Crampon for building crane

Abstract

The invention discloses a crampon for a building crane, and relates to the technical field of crane accessories. The crampon comprises a fixing rod. The fixing rod is inserted in the upper portion ofa crampon body in a penetrating mode and located below a connecting mechanism. The upper end of the crampon body is mounted at the lower end of the connecting mechanism. The connecting mechanism comprises a mounting block, connecting blocks, a bearing and a rotating seat. A limiting mechanism is mounted at an opening of the crampon body and comprises a connecting piece, a spring, a baffle, a stopping block and a pin shaft. Reinforcement bars are mounted on the lower portion of the crampon body. According to the crampon, by arranging the connecting piece, the spring, the baffle, the stopping block, the pin shaft, the mounting block, the connecting blocks, the bearing, the rotating seat and the reinforcement bars, the problems that when the crampon is used, a baffle part is prone to rusting,and the crampon is poor in safety and unstable in lifting work when used are solved.

Description

technical field [0001] The invention relates to the technical field of crane accessories, in particular to a lifting hook used for construction cranes. Background technique [0002] One is a shackle or hook with a chain or rope attached, and another thick hook, usually with a handle, especially a hook used to carry goods or hang meat. The most common type of spreader in lifting machinery , the hook is often suspended on the wire rope of the lifting mechanism by means of pulley blocks and other components. The hook is divided into single hook and double hook according to the shape; it is divided into forged hook and laminated hook according to the manufacturing method. The single hook is simple to manufacture and easy to use. It is convenient, but the force condition is not good, and it is mostly used in workplaces with a lifting capacity of less than 80 tons; when the lifting capacity is large, double hooks with symmetrical force are often used. The laminated hook is riveted...
