3.0 Safety warnings

1. Read and understand the entire owner's
manual before attempting assembly or
operation.

2. Read and understand the warnings posted on
the machine and in this manual. Failure to
comply with all of these warnings may cause
serious injury.

3. Replace warning labels if they become
obscured or removed.

4. This chain hoist is designed and intended for
use by properly trained and experienced
personnel only. If you are not familiar with the
proper and safe operation of a chain hoist, do
not use until proper training and knowledge
have been obtained.

5. Do not use this chain hoist for other than its
intended use. If used for other purposes, JET
disclaims any real or implied warranty and
holds itself harmless from any injury that may
result from that use.

6. Do not install this chain hoist where explosive
hazards may exist.

7. Give your work undivided attention. Looking
around, carrying on a conversation and “horse­play” are careless acts that can result in
serious injury.

8. Do not use to lift people, or loads over people.
Warn others in the vicinity when lifting or
transporting a load. Avoid swinging load and
hook.

9. Do not exceed the rated lift capacity of the
chain hoist.

10. Make sure limit switches are operating
properly. Do not use limit switches as routine
operating stops; they are emergency devices
only.

11. Verify that load chain is properly seated in load
sheeve before operating hoist.

12. Do not use the load chain as a sling or wrap
load chain around the load.

13. Always inspect the chain hoist for damage
prior to use. Do not use a chain hoist with
twisted, kinked, worn or otherwise damaged
chain. If the chain hoist is damaged, do not
use until it has been repaired or replaced.

14. Do not use more than one chain hoist to lift or
move a load. If this is unavoidable, each chain

hoist must have the same capacity as the load
to be moved.

15. Never allow the load chain to “set” over sharp
edges. All lifts must be made with straight
chain that is free of obstacles.

16. Do not use chain hoist unless load is centered
between top and bottom hooks.

17. Protect load chain from weld splatter and other
contaminants. Do not allow the hook or chain
to be contacted by a live welding electrode.

18. Always take time to study the job to be
performed and choose the safest method. Do
not place yourself or other people in an unsafe
position. Maintain constant awareness of the
lifting environment.

19. Leave all internal maintenance to a qualified
JET service center. Do not alter settings on the
inverter. If its function is suspect, contact JET
technical service for assistance.

20. Disconnect hoist from power source before
performing maintenance or opening the
housing.

21. Do not leave a suspended load unattended.

22. Replace the chain with factory replacement
chain only. Do not use any other type of chain.

23. Never use the chain hoist if either hook is
stretched, deformed, or has a broken or
missing safety latch. Always replace the safety
latch and/or the hook before placing the chain
hoist back into service.

24. Keep safety guards in place at all times when
the hoist is in use.

25. Do not operate this hoist while tired or under
the influence of drugs, alcohol or any
medication.

26. This hoist is not designed for exposure to
outdoor elements.

27. Understand and follow all procedures as set
forth in American National Standards titled
Overhead Hoists (Underhung), ANSI/ASME
B30.16. This standard is available through the
American Society of Mechanical Engineers at
www.ASME.org.

3.1 Important notice

It is the responsibility of the owner/user to install, inspect, operate and maintain this hoist in accordance with
OSHA regulations and ANSI/ASME B30.16, “Overhead Hoists (Underhung)”, along with any state or local
codes/ordinances as applicable. If hoist is installed as part of a total lifting system (trolley, crane, monorail,
etc.), or if below-the-hook lifting devices will be used, it is the responsibility of the owner/user to comply with
any standards or regulations involving those additional elements of the system.

4.0 Product introduction

Your JET variable speed hoist is designed and constructed to provide consistent, long-term operation if used in
accordance with the instructions set forth in this manual.

JET VOLT hoists are available in 230 volt/dual phase; 230 volt/3-phase or 460 volt/3-phase configuration, as
well as varied chain lengths.

The Variable Frequency Drive, or “inverter,” offers variable speed within a pre-established range. This allows
lifting or descent of loads at reduced speeds without having to toggle the up/down button, thus providing
efficiency and reducing stress on control contactors.

The magnetic disc brake provides dependable and rapid stopping of chain movement without hook drift, and
produces less wear on brake elements than standard mechanical braking systems, thus reducing maintenance.
The hoist is also provided with thermal overload protection and limit switches.

This hoist complies with ANSI/ASME B30.16 and HST-1 standards.

5.0 About this manual

This manual is provided by JET covering the safe operation and maintenance procedures for the JET VOLT
series hoists. This manual contains instructions on installation, safety precautions, general operating
procedures, maintenance instructions and parts breakdown for your hoist. It is not intended to be an exhaustive
guide to the use of hoists or the broad subject of rigging, and cannot anticipate every system or lifting
configuration in which this product may be used.

Retain all instructions and safety warnings for continued reference. If the hoist transfers ownership, the manual
should accompany it.

If there are questions or comments, please contact either your local supplier or JET. JET can also be reached
at our web site: www.jettools.com.

Read and understand the entire contents of this manual before installing hoist or

attempting operation, adjustment or maintenance. Failure to comply may cause serious injury.

6.0 Glossary

Creep speed: Slow, constant, fixed rate of motion
of a hoist.

Duty cycle: The amount of work a hoist can
perform in a given period of time, generally
measured by maximum run time and number of
starts within that period. Duty cycle ratings are
designated H1 through H5.

Duty class: Identifies the type of service for which
a hoist is designed, designated A through F.

Headroom: Minimum distance between saddle of
top hook to saddle of load hook, measured when
load hook is at upper travel limit. Smaller
headroom allows a hoist to fit in tighter work
spaces.

Hook saddle: The inside arc of the hook which
contacts the beam (top hook) or where the load
sling is seated (load hook).

Toggle or “bump fire”: Rapid press and release
of a control button to raise or lower load in
intermittent steps. (A variable frequency drive in
lowest speed range often eliminates the need for
toggling.)

Overtravel limit device: A device for limiting
upward or downward travel of the load hook at the
extremities of its lift. (If activation of the device
alters the electrical circuit within the machine, it is
often called a “limit switch.”)

Load block: The assembly of hook or shackle,
swivel, bearing, pins, sheaves and frame
suspended by the chain.

Magnetic disc brake: A stopping device controlled
by the application of electrical current to the coil of
an electromagnet, which draws away an armature
allowing rotation of the shaft. When the magnet is
de-energized, the armature moves back toward the
brake face and squeezes together friction discs –
the torque is applied to the hub and stops shaft
rotation.

Overload limit device: A mechanical or electrical
device that prevents the hoist from lifting when
excessive load is applied.

Rated Load, or Capacity: The maximum load
weight, usually labeled as tonnage, which the hoist
is designed to handle as designated by the
manufacturer.

Reeving: The system in which a chain or rope
travels around a running sheave.

Running Sheave: A sheave which engages the
chain/rope and rotates as the load block is raised
or lowered. Also called “load sheave” or “load
sprocket.”

Variable frequency drive (“inverter”): A control
system that converts fixed line voltage and
frequency into a three-phase system with infinitely
variable voltage and frequency, in order to regulate
motor speed.

1 Product registration card
1 Test certificate

10.0 Installation

Support for the hoist may be hook, clevis pin,
trolley, or beam clamp. Whatever method of
suspension is chosen, the support components
must be rated equal to, or greater than the
capacity of the chain hoist. Supporting structures
(such as I-Beams) should be installed by properly
licensed professional installers.

If you are using the hoist with a trolley, refer to the
trolley manual for instructions on securing the
control cord and maintaining proper slack in the
cord during operation. Optional pendant cords for
use with a trolley system are shown in section

13.4.

Make sure the suspension system used is properly
grounded, in addition to the grounding of the hoist.

10.1 Installing power and control

cords

Attach the power supply cord and control cord to
the hoist as follows (see Figure 3):

1. Remove any protective caps from the plugs on
the power and control cords, and from the
sockets on the hoist.

2. Insert the 4-pin (4P) plug of the power supply
cord into the 4P socket on the hoist. Insert the
7P plug of the control cord into the 7P socket.
Orient the plugs properly; match the numbers
on the pins in each plug to those in the socket.
(The longest pin is the grounding pin, and
should insert into the socket hole with the
grounding symbol: ) Use sufficient force to
ensure good connection.

3. Tighten the two cover nuts. Hand-tighten only;
do not use a wrench.

4. The control cord has a cable loop to relieve
strain upon the power cord connection. On
1/4- to 2-ton models, secure this loop by
inserting it into the grooves of the clip, then
installing clip to bottom of hoist with the two

screws. See Figure 4. On 3- to 10-ton
models, secure the cable loop to the eyebolt
on the side of the hoist.

10.2 Lubrication

10.2.1 Gear oil

Your hoist has been shipped with oil included in
the gearbox. Before operating, verify the oil level
by removing the plug on the side of the hoist (see
Figure 5). The oil level should be just below the
edge of the hole.

Figure 5

9

The oil in the gearbox should be changed annually,
or more frequently under severe service, as
follows.

Use either of these recommended oil brands:

Mobilgear XMP 100
Shell Omala S2 G 100

Capacities:

1/4T,1/2T,1T Hoists – 0.8 Liters (0.21 gal)
2T,3T,5T,10T Hoists – 1.5 Liters (0.4 gal)

To drain and refill gearbox (refer to Figure 5):

1. Open vent plug on top of hoist.

2. Open drain plug and drain reservoir. Reinstall
drain plug.

3. Pour oil into fill hole.

4. Check level by removing side plug.

5. Reinstall top and side plugs.

10.2.2 Chain lubrication

Do not dump chain by hand

into the chain container! By not following the
above steps, the chain can become twisted or
kinked and can damage the hoist.

Figure 6

11.0 Electrical instructions

Periodically apply a light coat of 30W oil to the
chain. This will create easier operation and prolong
the chain’s life. For optimum results, clean chain
with an acid-free solution before oiling.

10.3 Chain container

Your hoist is supplied with a chain container
designed to fit the particular length of chain. If a
different length chain is ever installed on this hoist,
the chain container must be replaced by one of
proper size.

The chain container should be installed after the
power supply is connected to hoist. Refer to
section 11.0, then proceed with the below
instructions on chain container installation.

Do not overfill chain container.

If chain should overfill and begin to fall, entire
chain container may empty without warning,
resulting in serious personal injury or property
damage.

To assemble chain container to hoist:

1. Hang hoist in position on the I-Beam or trolley.
Do not install chain container yet. Allow slack
side and load side of chain to hang freely from
hoist.

2. Apply power to hoist and press DOWN button
until limit switch is tripped.

3. Mount chain container to hoist undercarriage,
using a short and a long bolt with lock nuts
See Figure 6.

4. Place chain stop into container, and operate
hoist to bring load hook up until upper limit
switch is tripped.

5. Inspect chain to ensure that all non-loaded
chain is completely in container.

Electrical connections must

be made by a qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.

The 230V hoists up to 1-ton are prewired for 3­phase, but can be operated on either single or 3-

phase power supply. (The inverter will convert
incoming single-phase power for proper delivery to
the 3-phase induction motor.)

The 460V hoists and 230V 2-ton and larger hoists,
are 3-phase only.

If an electrical plug (not provided) is installed on
the hoist power cable, it must be appropriate for
the phase used.

The hoist should be connected to a circuit with
current overload protection, rated at 120% of the
full load amperage listed on the hoist’s nameplate.
If fuses are used, they must be time-delay fuses
rated “D”. Local codes take precedence over
recommendations.

11.1 Grounding

In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric shock.

This hoist is not supplied with a power plug. Power
supply cables may either be fitted with a UL/CSA­listed plug rated for the appropriate phase and
voltage, or “hard-wired” directly to a control panel.
If hard-wired, make sure a disconnect is available
for the operator.

If a plug is installed, it must have an equipment­grounding conductor and a grounding prong. The
plug must be plugged into a matching outlet that is

10

properly installed and grounded in accordance with
all local codes and ordinances. Do not modify the
plug – if it will not fit the outlet, have the proper
outlet installed by a qualified electrician.

Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment-grounding connector.

If repair or replacement of the electric cord or plug
is necessary, do not connect the equipment­grounding conductor to a live terminal.

Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to whether
the tool is properly grounded.

Repair or replace damaged or worn cord
immediately.

11.2 Variable frequency drive

The inverter is not user-

serviceable. Any programming or service must
be performed by qualified personnel.

The inverter contains high
voltage elements that may retain a significant
charge for several minutes after power is shut
off.

This hoist uses Variable Frequency Drive, also
called an A.C. Inverter, to provide infinitely variable
speeds within the specified range. The inverter
controls motor speed by varying the frequency of
voltage supplied to the motor. This is especially
useful for slowing a load as it nears drop point.

The inverter does not require any programming; it
has been pre-programmed from the factory. With
the possible exception of the reset button, the

buttons on the face of the inverter should never
be pushed at any time. Use only the controls on

the pendant cord.

If you suspect a problem with the inverter or its
settings, contact JET technical service at 1-800­274-6848.

A lightning strike or power

surge may cause inverter failure. When hoist is
not in use, disconnect power plug, or have a 3­or 4-pole disconnect installed on the power
side.

11.3 Inspecting hoist motion

1. Before closing circuit breaker and testing hoist,

check that wiring has been complete. If hoist
cannot be observed when circuit breaker is
closed, station an observer within sight of hoist
to report any movement when power is
applied. Be prepared to disconnect power if

hoist motor starts when power is applied – the
hoist must remain motionless when power is
applied. Find and correct any problems before
continuing.

2. With no load on load hook, press UP button
very briefly and observe hoist action. The hook
should move upward.

3. On hoists with 3-Phase power supply, if the
hook moves in opposite direction to that shown
on control button, or if no motion occurs when
UP button is pressed, then the power supply
wires are incorrectly positioned.

Disconnect hoist from power, and switch
any two of the three supply wires at the power
source (excluding the ground wire). Do not

attempt to rewire the hoist circuit or
pendant controls for this problem. Use the

same safety precautions when reversing two
of the supply wires as was used when the
wires were originally connected.

4. Reconnect power and test hoist movement
again without load. Run hoist to maximum
lifting height to ensure lift limiting devices are
operating properly. Adjust speed knob
throughout its range to test variable speed
function.

12.0 Pre-operation inspection

12.1 Inspecting load chain

Clean chain with non-acidic solution, and carefully
inspect entire load chain. Replace damaged chain
before using hoist. See section 17.2 for maximum
pitch allowed for chain length. If the chain exceeds
this amount, it must be replaced.

Also replace the load chain if any of the following
are identified:

1. Seriously rusted or cracked.

2. Marks on the chain surface are deeper than
5% of the link’s diameter.

3. Links are twisted or deformed.

4. Links are stretched too long or considerably
worn on the surface, especially at points where
links contact each other.

Never extend load chain by welding a second
piece to the original.

Do not operate hoist with

twisted, kinked or damaged load chain. Do not
splice load chain.

Check that chain does not twist along its length
from hoist to hook. If twist is present on units with
multiple falls, the hook has been capsized; it must
be passed back through the chain loop to remove
all twist in the chain.

11

The load chain supplied with

your JET chain hoist is designed,
manufactured, and tested for proper fit and
durability. Over a period of time, the chain may
need to be replaced. For your own safety, use
factory replacement chain only. Use of other
than factory replacement chain may cause
serious injury and/or damage to hoist.

A light coat of 30W oil applied periodically to the
chain will create easier operation and prolong
chain life.

12.2 Inspecting hooks

It is important to check top and bottom hooks for
proper opening and other signs of deformation or
damage. Replace a hook immediately if any of the
following problems are identified:

1. The safety latch is damaged or bent, or no
longer has sufficient spring pressure to contact
the hook tip.

2. The vertical angle at neck of the hook reaches
10 (see Figure 7).

13.0 Operation

13.1 Controls

Refer to Figure 8.

Allow hoist to come to a full

stop before changing direction. Rapidly
reversing or catching a falling load can
overload the hoist system and cause failure in
hoist and/or chain, resulting in injury or
property damage.

Figure 7

3. Chemical corrosion or cracks on the hook.

4. Excessive wear on the inside surface.

5. The throat opening has enlarged. (See section

17.1 for maximum allowable limits for the
throat opening.)

NOTE: Excessive hook throat opening or twist
indicates abuse or overloading of the hoist. If such
deformation is discovered, inspect hoist, chain and
all supporting members very carefully for additional
indications of excessive hoist loading.

Do not attempt repair of a

hook by heat treating, bending or attaching
anything by welding. Such procedures will
weaken and may cause failure of the hook.

Figure 8

To lift a load, press and hold the UP button. To
lower, press and hold the DOWN button. The
speed dial may be rotated at any time while
pressing one of the other buttons. Use low speed
when beginning to lift a load, or when settling a
load at the drop point.

If hoist is connected to a manual trolley, move hoist
by pushing on the suspended load. Move an
unloaded hoist by pulling on the empty hook. Do
NOT move hoist by pulling on control cord.

Always keep hoist clean, and store in a clean, dry
location.

Avoid lifting one load with two hoists. If this is
unavoidable, apply equal weight to both hoists and
use hoists with proper lift capacity. Capacity of

each hoist must be equal to the total load to be
lifted.

Follow this general procedure for hoisting loads:

1. Secure upper hook to the supporting structure.

2. Place load sling or chain in center of bottom
hook, making sure the safety latch is secure.

Never load the hook in front of the safety
latch. See Figure 9.

12

Figure 9

3. Press UP button and remove all slack in load
chain. Increase tension in load chain until hoist
is about to raise the load.

4. Check again that load is properly slung, is
directly under hoist, and will not suddenly
swing or twist.

5. Raise load an inch or two above ground and
stop. Observe load for a few moments, looking
for signs that load or hoist system is unstable,
or other indications of a problem.

6. Check that chain is not twisted at bottom hook.
All welds should face same direction (see
Figure 13). For hoists with two or more falls of
chain, make sure bottom hook is not capsized.
This may cause the chain to twist.

7. Raise load to traveling height. Raise only to
height necessary to safely clear all obstacles.

8. Lower load at destination. If both UP and
DOWN commands must be used during
lowering, pause for a moment between each
reversal of load direction. Use the variable
speed dial for gradual speed changes when
needed.

9. Slowly allow weight to shift from hoist to
ground or new support. Do not approach load
until all tension is out of chain and load is
stable.

13.2 Thermal overload protection

Figure 20

13.3 Magnetic brake function

The magnetic disc brake provides dependable and
rapid stops, and produces less wear on parts than
standard mechanical braking systems. It also
provides an important safety measure – a power
failure will result in immediate engagement of the
brake. (See section 18.0 for maintenance and
adjustments.)

13.4 Optional pendant controls

The 2-button pendant controls (shown in Table 4)
are replacement parts for the pendant supplied
with the hoist.

The 4-button controls are for use with an optional
JET electric trolley. They possess buttons for both
vertical lift and lateral travel, thus allowing one
pendant control to be used for both hoist and
trolley.

See your dealer or call JET to order.

Table 4

If the hoist has stopped working due to overloading
and tripping of the thermal relay, there are two
methods of resetting the hoist:

1. Lower hoist to operator’s level, open cover on
the inverter end, and push reset button (Figure

10). OR…

2. Shut off power supply to hoist. This will reset
the hoist without having to lower it.

Analyze the possible reason for overloading and
correct it. Make sure load is within rated capacity.

13

14.0 Adjustments

14.1 Replacing load chain

Over time, the load chain will wear or elongate.
This can cause damage to hoist, breakage, or non­engagement of the load sheave. The following
procedures describe replacing the load chain for
single and multiple fall hoists. These procedures

should be performed by qualified persons only.

It is recommended that after installing new chain,
the first few lifts be limited to no more than 25-50%
of rated load capacity. Thoroughly inspect new
chain for twist before placing hoist into routine
service.

14.2 Cutting chain

Use eye/face protection when

cutting chain.

Use a bolt cutter with special cutter jaws for cutting
hardened chain. Cut only one side of the link at a
time. When making the second cut, place a mat
over the chain to catch the flying chain section.

14.3 Making a C-Link

Replacing load chain will require the use of a C-link
(in some cases, two C-links), which you can easily
make as follows:

1. Cut a link from the old chain.

2. Cut the weld from the link leaving an opening
approximately 1.25 times the diameter of the
link material. See Figure 11.

3. Grind the cut areas smooth and remove all
burrs.

away from load sheave (see Figure 13 and its

accompanying text).

Figure 12

5. Keep tension on both sides of the chain and
lower the load hook to pull the new chain
through the hoist. Do not let the chain twist or
bind as it is being pulled through the hoist.

6. Stop hoist when 1 to 2 feet of new chain
remains on the slack side.

7. Install the limit block, spring and chain stop on
the slack end of the chain.

8. Continue lowering the load hook until the new
chain clears the load hook. Inspect condition of
both spring and hook.

9. Lower load hook until the limit switch stops
hoist movement. Inspect the chain for any
signs of twist.

10. Install chain container, making sure to install
the self-locking nut on the screw. Do not fill
chain container by hand.

14.5 Vertical and horizontal links

Vertical and horizontal are determined by the
relationship to the load chain sheave. Vertical links
will be guided by the center slit in the sheave.
Horizontal links will engage the oval pockets on the
sheave. See Figure 13.

Figure 11

14.4 Single fall chain hoist

1. Lower the load hook until only 1 to 2 feet of
slack chain remains in the chain container.

2. Remove chain container.

3. On the slack side of the chain, remove the
chain stop, spring, and limit block (Figure 12).
Keep these handy for later re-installing.

4. Using a C-link, connect the new chain to the
old chain. Be sure vertical link welds face

Figure 13

14

14.6 Dual/multiple fall chain hoists

The link on the load side end

must be a vertical link. If it is a horizontal link,
the chain will have a twist in it.

1. Lower hook until only 1 to 2 feet of slack chain
remains in the chain container.

2. Remove chain container.

3. On the slack side of the chain, remove the
chain stop, spring and limit block (see Figure

12). Keep these handy for later re-installing.

4. Using a C-link(s), connect the new chain to the
old chain. If the end link of the old chain is
horizontal, use two C-links. If the end link of
the old chain is vertical, use one C-link. See
Figure 14. Using the correct number of C-links
will properly orient the chain, and ensure that
the first link on the load side end is a vertical
link.

Figure 14

5. Install the limit block, spring, and chain stop on
the opposite end of the new chain.

6. Support the load hook so that the load chain
can pass through the chain sheaves smoothly.

7. Press the DOWN button to move the chain
through the hoist. Keep tension on the chain
as you pull it through to the load side, until the
C-link(s) clears the hoist at the load side.
Continue pressing DOWN until the new chain
clears the load hook.

8. Place the first link of the new chain into the
load side end holder (Figure 15). Be sure there
is no twisting of chain between last chain
sprocket and load side end holder.

Figure 15

9. Install chain container, making sure to install
the self-locking nut on the screw. Do not fill
chain container by hand.

10. Lower hook until limit switch stops hoist
movement, then raise hook until limit switch
stops hoist movement. Inspect chain for any
signs of twist and correct before continuing.

Note: On the 10-ton hoist, the above procedure is
repeated for each of the 3-ton bodies.

It is recommended that after installing new chain,
the first few lifts be limited to no more than 25% to
50% of rated load capacity. Inspect chain for twist
before placing hoist into routine service.

15

15.0 Inspection and maintenance

All repairs and adjustments are to be performed by qualified persons using

procedures that are approved for the hoist system being serviced. All safety-related deficiencies
discovered in the inspection are to be corrected before hoist is placed back into service. Check for
internal damage whenever external damage has occurred.

Read and follow all relevant ANSI Inspection and Maintenance standards, particularly ANSI/ASME B30.16
Overhead Hoists (Underhung). Know the meaning of Frequent Inspection, Periodic Inspection, Normal Service,
Heavy Service, and Severe Service. It is the customer’s responsibility to understand and follow all ANSI and
JET inspection and maintenance instructions.

The following definitions are based upon ANSI/ASME B30.16.

Normal Service: Operation with randomly distributed loads within the rated load limit or uniform loads less
than 65% of rated load for not more than 25% of the time.

Heavy Service: Operation within rated load limit, which exceeds normal service.

Severe Service: Normal or heavy service with abnormal operating conditions.

Designated Person: A person selected or assigned as being competent to perform the specific duties to

which he/she is assigned.

Qualified Person: A person who, by a recognized degree or certificate of professional standing, or who,
by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or
resolve problems relating to the subject matter and work.

Avoid potential shock hazard. The inverter contains high voltage elements that may

briefly retain charge after powering down. Do not perform any mechanical or electrical maintenance on
the hoist for at least five minutes after hoist is disconnected from power, to allow de-energizing of the
capacitor.

16

16.0 Inspection schedules

The VOLT series Hoist should be given an initial inspection upon installation and prior to use (see also Pre-
Operation Inspection in this manual). Following that, it must be inspected by a designated person at the time
interval noted below. Dated inspection and repair reports must be maintained. Copies of all reports must be
available to service personnel.

Visual inspections are divided into two general classifications based upon frequency, then further categorized
by type of service, as shown below.

More detailed information may be found in ANSI/ASME B30.16 standards publication.

FREQUENT Inspection Schedule

Service Interval:

Normal Service: Monthly
Heavy Service: Weekly
Severe Service: Daily

1. Check oil level in gearbox.

2. Check braking system for slippage.

3. Check that pushbutton controls and variable
speed dial operate properly.

4. Check that limit switches function properly.
Without load, operate UP button control while
observing limit spring. If limit spring becomes
compressed and motor does not stop, STOP
operation immediately. Limit switch is not
operating properly. Repeat test with DOWN
button control.

5. Check top hook and load hook for deformation,
chemical damage, and cracks.

6. Check hook latch operation.

7. Check that load chain is clean and lightly
lubricated, free of excessive wear or
deformation at the contact points between
links and link and hook (see section 17.2 in
this manual). This hoist uses special alloy
hoisting chain and does not interchange with
any other manufacturer. All replacement chain
must be purchased from your JET distributor
or from JET directly by calling 800-274-6848.

8. Check that the chain passes smoothly through
all sprockets while under load.

9. Check entire hoist system for signs of damage
and loss of integrity. Listen for any abnormal
sounds.

Note: In addition to the above inspections of the hoist, it is recommended that the inverter be inspected by a
qualified person at appropriate intervals as designated by the inverter manufacturer, including an insulation
resistance (Megger) test approximately every two years.

PERIODIC Inspection Schedule

Service Interval:

Normal Service: Yearly
Heavy Service: Semi-Annually
Severe Service: Quarterly

1. Perform all of the Frequent Inspection items.

2. Drain and refill gearbox. (See section 10.2.1
for details and capacities.)

3. Check entire unit for loose screws, bolts, nuts,
rivets and pins.

4. Check for evidence of excessive wear,
corrosion, cracks, or distortion in the following
parts: hook parts, chain attachments,
suspension bolts and shafts, housings, gears,
bearings, pins, rollers, and locking and
clamping devices.

5. Check for evidence of damage to hook parts
including hook retaining nuts and collars and
pins, and hook holding frame and parts used
to secure the frame.

6. Check for evidence of damage or excessive
wear of load gear, sheave and sprocket wheel.
If the pockets are too deep, the chain may jam
with corresponding failure of engagement
between chain and sprocket or sheave.

7. Check for evidence of excessive load brake
wear. Inspect clearance between brake
components, and adjust if needed.

8. Check for evidence of pitting or other
deterioration of visible controller contacts.

9. Check for evidence of deterioration of
supporting structures and trolleys.

10. Check for visible deformation of limit switch
coil springs.

11. Check that all warning labels are present and
legible.

17

17.0 Allowable limits

17.1 Hook wear limits (top and bottom)

Replace the hook when the A, B, or C measurements, as shown in Figure 16, reach the limit shown in the
tables below. Never heat-treat the hook or attach anything to the hook by welding.

NOTE: Excessive hook throat opening or twist indicates abuse or overloading of the hoist. If such deformation
is discovered, inspect the hoist, chain and all supporting members very carefully for additional indications of
excessive hoist loading.

Figure 16 Table 5

17.2 Chain wear limits

Carefully inspect the entire load chain. Measure eleven consecutive links with calipers in the manner shown in
Figure 17. Check every three feet and especially where excessive wear is indicated. Any load chain that shows
noticeable deformation or heat influence must be replaced with a new one. Never extend load chain by welding
a second piece to the original.

Figure 17

Table 6

18

18.0 Brake adjustment and maintenance

For normal brake operation, the following requirements must be met:

1. Location altitude must not exceed 2,000 meters (6500 feet) and relative humidity must be under 85%.

2. Brake is free of corrosion or dust.

3. Insulation grade is B, protection grade IP23, and voltage fluctuation remains between +5% and -15%.

4. Surrounding temperature must be between -5 to 40°C (23 to 104°F) and the fricative surface is free
from oil.

5. The air gap must not exceed the maximum limit.

Working principle: The DZS3 magnetic brake is a fricative braking device which automatically engages if there
is a power loss. The brake consists of a magnetic yoke, an exciter coil, springs, a brake lining, and an
armature, a splint sheath, a manual release and fixing bolts. The brake has been installed on the cover plate of
the motor and pre-adjusted to the required gap value.

When electricity passes through the exciter coil, a magnetic field is produced to pull the armature toward the
magnetic yoke, disconnecting the armature and the brake lining to allow the hoist shaft to rotate. When an
absence of electricity occurs, the magnetic field disappears and the armature is released, which results in the
spring pressing against the armature. The armature then asserts a hard pressure on the fricative lining to
produce a braking effect.

Turning the manual release (#5, Figure 18) or tightening the hollow bolt (#2, Figure 18) releases the armature
for adjustment.

Hoist model

Rated braking torque (Nm) 8 20 40

Regular working air gap (mm) 0.3 0.4 0.5

Max. working air gap (mm) 1.0 1.0 1.0

Rated voltage 207 V

18.1 Brake adjustment

Refer to Figure 18.

1. Turn the hollow bolt (2) into the magnetic yoke
(7) to loosen it.

2. Tighten the fixing screws (8) and use a plug
gauge to verify that the air gap meets the
required value.

3. Turn the hollow bolt (2) so that it is fixed on the
flange plate.

1/4T 1/2T, 1T 2T,3T,5T

Table 7

18.2 Periodic maintenance

 The brake lining is wearable and should be

checked every four months to make sure the
air gap remains within normal parameters.

 Check screws regularly to ensure tightness.

 Keep motor fan / brake area clean of dust.
