Electric Chain Hoist is a new style and small lifting equipment, is an ideal tool to lift heavy objects, load and unload, maintain equipment. Also called Electric hoist, Electric lifting hoist, Monorail hoist, Powered hoist, Powered chain hoist, Hoist.

It uses squirrel cage motor for driving.

It is widely used in factories, mines, agriculture, electric power, construction building site, dock and warehouse.

Detailed Description

1. Shell

They are made of Light aluminum alloy through compression casting formation.

Advantages: Solid and light but hard

Fast release heat

Continuous use

Enclosed structure

Can be used in the terrible work environment with a high heat dissipation rate and all tightness design. such us chemical plants, electroplating factories, and other places.

2. Support frame

The loading support frame consists of two steel plates, which is extremely sturdy.

3. Side magnetic braking device

It is the latest design which is featured for generating magnetic force.

This masterly structure ensure the hoist absolutely safety when the power off. And ensures it is safe when overload.

Also it combines to the motor braking as the double brake system to strengthen security and durability.

4. Inverse phase sequence protecting device

It is the special electrical installation which controls the circuit not to work in case of wiring error in the power supply.

Advantages: When power-supply wiring mistake, the control circuit is unable to move.

5. Limit switch
The limit switch device is installed where the weight is lifted on and off to make the motor to stop automatically so as to prohibit the chains from exceeding for safety.

6. Transformer: 24V/36V transformer device
It is used to prohibit the emergencies from occuring in case of the leakage in the switch.

It guarantees safe while use in rain.

7. Gear

The gear is made of alloy steel and through the heat treatment.

8. Hooks

They are made by hot forging and heat treatment with perfect strength that is hard to break, the operation safety of the lower hook is ensured by its 360 degree rotation and safety tongue piece (latch).

9. Chain

It is made of FEC80 ultra strong heat treatment aluminum alloy steel.

Advantages: It is safely approximately when used in the rain water, the sea water, under the chemical and other bad conditions.

10. Chain bag/container
It is light, handsome and durable.

11. Push button

Waterproof push botton is applied, it is light and durable, come with the E-stops.

12. Classification: M4, M5 (ISO); 1Am, 2m (FEM); H4 (ASME)

Insulation grade: F

Suspension varieties: Hook, manual trolley, motorized trolley

Operating temperature: -20 to 40 ℃ (-4 to 104 °F)

Operating humidity: 85% RH or less.

13. Protection class (hoist and push button): IP54 (standard)

Standard one is for indoor use, It is suitable for outdoor operation but need to avoid directrain.

protection class should be improved (IP55) if for outdoor use, otherwise, Motor may be burned.

14. Noise (single/ dual speed): 81dB.

15. Bumpers

Optional, there are two kinds: plastic and silica gel

16. Hermetical treatment

Optional, we use non hole seal (normal one has hole) special for IP55, the water could not get in.

17. Outside overload protector

Optional

18. Spring

Rotation direction: right

Heat treatment: HRC44-50

Surface oxidation treatment

19. Adjustment value of brake

It is adjusted according to glide quantity measuring condition when rated loading is made on test bed, after using some time the glide quantity will increase, it could be adjusted by special tools for brake screw. We can supply a brake tools before delivery if needed.

Trolley brake could not be adjusted (pad thickness is 4mm for all capacity trolley)

20. Gear box oil adding

ISO46 refrigerating machine oil, 0.7L-3L according to different capacity. If oil leaking is in electric parts, need to clean firstly.

21. Others

For Dual voltage, only single speed is available.

For Single voltage, dual speed is available.

(Reason: motor is too small and impossible for wiring 4 lines if dual voltage, dual speed)

Tips after receiving electric chain hoist:

① The bottom hook does not swivel

Molding powder is a little thick and tighten, pls swivel for some times and could be rotated, since there is no grease in the bearing (not greased prior to shipping).

② Squeaking on motion sometimes

Side rollers do not have bearing and are not lubed, It would be nice for to spray with a dry lithium lube or something that will not drip, and it will not squeak.

③ The hoist breaks do not fully open and they are not stuck

Find a copper stick, remove the plastic cover of motor, beat motor shaft for 2-3 times.

Problem: usage time is long.

④ Operated the hoist with out any load and it worked correctly for up and down motion, But it tested with load and the hoist could not hold the load or pass the load test.
Move the limit switch up and down for several times, and operate the hoist again.

Problem: limit switch is blocked.
