Forged Safety Hook with Latch, Heavy Duty Hooks for Truck Trailer Lifting

The hooks can be made of 20 high-quality carbon steel or forged with special materials such as DG20Mn and DG34CrMo. It is strictly prohibited to use cast hooks. The plate hook is generally made of A3 and C3 ordinary carbon steel or 16Mn low alloy steel. The longitudinal axis of the hook plate must be located in the rolling direction of the steel plate, and the hook plate is not allowed to be spliced. The hook piece of the plate hook shall be riveted with countersunk rivets, and the high stress bending part where the plate hook contacts the lifting point of the lifting object shall not be connected with rivets.

The hook is simple to manufacture and convenient to use, but its stress is not good, and it is mostly used in the working places where the lifting capacity is less than 80 tons; Double hooks with symmetrical force are often used for large lifting capacity. The laminated hook is riveted by several pieces of cut and formed steel plates. The whole hook will not be damaged in case of cracks in individual plates. It has good safety, but has a large deadweight. It is mostly used on cranes with large lifting capacity or for lifting molten steel drums. The hook is often impacted during operation and must be made of high-quality carbon steel with good toughness.
