Hook is a commonly used lifting tool during lifting. As we all know, hooks are also divided into two types: single hook and double hook. Single hooks are often used together with sling ropes, and sometimes they are also combined with hook racks. Double hooks are only used on cranes. After understanding these categories and performance, do you understand what requirements do hooks have for making and using? Let me introduce it to you below.

The hook is forged with a whole piece of key material and needs to be annealed. The hardness is required to reach 95-135 (HB). The surface of the hook should be smooth and there should be no defects such as peeling, marking, acute angles, cracks, etc. The well is not allowed to repair the damaged hook to avoid brittle breakage and accidents. When lifting, the sling should be hung to the bottom of the hook; if the hook is directly hooked in the suspension ring of the component, the hook should not be hard or twisted. There are single hooks and double hooks. Single hooks are generally used for lifting work, among which the main size and lifting weight of the ring hook are. If the hook has permanent deformation and cracks, it should be scrapped. When the wear reaches 10%, it should be downgraded or replaced.
