Maintenance method of chain block

1. After use, the hoist shall be cleaned and coated with anti rust grease, and stored in a dry place to prevent the chain hoist from moisture, rust and corrosion.

 

2. Maintenance and overhaul should be carried out by those who are familiar with the hoist mechanism. Clean the hoist parts with kerosene and lubricate the gears and bearings with butter to prevent those who do not understand the performance principle of the machine from disassembling and assembling at will.

 

3. After cleaning and maintenance, the hoist shall be subject to no-load test to confirm that it works normally and the braking is reliable before it can be delivered for use.

4. The friction surface of the brake must be kept clean. The brake part shall be checked frequently to prevent brake failure and heavy objects from falling.

 

5. The rollers of the left and right bearings of the lifting sprocket of the chain block can be adhered to the bearing inner ring pressed on the Journal of the lifting sprocket with grease, and then installed into the bearing outer ring of the wallboard.

 

6. When installing the brake device part of the chain block, pay attention to the good engagement between the ratchet gear slot and the pawl part, and the control of the spring on the pawl should be flexible and reliable. After installing the chain wheel, rotate the chain wheel clockwise, press the ratchet and friction plate on the brake seat, rotate the chain wheel counterclockwise, and there should be a gap between the ratchet and friction plate.

 

7. For the convenience of maintenance and disassembly, one section of the bracelet is an open chain (welding is not allowed).

 

8. In the process of refueling and using chain block, the friction surface of the braking device must be kept clean, and the braking performance must be checked frequently to prevent heavy objects from falling due to braking failure.

 

BTW: Any requirement regarding chain hoist, mini electric hoist or Any other lifting equipment.
