Background

In the process of machining a steel structure, the steel structure member is often required to be hoisted. In the hoisting process of the steel structural member, a lifting hook for hooking the steel structural member is an essential part for hoisting. The lifting hooks used in steel structure hoisting operation are generally divided into forged hooks and sheet hooks. The two hooks have obvious advantages in the hoisting process, and the cross section area of the hooks is large, so that the bearing capacity is large. However, in the process of hoisting the steel structural member, the two types of hooks have a defect that the widths of the two types of hooks are narrow, so that the contact surface between the hook and the steel structural member in the process of hoisting the steel structural member is small, the steel structural member is easy to deform in the hoisting process, and especially the deformation is more obvious when some steel structural members with small out-of-plane rigidity are hoisted, for example, when steel plates, U ribs, H-shaped steel and the like are hoisted, the deformation can affect the quality of the steel structural member.
