Place a suitable pin through the loop in the Drum Lead, above the joining link, to prevent it from retracting back into the unit.
3. Inspect the Braking Line and Drum Lead by passing it slowly through your hands under a good light.
Inspect the Braking Line for:
Damage to stitching (cuts or abrasion).
Cuts to Braking Line, especially to edges.
Abrasion across the surface of the Braking Line, wear and fraying, especially to the edges and the
Braking Line loops.
UV degradation – although dicult to detect, visual indications are discoloration, fading, brittleness,
and chalking of the Braking Line surface.
Chemical attack, this can result in soft or weak fibers, color change or flaking of the surface.
Heat or friction damage, indicated by hard fibers or glazing of the surface.
Contamination from dirt, grit, sand, or rust.
Twisting, knotting or permanent deformation of Braking Line
Replace the Braking Line if any signs of damage or deterioration are present.
4. Inspect the Shackle Link, ensuring that:
The shackle pin is secure and straight. Do not attempt to tighten as this may break the thread locking
compound and allow the pin to loosen over time.
The shackle is undamaged and in the correct orientation.
The webbing around link is not worn or damaged.
5. Remove the retaining pin and slowly retract the Braking Line into the casing, checking the action is
smooth and adequate spring resistance is felt. Ensure to not allow the webbing line to twist during
retraction.
6. Refit the Nozzle Assembly.
7. Once line is fully retracted, pull out line a short distance using reasonable force and allow it to retract.
Repeat two to three times to ensure line is firmly wound onto the drum.
8. Return zipSTOP Brake Unit to service and check for correct operation.

13. BRAKING DISTANCE CHARTS
CAUTION
Always complete unmanned testing to determine actual braking distances and allowable swing up of rider
at given weight and arrival speed. Riders stopping too abruptly will swing up and potentially contact the
cable. Do not operate the zipSTOP with an excessive amount of rider swing up.
Calculated braking distances shown on charts are for guidance use only. Actual braking distances will vary
due to site conditions, weather conditions and final configuration of zip line set-up.
Braking distances shown on charts refer to installations where zipSTOP Braking Line is fully retracted when
Brake Trolley is positioned at the start of the Arrest Zone (Reset Position). If zipSTOP Braking Line is not fully
retracted when Brake Trolley is reset, then actual braking distance will be dierent to that shown on the chart.
Braking distances that fall below the ‘BDmin’ line will result in high level of braking force being felt by the
rider, and may cause severe swinging up of the rider’s body during braking.
Distances listed are only a starting point and may need to be adjusted based on individual installations.
THE BRAKING LINE MUST BE FULLY RETRACTED INTO THE ZIPSTOP AT THE POINT OF BRAKE
INITIATION
Serious injury, death, or damage to equipment can occur if Brake initiation occurs without a fully retracted
Braking Line.
SAFE OPERATION IS CONTINGENT UPON OPERATING WITHIN THE PERFORMANCE CHARTS
BELOW
Operating outside of these parameters may result in equipment damage or in injury or death of the rider.

ENSURE RETRIEVAL ROPE DOES NOT BECOME ENTANGLED
Always ensure the retrieval rope used in conjunction with this device does not become entangled with trolley
path, any fixed object, including the zip line, or the rider. Entanglement with a fixed object may prevent the
brake trolley traveling over the entire braking distance. Entanglement with the rider may cause rope burn,
other injuries or asphyxiation if wrapped around the neck. If you have any concerns or issues with the retrieval
rope contacting the rider in a manner that is unsafe, consider using a rope that is conveyed or tossed to the
rider after arrival and capture. The implications and liability of having a retrieval line near the passenger during
deceleration are at the discretion and testing of the operator.
Always perform unmanned testing prior to rider commissioning to ensure system is operating correctly.

15.3 zipSTOP Pivot Mount
The zipSTOP Pivot Mount is an upgrade accessory used to expand the mounting possibilities of the zipSTOP
and zipSTOP IR Zip Line Braking Devices. Proper use of the zipSTOP Pivot Mount will allow for smooth braking, reduced wear on the webbing, improved retraction, and simplified installation. The zipSTOP Pivot Mount
is designed to be used directly overhead and in line with the zip line. The installation point should be directly
above the point where braking is to begin. Please reference the zipSTOP/zipSTOP IR applicable sections above
for full specifications, including braking distances and appropriate mounting height.
82
www.headrushtech.com | +1-720-565-6885
Page 82
THE ZIPSTOP PIVOT MOUNT IS NOT DESIGNED OR INTENDED FOR USE WITH ANY OTHER DEVICE
The zipSTOP Pivot Mount has been specifically engineered for safe use with only the zipSTOP line of devices.
Both zipSTOP and zipSTOP IR Zip Line Braking devices can utilize the Pivot Mount, but the Pivot Mount must
be used without any external redirection (i.e. in a 1:1 redirection line configuration only). Please reference the
zipSTOP applicable sections of this manual for arrival speeds, rider weight, and full specifications when determining mounting location. Installation of the zipSTOP Pivot Mount with the wrong device may result in improper operation and potentially hazardous or dangerous braking conditions. Operation MUST meet the operational
and safety guidelines set forth in the Operator’s Manual. Operators should double check and verify the safety
limits set forth in the Operator Manual and conduct weight testing before live operation.
The zipSTOP Pivot Mount is a mounting accessory for the zipSTOP and zipSTOP IR devices only.
The zipSTOP Pivot Mount is NOT COMPATIBLE with the QUICKjump Free Fall device, TRUBLUE
Auto Belay, or any device other than the zipSTOP Zip Line Brake Devices.
15.3.1 COMPOSITION
The zipSTOP Pivot Mount consists of two aluminium plates – one on either side of the zipSTOP central plate.
The aluminium plates are secured by two through bolts which attach the zipSTOP/zipSTOP IR as shown in
the figure below. The third bolt serves as the pivot point and connection location for the quick link which is
mounted at the top and between the aluminium plates.
15.3.2 MOUNTING
The zipSTOP Pivot Mount is designed to be attached via the designated mounting point and quick link only. A
secondary, longer, non-loaded tether should be connected between the anchor point and the exposed handle
as a backup connection. Ensure the mounting hardware is secure and the unit is free to pivot, unrestricted, in
the appropriate direction.
USE ONLY THE DESIGNATED MOUNTING POINT
Use only the correct, designated mounting point. Use of incorrect points can result in equipment damage.
Ensure all mounting hardware is secure but free to pivot in the mounting point. All anchor points and connectors used must conform to any applicable federal, state, or local requirements for such devices. The primary anchor point strength, connectors, redirection line, and other hardware and accessories must conform
to all requirements set forth in the zipSTOP/zipSTOP IR Operator Manual.

15.3.4 PERFORMANCE
Use zipSTOP Braking Distance charts in the zipSTOP Operator’s Manual and the diagram below to determine
braking distances and performance. Due to the direct connection between the unit and the brake trolley in the
zipSTOP Pivot Mount setup, the braking distances may be shorter than in the zipSTOP Braking Distance charts.
Use the zipSTOP Braking Distance charts only as a starting point for tuning performance and braking distance
as external and installation factors can change performance.
