How to repair the hook
Hook Al though it is only a component of crane equipment, it also needs to be inspected frequently. So how should multiple hooks be inspected?
(1) Use kerosene to clean the body of the hook frequently, and use a magnifying glass to conduct a comprehensive inspection. If cracks are found, they must be replaced immediately.
(2) Check parts such as pull plates, cross beams, etc. When the pull plate holes are severely worn, you need to use welding rods to repair and reboot: If you replace a new part, you must ensure that the mechanical quality of the material meets the original work requirements.
(3) The hook that has been used for a certain period of time will harden the surface of the hook due to the action of the wire rope. Therefore, the hook needs to be annealed once a year. The annealing temperature of the forged hook of No. 20 steel is 500-600℃, and it can be slowly cooled after insulation to ensure that its mechanical properties remain unchanged.
The hook group must undergo a comprehensive inspection every year, and the hook body should be inspected separately every quarter.
