What is the reason why the hand chain hoist cannot be pulled in the reverse direction?

When the hand chain hoist cannot be pulled in the reverse direction, the possible reasons and solutions are as follows:

1 Check for external resistance. Make sure there are no tripping objects or other obstructions impeding the movement of the Chain Hoist

.

2 Clean and lubricate. Check the pulleys, gears and chains of the hand chain hoist for dust or debris, clean them off and lubricate them with the appropriate lubricant.

3 Check the chain tension. Verify that the chain is installed correctly and maintains proper tension. If the chain is loose, it can be adjusted using a manual chain tensioner.

Check the brake of the hand chain hoist. Verify that the brake is fully released, if not, try to release the brake and try to pull the chain hoist again.

4 Check that the lifting chain is stuck. If the hand chain is stuck between the cover and the sprocket, we will not be able to pull the hand chain. twenty three

5 Check whether any foreign objects have fallen inside the chain hoist. This may cause chain jamming.

6 Check whether there is any problem with the hand pull sprocket. If there is a problem during the meshing process of the hand-operated sprocket and the hand-operated chain, we will not be able to pull the hand-operated chain at this time.

7 Check whether there is any problem with the transmission mechanism. If there is a problem with the transmission mechanism of the hand chain hoist, it will cause them to be unable to complete the normal rotation function. Therefore, when we pull the hand chain, the hand chain hoist will not be able to operate.

8 Check the braking system for malfunction. If you can only pull one side but cannot pull the other side, it may be that the braking system is faulty. You should check the braking system, such as whether the friction plate is broken or the ratchet and pawl. If the accessories are damaged, replace them in time. If they need to be cleaned, clean them.

If you still cannot solve the problem after trying the above methods, it is recommended to contact professional maintenance personnel for further inspection and repair.
