    Points of routine maintenance of explosion-proof chain hoist


Description: Explosion-proof chain hoist is a type of chain hoist with "explosion-proof" characteristics, which is safe and reliable, easy to maintain, high mechanical efficiency, low tension, light weight, easy to carry, beautiful appearance, small size, durable Features, suitable for lifting goods in factories, mines, etc., especially for open-air and power-free operation, it shows superiority.

Explosion-proof chain hoist is a type of flame-proof chain hoist, which has the characteristics of safety, reliability, easy maintenance, high mechanical efficiency, low tension, light weight, easy to carry, beautiful appearance, small size, and durability. It is suitable for lifting goods in factories, mines, etc., especially for open-air and non-power operation, it shows superiority.

The main points of explosion-proof chain hoist maintenance are as follows:

Explosion-proof chain hoist

1. After use, the hoist should be cleaned and coated with anti-rust grease, and stored in a dry place to prevent the explosion-proof hoist from being rusted and corroded.

2. Maintenance and overhaul should be performed by those who are more familiar with chain hoist mechanisms. Use kerosene to clean the chain hoist components. Lubricate the gears and bearings with grease to prevent those who do not understand the principle of the machine from disassembling.

3. After the explosion-proof chain hoist is cleaned and repaired, no-load test should be performed to confirm that it is working normally and the brake can be delivered before use.

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

5. The rollers of the left and right bearings of the lifting sprocket of the explosion-proof chain hoist can be adhered to the bearing inner ring that has been press-fitted on the journal of the lifting sprocket with butter, and then installed in the bearing outer ring of the wall plate.

6. When the explosion-proof chain hoist is installed with the brake device, pay attention to the good meshing between the ratchet tooth groove and the pawl claw. The spring should control the pawl flexibly and reliably. After installing the hand sprocket, rotate the hand chain The ratchet wheel and the friction plate are pressed against the brake seat, and the bracelet wheel is rotated counterclockwise, and a gap should be left between the ratchet wheel and the friction plate.

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

8. In the process of using explosion-proof chain hoists , 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 down due to brake failure.
