The hook is an important force-bearing component of the electric hoist. During the process of lifting heavy loads, it bears the full load. Once the hook is broken, it will cause the spreader and weight to fall, and serious personal injury may occur. In order to improve the safety factor of electric hoist hooks, precautions should be taken.
Hook fracture usually occurs in the case of long-term friction and overload, cracks, deformation, and finally fracture. Therefore, it is strictly forbidden to lift heavy objects exceeding the rated load during use. Periodic inspection of the hook for poison and dangerous sections is required, and the hook needs to be annealed at regular intervals. When a crack occurs on the hook, scrap it in accordance with the provisions of GB10051-88. It is strictly forbidden to repair the hook before re-use, because there are serious safety risks.
