How to perform maintenance on electric rotating hook group

Although the electric rotating hook set is only a small part on the crane, it also needs daily maintenance. So how should we check it? Let’s have a brief understanding with the hook set manufacturer!

(1) Frequently clean the body of the hook with kerosene, dry it and use a magnifying glass to conduct a comprehensive inspection. If cracks are found, they must be replaced immediately.

 (2) Check the tie plates, beams and other parts. When the tie plate holes are severely worn, it is necessary to use high-quality welding rods to repair the holes and re-boring them: If new parts are replaced, it must be ensured that the mechanical quality of the material meets the requirements of the original work.

(3) The surface of a hook that has been used for a certain period of time will harden due to the action of the wire rope. Therefore, the hook needs to be annealed once a year. For forged hooks made of No. 20 steel, the annealing temperature is 500 to 600°C. Only by slow cooling after heat preservation can the mechanical properties remain unchanged.

The hook set must be comprehensively inspected every year, and the hook body should be inspected individually every quarter to see if it is damaged.
