JLC680-2 Rev AA April 2019

HOIST SAFETY IS UP TO YOU...

DO NOT LIFT MORE THAN RATED LOAD.

CHOOSE THE RIGHT HOIST FOR THE JOB...

Choose a hoist with the capacity for
the job. Know the capacities of your
hoists and the weight of your loads.
Then match them.

The application, the size and type
of load, the attachments to be used
and the period of use must also be
taken into consideration in selecting
the right hoist for the job.

Remember, the hoist was
designed to ease our burden and
carelessness not only endangers the
operator, but in many cases, a valuable load.

DO NOT OPERATE DAMAGED OR MALFUNCTIONING HOIST

DO NOT OPERATE WITH TWISTED, KINKED, OR
DAMAGED CHAIN.

INSPECT

All hoists should be visually inspected before
use, in addition to regular, periodic maintenance
inspections.

Inspect hoists for operations warning notices and
legibility.

Deciencies should be noted and brought to the attention of
supervisors. Be sure defective hoists are tagged and taken out of
service until repairs are made.

Under no circumstances should you
operate a malfunctioning hoist.

Check for gouged, twisted,
distorted links and foreign material.
Do not operate hoists with twisted,
kinked, or damaged chain links.

Load chain should be properly
lubricated.

Hooks that are bent, worn, or whose
openings are enlarged beyond
normal throat opening should not
be used. If latch does not engage
throat opening of hook, hoist should
be taken out of service.

Chains should be checked for
deposits of foreign material which may be carried into the hoist
mechanism.

Check brake for evidence of slippage under load.

DO NOT PULL AT AN ANGLE. BE SURE HOIST AND LOAD ARE
IN A STRAIGHT LINE.

DO NOT USE LOAD CHAIN AS A SLING.

USE HOIST PROPERLY

Be sure hoist is solidly held in the uppermost part of the support
hook arc.

Be sure hoist and load are in a straight line.
Do not pull at an angle.

Be sure load is hooked securely. Do not tip load the hook. Do not
load hook latch. Hook latch is to prevent detachment of load under
slack chain conditions only.

Do not use load chain as a sling. Such usage damages the chain
and lower hook.

Do not operate with hoist head resting against any object. Lift the
load gently. Do not jerk it.

.

DO NOT LIFT PEOPLE OR LOADS OVER PEOPLE

LIFT PROPERLY

Do not lift co-workers with a
hoist.

Make sure everyone is clear of
the load when you lift.

Do not remove or obscure
operational warning notices.

MAINTAIN PROPERLY

CLEANING

Hoists should be kept clean and free of dust, dirt, moisture, etc.,
which will in any way affect the operation or safety of the equipment.

LUBRICATION

Chain should be properly lubricated.

AFTER REPAIRS

Carefully operate the hoist
before returning it to full service.

Violations of any of the warnings listed may result in serious
personal injury to the operator or nearby personnel by nature
of released load or broken hoist components.

1-3 BASIC HOIST DATA

The basic hoist models covered by this manual are listed in
Table 1.

To avoid personal injury:

Do not use the equipment shown in this manual to lift, support, or
otherwise transport people, or to suspend unattended loads over
people.

1-2 SAFETY STANDARDS

All persons concerned with the installation, operation, inspection
and maintenance of these hoists are urged to read ASME B30.16.
That Standard contains valuable guidelines concerning practices
designed to minimize hazards associated with the use of overhead
hoisting equipment. ASME B30.16 also contains detailed procedures
for establishing hoist inspection and maintenance programs and can
be of signicant assistance in maintaining compliance with OSHA
regulations.

1. Follow all local electrical and safety codes, as well as the
National Electrical Code (NEC) and the Occupational Safety
and Health Act (OSHA) in the United States.

2. Hoist must be securely and adequately grounded. Hoist
power cable is provided with an additional lead (green) for
grounding purposes.

Always disconnect power source before working on or near
a hoist or its connected load. If the power disconnect point
is out of sight, lock it in the open position and tag to prevent
unexpected application of power.

3. Be careful when touching the exterior of an operating motor;
it may be hot enough to be painful or cause injury. With
modern motors this condition is normal if operated at rated
load and voltage (modern motors are built to operate at higher
temperatures).

4. Protect the power cable and control cable from coming in
contact with sharp objects.

5. Do not kink power cable and control cable and never allow the
cable to come in contact with oil, grease, hot surfaces,
or chemicals.

6. Make certain that the power source conforms to the
requirements of your equipment.

7. Inspect the unit daily before operating the hoist.

8. Cluttered areas and benches invite accidents.

9. The operator should not engage in any practice which will
divert his attention while operating the hoist.

1-4 APPLICATION INFORMATION

JLC680-2 Rev AA April 2019

SECTION II — SPECIFICATIONS

Cofng JLC series electric chain hoists are rugged, portable hoists
that provide quick, precise lifting. The hoists are constructed of
tough, but lightweight, die cast aluminum alloy housings. An oil bath
transmission, equipped with heat-treated, alloy steel gears and an
overload limiting clutch, provides smooth and reliable operation.
With a pushbutton station that ts comfortably in one hand, the
operator can safely control the hoist while the other hand is free to
guide the load. The electrical controls use a low voltage circuit (24V
standard, 115V optional). Terminal blocks allow for easy voltage
conversions on dual-voltage models.

Other features that ensure the safe operation of Cofng electric
chain hoists include a magnetic disc brake that delivers sure
stopping and secure holding of the load. Adjustable upper and lower
limit switches regulate the load travel. As a standard, hooks are
supplied with safety latches. For additional safety, a chain stop is
attached to the slack end of the load chain.

Cofng electric chain hoists are designed and tested in accordance
with the American Society of Mechanical Engineers Code
B30.16, “Safety Standard for Overhead Hoists.” Hoists are built in
compliance with CSA, le number LR 44484. Made in U.S.A.

NOTE: The above data is the nominal motor current at full load.
At full load, it is not unusual for the hoist to draw in excess of the
values listed when lifting. It is critical to ensure that the voltage at
the reversing contactor does not drop more than 10% below the
nominal voltage while lifting a load. Low voltage will result in higher
amp draw, damage to the hoist, and potential re hazards. Cofng

Failure to comply with Safety precautions outlined throughout
this manual can result in serious injuries or death. Before using
this hoist, each operator should become thoroughly familiar with
all warnings, instructions and recommendations in this manual.

SECTION III — INSTALLATION

1. Before installing the hoist, check the following:
a. Make sure all supporting structures and attaching devices

are strong enough to hold your intended loads. If in doubt,
consult a qualied structural engineer.

b. Provide proper branch circuit protection for the hoist as

recommended in the National Electrical Code.

c. The power supply should be plus or minus 10% of the

voltage specied on the motor nameplate. It is critical to
use adequate sized power cables, especially with 1- phase
hoists (See Table 5, page 11). Be sure dual voltage hoists
are connected or wired to correspond with your power
supply (See WIRING, page 9).

d. Installation area must provide operating conditions for the

operator including sufcient room for the operator and
other personnel to stand clear of the load at all times.

e. For installations where the slack chain hanging from the

unit may be objectionable or hazardous, the use of a chain
container is recommended (See CHAIN CONTAINER,
page 5).

2. JLCET models come with a Cofng ETB push-type trolley and

an adaptable suspension lug. ETB trolleys are made to run
on American Standard I-Beams and Wide Flange Beams with
ange widths up to 8". For assembly refer to the instructions
provided with the trolley. The hoist lug must be centered
with the sideplates (±1 washer). Due to the lug thickness, the
washer placement between each sideplate and the lug may
differ by 1 less washer than the generic instructions specify. For
installations where the trolley can not be slid onto the end of a
beam, leave the load pin nuts loose enough to get the wheels
around the beam ange. Check the ange width setting before
tightening the nuts to 125 ft-lbs. Be sure to have end stops on
your beam.

3. Before operating the hoist, be sure to observe the following:

a. ALWAYS DISCONNECT HOIST FROM POWER SUPPLY

before removing electrical cover or when making any
electrical connection in the hoist or pushbutton station.

b. The ground wire (green colored) of the power cable should

always be connected to a suitable ground by means of
a screw or clamp. An alligator clip does not make a safe
ground connection.

c. When installing a three-phase hoist, make only temporary

connections at the power source. Push the “UP” button
and observe the direction of the load block. If it raises, the
phasing is correct and permanent connections may be
made at the power source. If the load block lowers when
the “UP” button is pushed, release the button immediately
since the limit switches will not operate to protect the hoist
from over-travel. Reverse any two wires (except the green
ground wire) at the power source to correct the load hook
direction (phasing). Do not change connections in the hoist
or pushbutton assembly.

d. Make sure load chain is not twisted as it travels into

the hoist.

e. Operate hoist in a hanging position only. Hoist should

be permitted to align itself for a straight line pull. Do not
attempt to pull around corners.

f. Read ASME-B30.16 Safety Code for Hoists.

4. Lubricate the chain as necessary, see LUBRICATION, page 9.

5. Check the function of the limit switches. Before placing hoist in

operation, check limit switch settings. Operate pushbutton until
near stop point and inch into stop limit, both top and bottom. If
either switch is not correct, adjust according to LIMIT SWITCH
ADJUSTMENT, page 8.

JLC680-2 Rev AA April 2019

CHAIN CONTAINER (OPTIONAL ACCESSARY)

Refer to Table 4.
For installations where the slack chain hanging from the hoist

may be objectionable or hazardous, the use of a chain container
is recommended.

Available chain containers include the standard containers designed
for lifts of up to 50 ft on single-chained hoists and 25 ft on double­chained hoists. For longer lifts, the JLC927-4 container is available.
For applications where a fabric bag is preferred, the JLC927-20F,
JLC927-35F and the JLC927-50F are all options.

Do not attempt to store more chain in chain container than
that specified in the table below. Failing to do so may cause
serious hoist damage and hazardous conditions that may
result in injury or death.

Instructions are provided with each of these chain containers and
must be adhered to closely to ensure a proper installation. To install
the long lift chain container or a fabric chain container, you must follow
instruction sheets provided with the chain container. The following
instructions are for the standard JLC927-1 chain container only..

INSTALLATION OF STANDARD CHAIN
CONTAINER (JLC927-1)

Refer to Figure 1.

1. Remove retaining clip and attachment pin and let the slack
chain hang free.

2. Run load hook down to its lowest position. Place the slack end
of chain in chain container. Do not remove the chain stop.

3. Place chain container ush against housing with chain stripper
between top lugs. Insert long attachment pin and replace

retaining clip.

4. Feed the remainder of chain into container by operating hoist in
the “UP” direction to the top limit. This will permit the chain to
pile freely and prevent the chain from kinking, which may occur
if the chain is placed in the container by hand.

Figure 1 — Installing Chain Container Assembly

Load chain that is kept clean and lubricated is essential to the
safe operation of a hoist with a chain container. Failure to do
so may cause serious hoist damage, spillage of chain from
container, cross-linked chain resulting in dropped load and
other hazardous conditions that may result in injury or death.

SECTION IV — OPERATION

4-1 GENERAL

This hoist is designed for safe operation within the limits of its rated
capacity. It is controlled by the “UP” and “DOWN” buttons of the
pushbutton station. Two-speed models utilize 2-step buttons, the
rst step for operating the slow speed and the second for the fast
speed. Although the Cofng JLC is built with many features to
ensure safety, it is a requirement that a hoist operator understands
safe lifting practices. The following points must be observed.

Do not allow load to come in contact with the chain container.
If this situation exists reset the “UP” limit switch so that the
hook block stops below the chain container (See LIMIT SWITCH
ADJUSTMENT, page 8).

1. Do not overload the hoist.

2. Do not make extreme side pulls with the hoist.

3. Operate the hoist only in a hanging position with
adequate support.

4. Do not “sling” the load hook and chain around the load.
Use an approved sling.

5. Be sure there are no twists in the load chain as it travels into
the hoist housing. This condition should be constantly checked
on double chain hoists because it is possible for the load block
to be “capsized” or turned over one or more times.

6. Before raising a load, always check to see that it is held
securely in the hook or sling chains, etc. Raise the load only
until the load chain is taut and then double check the rigging
before continuing to raise the load.

7. Do not stand beneath a load! Do not move a load in such
a manner as to endanger personnel.

SECTION V — MAINTENANCE

5-1. INSPECTIONS

A planned inspection routine should be established for this hoist
based upon frequency of use, severity of use, and environmental
conditions (Reference ASME Standard B30.16). Some inspections
should be made frequently (daily to monthly) and others periodically
(monthly to yearly). It is strongly recommended that an Inspection
and Maintenance Check List and an Inspector’s Report, similar
to those shown in Figures 10A and 10B, be used and led for
reference. All inspections should be performed or overseen by a
designated inspector. Special inspections should be made following
any signicant repairs or any operating occurrence leading one to
suspect that the hoist’s capability may have been impaired

5-2. LOWERING WITHOUT POWER

If the power fails with a load suspended, the hoist will automatically
stop. In an emergency the load can be lowered without power as
follows:

1. DISCONNECT HOIST FROM POWER SUPPLY AND REMOVE
ELECTRICAL COVER.

2. Refer to Figure 5. Open disc brake manually by using two
screwdriver blades, one on each side of the brake at a
point close to the brake spring posts. Apply pressure to the
underside of the armature plate (points “X”) to close the
solenoid and release the brake.

3. Use several quick releases instead of holding brake open
continuously. Do not exceed normal lowering speed.

Do not allow screwdriver blades to touch rotating friction
disc “C”.

To avoid personal injury:

Do not use the equipment shown in this manual to lift, support, or
otherwise transport people, or to suspend loads over people.

8. Don’t lower into areas where visibility is obscured unless
someone else is guiding the operation.

9. Use common sense at all times when operating a hoist.

10. Do not operate if direction of hook travel is not the same as
indicated on button being pushed.

11. Do not operate unless hook travel limit devices function. Test
without load each shift.

12. Do not operate when hoist is not centered over load.

13. Do not operate if chain is not seated properly in sprockets or
sheave grooves.

14. Do not operate damaged or malfunctioning hoist.

4-2. OVERLOAD LIMITING PROTECTION

This hoist is equipped with a factory-calibrated overload limiting
clutch that will permit the lifting of loads within its rated capacity,
but will prevent the lifting of damaging overloads while the hoist is
being operated. If the load being lifted exceeds the lifting capability
of the overload clutch, the hoist motor will continue to run, causing
overheating of both the clutch and hoist motor. This condition should
be avoided by immediately releasing the “UP” button and reducing
the load to within the rated capacity of the hoist. See GEARING,
page 10, for additional instructions on this device.

The overload limiting clutch is an emergency protective device and
should not be used to measure the maximum load to be lifted, or to
sense the overload imposed by a constrained load. While the overload
limiting clutch will protect the hoist from damaging overloads, it will not
ensure that a load is within the rated capacity of the hoist.

Do not allow the load to descend rapidly. This causes the motor
to race and serious damage may result.

5-3. HOOKS

Refer to Figure 2.

1. Inspect hooks once daily for cracking, extreme wear or
spreading. Replace hooks showing any of these signs. If
the throat openings are spread wider than the maximum
permissible 15% increase listed here, the hooks have been
overstressed and must be replaced. Any hook that is bent or
twisted more than 10 degrees from the plane of an unbent hook
must also be replaced.

2. The hook latches should be inspected to ensure that they
close the hook throat opening in a secure manner when a load
is applied. Inspect the hook shank and nut for any stripping
of the threads or other damage. The hook nut should be fully
restrained by the retaining pin.

3. In addition to above, load hooks should be inspected for cracks
by the magnetic particle, dye penetrant or other suitable crack
testing inspection method. This should be done at least once
a year.

5-4. CHAIN

Chain inspection and lubrication are the most important aspects of
hoist maintenance. Chain is to be kept clean and lubricated (See
LUBRICATION, page 9) at all times. Visually check the chain every
time the hoist is used. Hoist must not be operated when the chain is
twisted or kinked. Chain inspection will not usually require removal
of the chain from the hoist, but the chain should be run through the
hoist enough so that every link is made visible for inspection.

Load chain that is kept clean and lubricated is essential to the
safe operation of a hoist. Failure to do so may cause serious
hoist damage, spillage of chain from chain container (when
equipped). cross-linked chain resulting in dropped loads
and other hazardous conditions that may result in injury or
death. Chain contaminated with foreign substance must be
removed from service, cleaned and lubricated before hoist
use can continue.

a. Check each link for gouges, nicks, weld splatter, corrosion,

and distortion.

b. Inspect each link for wear to the diameter of the link. The

nominal link diameter is 0.281 inch. If the diameter of any
link of 0.281 chain is worn to less than 0.225 inch, the entire
chain must be replaced.

c. 1. Check the chain for overall wear or stretch by selecting

an unworn, unstretched length of chain (at the slack end,
for example). Let the chain hang vertically with a light load
(about 20 pounds) on the chain to pull it taut. Use a large
caliper to measure the outside length of a convenient
number of links (about 12 inches). Measure the same
number of links in a used section of chain and calculate the
percentage increase in length of the worn chain.

2. If the length of the worn chain is more than 1-1/2%
longer than the unused chain (0.015 inch per inch of chain
measured), then the chain should be replaced. If the chain
is worn less than 1-1/2%, check it at several more places
along its length. If any section is worn more than 1-1/2%,
the chain should be replaced

d. The chain used in the hoist is accurately calibrated to

operate over the load sprocket and is very carefully heat
treated for maximum wear life and strength.

Do not weld or join hoist load chain.
Do not substitute another manufacturer's chain in this hoist.
Damage or wear, beyond the stated limits, to any portion of
the chain requires that the entire length of chain be replaced.

CHAIN REPLACEMENT WITH CHAIN IN HOIST

Refer to Figures 3 & 4.

1. Run hook up to its top limit.

2. DISCONNECT HOIST FROM POWER SUPPLY and remove the
electrical cover.

3. Using a screwdriver, pry the spring guide plate out of the slots
in the limit switch nuts (See Figure 3). Turn the gold nut back to
about the center of the threaded screw. Do not disconnect the
wires from the limit switches.

4. Remove the load block assembly from the old chain. On
double-chained hoists detach the chain from the chain support
and pull it through the load block assembly (See Figure 4).

5. Make a “C” shaped chain link by grinding through the end link
on the load end of the old chain.

6. Using the “C” link, attach the new chain to the load end of the
old chain. Be sure that the welds of the upstanding links of the
new chain will face outward from the load sheave. The end links
must be oriented for attachment to the dead-end attachment
pin and the chain support (double-chained only) without any
twist in the chain. (See Figure 23)

7. With the electrical cover off, connect the hoist to the power
supply. Be sure that the green ground wire is properly grounded
(See INSTALLATION 3b, page 4).

8. Carefully jog the “UP” button and run the joined pieces of chain
into the hoist until about 15" of the new chain comes out the
other side.

9. DISCONNECT HOIST FROM POWER SUPPLY.

10. Remove the “C” link and the old chain. Remove the chain
stop by prying off its retaining ring with a athead screwdriver.
If attached, remove the old chain from the chain stripper by
removing the retainer clip and attachment pin.

11. Attach the chain stop to the slack end of the new chain by
capturing the 12th link with the two stop halves positioned with
their tapered ends pointing towards the hoist. Slide the sleeve
over the halves and attach the retaining ring. If you are not
using a chain container, attach the slack end of the new chain
to the side of the hoist using the attachment pin and retainer
clip. DO NOT allow twists in the chain.

12. Adjust the lower limit switch (See ADJUSTING LOWER LIMIT,
page 8).

13. Attach the bottom block on single-chained hoists using a
new load block pin (See Figure 23). On double-chained hoists,
feed the chain through the load block (welds of the upstanding
links will be in towards the sheave) and fasten the end of the
chain to the chain support using a new chain support pin
(See Figure 23). Be sure there are no twists in the chain.

14. Adjust the upper limit switch (See ADJUSTING UPPER LIMIT,
page 8).

Figure 3 — Limit Switch Assembly

JLC680-2 Rev AA April 2019

Figure 4 — Chain Replacement Diagram

CHAIN REPLACEMENT WITH NO CHAIN IN HOIST

Refer to Figure 4.

1. DISCONNECT HOIST FROM POWER SUPPLY and move hoist
to a work table. Remove the electrical cover, electrical panel
and the electric brake assembly.

2. Detach the chain stripper from the bottom of the hoist.

3. Insert the new chain between the load sheave and the chain
guide. Feed the chain into the hoist by manually turning the
brake hub adaptor. Allow about 15" of chain below the hoist
on the slack end. Be sure the welds of the upstanding links are
out away from the load sheave and that proper orientation is
observed for attachment of the slack end. Also be sure the load
hook assembly (if already attached to the chain) is toward the
center of the hoist or to your right looking from the motor end.

4. Reinstall the chain stripper (with the chain support on double­chained hoists, See Figure 4) observing proper chain alignment
and avoiding any twist in the chain.

5. Follow steps 11 through 14 in previous section, CHAIN
REPLACEMENT WITH CHAIN IN HOIST, to complete the chain
replacement procedure.

NOTE: Inspect chain guides and load sheave for wear, replace as
needed.

“clicks” then turn two slots farther. Release the spring guide
plate and be sure it slips back into the slots in both limit
switch nuts. Do not disturb the silver slotted nut if it has
been set previously.

ADJUSTING LOWER LIMIT (SILVER NUT)

Refer to Figure 3.

1. Suspend the hoist. Carefully lower the load block to a point
where the slack-end loop of the chain hangs down 6" or more
from the hoist housing (or the limit desired in any particular
application allowing the minimum 6"). There should be a
minimum clearance of 1-1⁄2" between the chain stop and
bottom of hoist.

2. DISCONNECT HOIST FROM POWER SUPPLY and remove the
electrical cover.

3. With a screwdriver, pry the spring guide plate out of the slots in
the limit switch nuts.

4. Turn the slotted silver nut toward its limit switch until the switch
“clicks,” then turn two slots farther. Release the spring guide
plate and be sure it slips back in the slots in both limit
switch nuts. Do not disturb the gold slotted nut if it has
been set previously.

CHECK BOTH UPPER AND LOWER LIMITS

1. Connect the hoist to the power supply. Be sure the green
ground wire is properly grounded (See Installation 3-b, page 5).

2. Check load hook direction (See Installation 3-c, page 5).

3. Carefully raise load block to upper limit and observe if it stops
automatically at desired level. Do not allow load block to run
into hoist housing — this will damage the hoist. Maintain a
minimum clearance of 2" from the hoist housing and the top
of the load block on single-chained models and 1" from the
chain support to the top of the load block on double-chained
models.

4. Carefully lower load block to lower limit and observe if it stops
automatically at the desired level. Do not allow slack-end loop
of chain to become taut against hoist housing. This will damage
the hoist. There should be a minimum clearance of 11⁄2"
between the chain stop and the bottom of the hoist.

5. If upper and lower limits operate satisfactorily, hoist is ready for
use. If they are not as desired, repeat adjustment.

5-5 LIMIT SWITCH ADJUSTMENT

IMPORTANT: Before placing hoist in operation, check the limit
switch adjustment. Limit switches are provided to protect the hoist
against damage resulting from overtravel or to allow setting the hook
travel within the factory-set limits of travel. The standard limit switch
is designed for lifts of 50 ft or less on single-chained hoists and 25 ft
or less on the 2 ton, double-chained models. The long lift limit switch
allows for the maximum amount of lift, which is 143 ft on the 1 ton
and under models, and 71 ft on the 2 ton models.

The upper and lower limit switch adjusting nuts are color-coded
gold and silver respectively. Each limit nut has 10 slots for ne
adjustment, and the increment of adjustment is such that one slot is
equivalent to approximately one link of chain travel with the standard
limit switch. Movement of the limit switch nuts toward or away from
each other decreases or increases the hook travel respectively.

ADJUSTING UPPER LIMIT (GOLD NUT)

Refer to Figure 3.

1. Suspend the hoist. For single chain models raise the load
block until there is a minimum clearance of 2" from the hoist
housing and the top of the block. Double chain models require
a minimum clearance of 1" from the chain support to the top of
the load block.

2. DISCONNECT HOIST FROM POWER SUPPLY and remove the
electrical cover.

3. With a screwdriver, pry the spring guide plate out of the slots in
the limit switch nuts.

4. Turn the slotted gold nut toward its limit switch until the switch

If the wires running to the limit switches are ever disconnected
for any purpose, be sure to replace wires in accordance with the
correct wiring diagram (See Figures 9A, 9B, 9C & 9D).

5-6 BRAKE

Properly adjusted, this brake will release promptly when energized.
It is capable of both smoothly stopping and securely holding the
rated capacity of the hoist. If the hoist develops either undesirable
over-travel after the pushbutton is released (this condition is most
noticeable in the lowering direction) or hesitates to lift the load
promptly when the pushbutton is depressed (this condition is most
noticeable in the hoisting direction), the brake should be adjusted.

BRAKE ADJUSTMENT

Refer to Figure 5.

1. DISCONNECT HOIST FROM POWER SUPPLY and remove the
electrical cover.

2. With reference to Figure 5, the gap between the brake
armature “A” and the eld “B” should be checked. The
correct gap is 0.015". Adjustment should not be necessary
until gap reaches 0.040".

3. Adjust the gap using a 9/16" wrench on the 3 locknuts “F”.
Check with a feeler gauge to be sure the gap is the same on
both ends of the solenoid.

4. Adjustment is now complete and the brake properly set.
Replace the electrical cover, reconnect the power supply,
and check hoist brake action.

JLC680-2 Rev AA April 2019

Figure 5 — Brake Assembly

Be sure the bottom of the armature "A "does not bear against
the splined adapter “H”. As adjustments are made, the built­in clearance will be reduced. When this clearance is gone
REPLACE BRAKE DISCS. Minimum allowable disc thickness is
.162".

5-7 HOIST CONTROLS

Both the pushbutton and the reversing contactor are mechanically
interlocked to prevent shorting the circuit and causing serious
damage. As part of maintenance, always check for proper closure
of contact points as well as for burned contacts. If replacement is
necessary, see Figures 16, 17, 18, and 19 for replacement parts.

5-8 WIRING

Refer to Figures 9A, 9B, 9C & 9D.
Single-phase units (115/230V) are shipped wired for 115V and

the 1-speed, 230/460V-3 phase units are wired for 460V unless
otherwise specied when ordered. Hoists wired for other voltages
and 2-speed units are single voltage only. Conversion of dual­voltage hoists to either the higher or lower voltage can be done
simply and quickly as follows:

1. DISCONNECT HOIST FROM POWER SUPPLY and remove the
electrical cover.

2. Each dual-voltage hoist has a terminal block assembly for the
interconnection of the electrical components of the hoist. To
convert the voltage, reconnect the leads to the terminal blocks
according to the wiring diagram located inside the electrical
cover or Figures 9A, 9B, 9C and 9D.

DO NOT move any wires or make any changes to the
electrical circuit except at the terminal block assembly.
Tug on wires to ensure they are securely connected.

3. After converting the voltage, recheck phasing and limit switch
operation (See INSTALLATION 3-c & 5, page 5).

IMPORTANT: Always refer to the wiring diagram located on the
inside of the electrical cover or Figures 9A, 9B, 9C and 9D when
performing electrical repairs. Make sure all connections are secure
and check for damaged insulation. It is also imperative that the
power circuit has conductors of adequate size (See Table 5).

5-9 LUBRICATION

Refer to Figure 11.
Proper lubrication is necessary for a long and relatively trouble-free

hoist operation. Refer to the following and the RECOMMENDED
LUBRICATION SCHEDULE for lubrication points, type of lubricant,
and frequency of lubrication.

oil level ll plug from the side of the hoist. With the hoist hanging
level, gear oil should be even with the hole. Change oil periodically
depending on the severity of the application and the environmental
conditions (at least every 200 hours of run time).

BEARINGS

All bearings except hook and idler sheave bearings are lubricated
at the factory and should not require additional lubrication. Noisy or
worn bearings should be replaced.

LIMIT SWITCH SHAFT

Remove any dirt accumulation and spray with a general purpose
lubricant.

HOOK BEARING

Apply a few drops of SAE 30 Wt. gear or motor oil around the edge
of the bearing.

IDLER SHEAVE BEARING (BUSHING)

Disassemble load block and apply a light coat of NLGI #2 grease, or
equivalent, inside of bearing.

5-10 HOIST REPAIRS

1. For major repairs or when the hoist is to be sectioned in the
suspension area, it will be necessary to move the hoist to a
workbench or table.

2. For repairs which can be done by removing the electrical cover
only, the hoist need not be moved. Lowering the hoist to a
convenient working level is desirable.

NOTE: If you do not have an experienced mechanic to do your
repair work, we recommend that you send your hoist to an approved
service station for repairs. Use authorized repair parts only.

Remove load and disconnect hoist from power supply before
starting to do any repairs or to take any sections apart.

The following repair instructions will help you in understanding repair
procedures, when related to the Replacement Parts List starting on
page 21. For clarity these are broken down into areas.

ELECTRICAL PARTS AND BRAKE

1. Refer to Figures 15, 16 and 17. Remove the cover to access
the controls. Single-phase models also have a starting switch
and capacitor mounted on the panel as shown in Figure 16.
The terminal blocks and end clamps snap off of the rails on the
panel plate using a small screwdriver. DO NOT SLIDE THE END
CLAMPS. The reversing contactor can be slid off the rail, but it
must be snapped on. Where the contactor ts the rail, one side
has springs or pads that apply pressure against the edge of the
rail. By pressing against that side at the base of the contactor,
you can snap the part on or off using a rotating action. Note the
numbers that label the terminals on the contactor and orient the
part as shown in Figures 9A-9D. Single-phase contactors have
a small jumper that is not present on the 3-phase (note the 3
and 5 terminals on the reversing contactor in Figure 9A).

2. Remove the electrical panel by removing the stand-off screws
(See Figures 16 & 17). The limit switch and brake are now
accessible as shown in Figure 6.

LOAD CHAIN

Clean the load chain with acid-free solvent and coat with SAE 90 Wt.
gear oil. Wipe excess oil to prevent dripping. Never apply grease to
the chain.

GEARING

The gear case of this hoist is lled at assembly with approximately
2 pints of SAE 90 Wt. EP gear oil. Check oil level by removing the

5-11 POWER CORD PRECAUTIONS WITH
1-PHASE HOISTS

Electric hoists require a sufcient power supply. It is especially
important with single-phase voltage to ensure that the conductors
running to the hoist from the power source are adequate in
size to handle the power requirements of the hoist. Inadequate

power cables and branch circuits will cause low voltage, high
amperage, damage to the hoist, and potential fire hazards.

Such problems can be minimized by using 230V power on 115/230V
hoists. The following are recommendations for the conductor gage
size depending on the length, horsepower, and voltage.

SECTION VIII — INSPECTION

INSPECTION

To maintain continuous and satisfactory operation, a regular
inspection procedure must be initiated to replace worn or damaged
parts before they become unsafe. Inspection intervals must be
determined by the individual application and are based on the type
of service to which the hoist will be subjected. The type of service
to which the hoist is subjected can be classied as “Normal”,
“Heavy”, or “Severe”. Normal Service: Involves operation with
randomly distributed loads within the rated load limit, or uniform
loads less than 65 percent of rated load for not more than 25
percent of the time.

HEAVY SERVICE:

Involves operating the hoist within the rated load limit which
exceeds normal service.

SEVERE SERVICE:

Normal or heavy service with abnormal operating conditions or
constant exposure to the elements of nature. Two classes of
inspection - frequent and periodic - must be performed.

FREQUENT INSPECTIONS:

These inspections are visual examinations by the operator or other
designated personnel. Records of such inspections are not required.
The frequent inspections are to be performed monthly for normal
service, weekly to monthly for heavy service, and daily to weekly for
severe service, and they should include those items listed in Table 7.

PERIODIC INSPECTIONS:

These inspections are visual inspections of external conditions by
an appointed person. Records of periodic inspections are to be
kept for continuing evaluation of the condition of the hoist. Periodic
inspections are to be performed yearly for normal service, semi­annually for heavy service and quarterly for severe service, and they
are to include those items listed in Table 8.

CAUTION: Any deficiencies found during inspections are to
be corrected before the hoist is returned to service. Also, the
external conditions may show the need for disassembly to
permit a more detailed inspection, which, in turn, may require
the use of nondestructive type testing

PREVENTATIVE MAINTENANCE

In addition to the above inspection procedure, a preventive
maintenance program should be established to prolong the useful
life of the hoist and maintain its reliability and continued safe use.
The program should include the periodic and frequent inspections
with particular attention being paid to the lubrication of the various
components using the recommended lubricants (see Figure 11).
