suggested distance is at least 1.5 times length of hoist’s chain. Broken or loose chain may cause injuries or death.
• Check hoist and chain are properly lubricated.
• Secure electric chain hoist to a suitable support.
• Visually inspect all electric chain hoists in addition to regular and maintenance inspections
• Refer to maximum load capacity displayed on ID plate of hoist, not capacity of hook.
• Stop operation immediately if unauthorized personnel enter working area.
• Check state of hoist: If engine gets too hot, stop hoist and let it cool for a while.
• Stop, check, and secure load if hoist stops or loses movement during operation.
• Focus on operation. Pay attention at all times and keep proper balance.

dent.
GENERAL ENVIRONMENTAL PRECAUTIONS
WARNINGS
Do not exceed the operating temperatures for
which the hoist is designed. This is stated in this
manual and may vary depending on the model.
When exposed to water, sand, corrosive envi-
ronment and / or Other potentially harmful

It’s the special electrical installation of con-
trolling the circuit not work in case of wirring
error in the power supply.
The limit switch will cut o the motor cir-
cuit and prevent the damage to hois struc-
ture and load chain when over-lifting or
over-lowering happens.
Electric brake is designed for easy access
and simple adjustment. It allows instant
brake as soon as the electric power is cut
o. Thus the braking safety while loading is
guaranted.
Light aluminum alloy shell, light but hard.
The cooling n is specially designed to en-
sure quick heat dissipation with the rate up
to 40% and continuous service.
Increasing the number of load sheave pock-
ets helps relieve vibrations produced by
revolving polygonal sheave on the hoist’s
body and load chain.

are available for long lift applications.
Canvas chain containers is a standard t-

The length of the control is 4 feet less
than the lifting height, which allows it to
be easily operated from ground-level. An
optional wireless remote control is avail-
able for extra convenience.

• Apply lubricant to areas of load chain (shaded areas in gure below) that contact load sheave.
• Hooks and Suspension Components
• Hooks and bearings should be cleaned and lubricated at least once per year for normal usage.
• Clean and lubricate more frequently
• for heavier usage or severe conditions.
• Suspension pins should be lubricated at least twice per year for normal usage; more frequently
for heavier usage or severe conditions.
For dusty environments, it is acceptable to substitute a dry lubricant.

Load Chain
Do not allow chain to run dry.
Lubricant greatly increases life of load chain. Weekly lubrication and cleaning is satisfactory, but under hot, dirty, and ex-
treme conditions it may be necessary to clean chain at least once a day and lubricate it several times between cleaning.
Apply sucient lubricant to obtain natural runo and full coverage, especially in interlink area.
Apply Lubriplate® Bar and Chain Oil 10-R or equal lubricant. Machine or gear oil (grade ISO VG 46 or 68 oil or equivalent)
may be used as an alternative lubricant but must be applied more frequently.

•Lock-out and tag-out the main disconnect switch in ed-energized position before performing any service on hoist.
•Customer must provide power supply cable, fuses, and main disconnect switch.
•Check supply voltage is same as nameplate voltage on hoist.
•Check voltage does not vary by more than ±10% from nominal value.
•Do not use conductors smaller than those listed in this User Manual to supply power to hoist.
•Never bypass limit switches, remove limit switch stops, or alter limit switch devices.
•Check the electric installation and wire gauge selection at www.prowinch.com and follow thesesimple steps)

• Does not meet legal age requirements.
• Has visual or hearing impediments.
• Experiences mental, heart, or other illnesses that could interfere with safe operation of equipment.
• Has not been trained for use of hoist.
• Has not received User Manual for exact equipment.
• Has not demonstrated qualications through a practical operation of hoist.
This hoist must not be operated by someone who:
Install Trolley Into Beam (models with trolley)
1. Install trolley at end side of beam and slip trolley which has already been connected with hoist to
the appropriate place. This is the preferred method.
2. If rst method is unavailable:
• Unload brake stopper from hole A on suspension pin,
and insert it into hole Insert cotter pin again and bend it
completely.
• Pull side plate S and G outside, then lift trolley until
orbit wheel and orbit surface are in same horizontal posi-
tion. Put orbit wheel of side plate G onto surface of orbit.
• Hold side plate G and stop it from dropping from
orbit. Firmly push side plate S and put its orbit wheel onto
surface of beam.
• Unload brake stopper from hole B and insert into hole
A. Do not forget to bend cotter pin.

Handling Precautions
ALWAYS:
NEVER:
• Keep hoist in good condition and make sure chain is lubricated and free to operate.
• Make sure electrical connection is grounded.
• Make smooth movements; avoid sudden changes of directions.
• Check functions of hoist and trolley without any load before operation.
• De-energize equipment after using it to avoid unintentional operation.
• Keep everyone a distance of at least 1.5 times the length of chain. If load falls it can cause serious injuries and
death.
• Make sure no one is beneath load.
• Use pulleys or other accessories that are not specically approved for relevant hoist model.
• Hoist load with tip of hook.
• Hoist load which is not vertical to hook.
• Use hoist to pull or drag load.
• Exceed maximum capacity of hoist.
Recommended Operation
1. Press button lowering unloaded hook down until limit spring touches limit switch. Be sure hoist stops auto-
matically before totally compressing spring.
2. Press button hoisting unloaded hook up until limit spring touches limit switch. Be sure hoist stops auto-
matically before totally compressing spring.
3. Test correct function of emergency stop button. When pressing button , press emergency stop button.
Ensure hoist stops immediately after pressing emergency stop switch. Hoist should not start again if any other
movement button is activated.
4. Rotate emergency stop switch clockwise to original position. When it bounces back, hoist can be started again.
If any of the above tests fail, unit must remain out of service, lockout/tagout power and request maintenance autho-
rized personnel to check circuit layout for automatic locking emergency stop switch.
5. Check lubricating condition of load chain (load chain has been lubricated before delivery, but could be dried in
transportation). Apply lubricant into chain bag to protect load chain.
6. 6. Check direction of chain eyes. All welding points should be same direction. Hoist cannot be operated prop-
erly unless all welding chain eyes are in same line.
• Position hoist in vertical position to load. Before moving trolley, make sure path of hook is free from any
obstacle.
• Lower hook near master link to hoist load and make nal adjustments to secure a 90º vertical lift operation
without any lateral deviation. Improper life angle may cause swinging of load.
• Attach hook to load link and make sure there are no people in working area. Check that no loose items can
fall from load.
• Begin by hoisting load two inches and stop. Check brakes are fully operational and load doesn’t lower while
stopped. Also check load is balanced and secured. Load may have changed shape or center of gravity when
suspended.
• To reach a desired position, movements must be smooth and continuous. Repeatedly pressing buttons may
heat up motor and damage equipment.
• Avoid sudden directions changes. These movements may damage equipment, prematurely wear down
brakes and cause accidents.
7. Avoid any obstacle when hoisting or traveling load.
8. Start movement of trolley and check there is no swinging of load and no obstacles in path. Stop movement
and make necessary adjustments if one of these conditions is present.
9. Once desired position is reached, slowly stop trolley. Position load completely vertical to desired spot
where load will be lowered.
10. Gradually lower load until it is secured on resting surface. Avoid hitting surface at high speed. If necessary,
stop movement before reaching surface and gradually lower to land load.
If hoist model has double dual/speed capabilities, always start with slower speed to avoid sud-
den accelerations. Decelerate before completing a stop.
WARNING:
NEVER leave load suspended without attention of the hoist operator!
