Hook usage requirements
Hooks are commonly used lifting tools during lifting. As we all know, hooks are divided into single hooks and double hooks. Single hooks are often used together with slings, and sometimes in combination with hook frames; double hooks are only used on cranes. After understanding these classifications and performances, etc., do you understand the requirements for the production and use of hooks?
Let me introduce to you:
(1) The hook should be forged from a whole piece of key material (usually No. 20 carbon cable steel) and needs to be annealed, with a hardness requirement of 95-135 (HB).
(2) The surface of the hook should be smooth and should not have defects such as peeling, nicks, sharp angles, cracks, etc. It is also not allowed to repair and repair damaged hooks to avoid brittle fracture accidents.
(3) When hoisting, the sling should be hung to the bottom of the hook; if the hook is directly hooked in the lifting ring of the component, the hook cannot be hard or twisted.
(4) Hooks are available in single hook and double hook types. Single hooks are generally used for lifting work, among which the main dimensions and lifting capacity of ring hooks are.
(5) If the hook has permanent deformation or cracks, it should be scrapped. When the wear reaches 10%, it should be downgraded or replaced.
