2.0 SYSTEM REQUIREMENTS

2.1 ANCHORAGE: Anchorage structure requirements vary with the system application and whether it is a certied

anchorage9 or non-certied anchorage10. The structure to which a Fall Arrest, Restraint, Work Positioning, or Rescue
system is attached must sustain static loads applied in the directions permitted as shown in the following table. Anchorage

strength requirements, along with system applications, are specied below, unless noted or dened otherwise in Table 1:

Fall Protection System Certied Anchorage

9

Non-Certied Anchorage

10

Dened by

Fall Arrest 2 times maximum arresting force 5,000 lbf (22.2 kN) OSHA, ANSI

Restraint/Travel Restraint 2 times foreseeable force

1,000 lbf (4.4 kN) per ANSI

5,000 lbf (22.2 kN) per OSHA

OSHA, ANSI

Work Positioning 2 times foreseeable force 3,000 lbf (13.3 kN) OSHA, ANSI
Rescue 5 times applied load 3,000 lbf (13.3 kN) ANSI

When more than one system is attached to an anchorage, the strengths stated above must be multiplied by the number

of systems attached to the anchorage. See ANSI Z359.2 for more information.

2.2 PERSONAL FALL ARREST SYSTEM: Figure 1 illustrates the application of this Anchorage Connector. Personal Fall
Arrest Systems (PFAS) used with the system must meet applicable Fall Protection standards, codes, and requirements.
The PFAS must incorporate a Full Body Harness and limit Arresting Force to the following values:

Maximum Arresting Force Free Fall
PFAS with Shock Absorbing Lanyard 1800 lbf (8 kN)
PFAS with Self Retracting Device (SRD) 1800 lbf (8 kN)

Refer to the instruction(s) included with your
Lanyard or SRD for Free Fall limitations.

2.3 FALL PATH AND SRD LOCKING SPEED: A clear path is required to assure positive locking of an SRD. Situations
which do not allow for an unobstructed fall path should be avoided. Working in confined or cramped spaces may not allow
the body to reach sufficient speed to cause the SRD to lock if a fall occurs. Working on slowly shifting material, such as
sand or grain, may not allow enough speed buildup to cause the SRD to lock.

1 Fall Arrest System: A collection of Fall Protection Equipment congured to arrest a free fall. Protects the user in the event of a fall. Free fall is permitted up to

the limits allowed by the connecting device (either an Energy Absorbing Lanyard or Self-Retracting Device (SRD)).

2 Restraint System: A collection of Fall Protection Equipment congured to prevent the person’s center of gravity from reaching a fall hazard.Prevents the user

from reaching a hazard. No verical free fall is permitted.

3 Work Positioning System: A collection of Fall Protection Equipment congured to support a user at a work position. Must include a back-up personal fall

arrest system. Maximum permissible free fall is 2 feet.

4 Rescue System: A collection of Fall Protection Equipment congured to remove a person from danger, harm, or connement to a safe location. No vertical free

fall is permitted.

5 Competent Person: One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary,

hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.

6 User: A person who performs activities while protected by a Fall Protection system.
7 Authorized Person: A person assigned by the employer to perform duties at a location where the person will be exposed to a fall hazard.
8 Rescuer: Person or persons other than the rescue subject acting to perform an assisted rescue by operation of a rescue system.

9  Certied Anchorage: An anchorage for fall arrest, positioning, restraint, or rescue systems that a Qualied Person certies to be capable of meeting the

criteria for a certied anchorage according to Section 2.1.

10  Non-Certied Anchorage: A fall arrest anchorage that a Competent Person can judge to be capable of supporting the predetermined anchorage forces

listed in Section 2.1.

2.4 HAZARDS: Use of this equipment in areas with environmental hazards may require additional precautions to prevent
injury to the user or damage to the equipment. Hazards may include, but are not limited to: heat, chemicals, corrosive
environments, high voltage power lines, explosive or toxic gases, moving machinery, sharp edges, or overhead materials
that may fall and contact the user or Personal Fall Arrest System.

2.5 FALL CLEARANCE: Figure 3 illustrates the components of a Fall Arrest. There must be sucient Fall Clearance (FC)
to arrest a fall before the user strikes the ground or other obstruction. Clearance is aected by a number of factors

including: Anchorage Location, (A) Lanyard Length, (B) Lanyard Deceleration Distance or SRD Maximum Arrest Distance,
(C) Harness Stretch and D-Ring/Connector Length and Settling. Refer to the instructions included with your Fall Arrest

subsystem for specics regarding Fall Clearance calculation.

2.6 SWING FALLS: Swing Falls occur when the anchorage point is not directly above the point where a fall occurs (see Figure

4). The force of striking an object in a swing fall may cause serious injury or death. Minimize swing falls by working as directly

below the anchorage point as possible. Do not permit a swing fall if injury could occur. Swing falls will signicantly increase the

clearance required when a Self-Retracting Device or other variable length connecting subsystem is used.

2.7 COMPONENT COMPATIBILITY: 3M equipment is designed for use with 3M approved components and subsystems
only. Substitutions or replacements made with non-approved components or subsystems may jeopardize compatibility of

equipment and may aect the safety and reliability of the complete system.

2.8 CONNECTOR COMPATIBILITY: Connectors are considered to be compatible with connecting elements when they
have been designed to work together in such a way that their sizes and shapes do not cause their gate mechanisms to
inadvertently open regardless of how they become oriented. Contact 3M if you have any questions about compatibility.

Connectors (hooks, carabiners, and D-rings) must be capable of supporting at least 5,000 lbf (22.2 kN). Connectors

must be compatible with the anchorage or other system components. Do not use equipment that is not compatible.
Non-compatible connectors may unintentionally disengage (see Figure 5). Connectors must be compatible in size, shape,
and strength. If the connecting element to which a snap hook or carabiner attaches is undersized or irregular in shape, a
situation could occur where the connecting element applies a force to the gate of the snap hook or carabiner (A). This force
may cause the gate to open (B), allowing the snap hook or carabiner to disengage from the connecting point (C).

Self-locking snap hooks and carabiners are required by ANSI Z359 and OSHA.

2.9 MAKING CONNECTIONS: Snap hooks and carabiners used with this equipment must be self-locking. Ensure all
connections are compatible in size, shape and strength. Do not use equipment that is not compatible. Ensure all
connectors are fully closed and locked.

3M connectors (snap hooks and carabiners) are designed to be used only as specied in each product’s user’s instructions.

See Figure 6 for examples of inappropriate connections. Do not connect snap hooks and carabiners:
A. To a D-ring to which another connector is attached.
B. In a manner that would result in a load on the gate. Large throat snap hooks should not be connected to standard

size D-rings or similar objects which will result in a load on the gate if the hook or D-ring twists or rotates, unless the
snap hook complies is equipped with a 3,600 lbf (16 kN) gate. Check the marking on your snap hook to verify that it
is appropriate for your application.

C. In a false engagement, where features that protrude from the snap hook or carabiner catch on the anchor, and

without visual conrmation seems to be fully engaged to the anchor point.

D. To each other.
E. Directly to webbing or rope lanyard or tie-back (unless the manufacturer’s instructions for both the lanyard and

connector specically allows such a connection).

F. To any object which is shaped or dimensioned such that the snap hook or carabiner will not close and lock, or that

roll-out could occur.

G. In a manner that does not allow the connector to align properly while under load.

3.0 INSTALLATION

The owner of this equipment may contact 3M Technical Services with any questions regarding equipment installation, use,

;

or inspection.

Installation of the DBI-SALA Trolley Anchor must be performed or supervised by a Competent Person1.

;

1

2

3.1 PLANNING: Plan your Fall Protection system prior to installation of the Trolley Anchor. Account for all factors that may

affect your safety before, during, and after a fall. Consider all requirements, limitations, and specications dened in

Section 2 and Table 1.

3M shall make available upon request information that is necessary for the design and planning of systems.

;

3.2 SELECTING AN ANCHORAGE BEAM: The Trolley Anchor may be installed on horizontal and level beams meeting the

anchorage requirements specied in Table 1. The beam must have End Stops (A) at each end to prevent the trolley from

rolling off the beam. See Figure 10 for reference. The end stops must be sized and positioned such that they are able to
safely stop the trolley. The trolley should not catch or hang on the end stop; the trolley must be able to freely return in
the opposite direction after touching the end stop.

Joints between beam sections must be ush to allow the Trolley Anchor to pass over smoothly.

;

3.3 INSTALLING THE TROLLEY ANCHOR: The Trolley Anchor can be installed on beams meeting the anchorage

requirements specied in Table 1. See Figure 1 for the Beam Trolley measurements. Figure 7 illustrates installation of the

Trolley Anchor. To install the Trolley Anchor:

1. Measure the beam ange width to determine the Adjustment Hole settings on the Trolley. Figure 7.1 and Table 2

illustrate the hole positions on the left and right Adjuster Dials and the Load Bar that correspond with Table 2. Record
these Adjustment Hole settings and use them for Step 3 and 4.

2. To open one side of the trolley, remove the Pull Ring from the Clevis Pin and pull the Clevis Pin up out of the Adjuster
Dial. Slide the Side Plate off the Load Bar.

3. On the still assembled side of the Trolley, remove the Pull Ring and Clevis Pin from the Side Plate, and adjust the
width to the required Adjustment Hole settings determined in Step 1 and from Table 2. Lock the adjustment into
place by re-installing the Clevis Pin vertically with the Clevis Pin Head on top through the appropriate Adjustment Dial
and Load Bar holes and installing the Pull Ring.

4. Place the partially assembled Side Plate and Load Bar onto the bottom ange of the beam with the Connector Ring
hanging down. Slide the un-assembled Side Plate onto the Load Bar and align with the required Adjuster Dial and
Load Bar holes as determined in Step 1. Install a Clevis Pin vertically, with the Clevis Pin head on top, through the
Adjuster Dial and Load Bar holes and secure with the Pull Ring.

Trolley width settings specified in Table 2 must be followed. Adjustments on the Load Bar must use the same

;

setting on both sides (e.g. A - A, B - B, etc.). Adjustments on the Adjuster Dial must be within one unit. Failure to
use correct settings may improperly load the Trolley. If the beam ange is too wide to install the Clevis Pin through
the correct holes, adjust the Trolley to the next larger beam ange size as specified in Table 2. The D-Ring must

always be centered between the two Side Plates.

5. Conrm the distance from the Trolley Wheel face (C) to the edge of the beam ange (D) is no more than 1/16 in.
(1.6 mm). If the distance is greater than 1/16 in. (1.6 mm), change the Adjuster Dials to the next narrower setting in
Table 2. Also, visually conrm the Clevis Pins (A) are installed with the pin heads on top of the Adjuster Dials and that
the Pull Rings (B) are fully installed through the Clevis Pin holes.

If the trolley is moved to another beam, or if the Pull Rings are removed, the circle type pull rings are reusable.

;

If a cotter pin is used, a new cotter pin is to be used for each new installation. Use 5/64 x 3/4”, 18-8 stainless
steel Pull Rings or Pivot Point bow-tie™ clip Pull Rings. If you are using Pivot Point bow-tie™ clips, they are also

reusable. Only use the original clevis pins. Do not make substitutes.

4.0 USE

4.1 BEFORE EACH USE: Verify that your work area and Fall Arrest system meet all criteria dened in these instructions.
Verify that a formal Rescue Plan is in place. Inspect the product per the ‘User’ inspection points dened in the “Inspection
