Single hook is simple to manufacture and easy to use, but the force is not good, most of them are used in the workplace with a lifting weight of less than 80 tons; Double hooks with symmetrical force are often used for large lifting weight. Laminated hook is riveted by several pieces of steel plate cut and formed, the entire hook will not be damaged when the individual plate cracks, large weight, mostly used in large weight or lifting steel bucket crane. The hook is often impacted during operation and must be made of carbon steel with good toughness.
Hook classification is very wide, generally including: shackle, ring, ring, pear ring, long ring, combination ring, S hook, nose hook, American hook Angle hook, eye slip hook, with insurance card ring screw, chain shackle features, suitable for factories, mines, petroleum, chemical industry and ship terminals.
