Novel special lifting hook for crane

Abstract

The invention discloses a novel special lifting hook for a crane. The novel special lifting hook comprises a lifting box and a lifting hook body, a cavity is formed in the lifting box, a wire hole communicated with the cavity is formed at the upper end of the lifting box, and a through hole communicated with the cavity is formed at the lower end of the lifting box. According to the novel special lifting hook for the crane, a take-up wheel is arranged in the cavity of the lifting box and connected with the output end of a motor fixed to the side wall of the lifting box through a rotating shaft,and due to the design, after an operator of the crane descends the lifting hook to the position above goods at a time, a carrying person below controls a motor to be started through an adjusting switch; and secondary adjustment of the height of the lifting hook is achieved, the proper height is formed between goods and the lifting hook, and the carrying person can conveniently fix the goods to the lifting hook.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a special hook for a new type of crane. Background technique [0002] Crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. The lifting hook is a component of a crane, which is often used to lift heavy objects. [0003] At present, in the existing crane hook, the hook can be raised and lowered by the wire rope. However, when the operator of the crane controls the lowering of the hook, he can only roughly lower the hook to the top of the goods, and at this time, the goods are not connected to the goods. Most of the distances between the hooks are too high or too low. This inappropriate height makes it inconvenient for the handling personnel to fix the goods on the hooks, so it is necessary to improve the design. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to address th...

Problems solved by technology

[0003] At present, the hook of the existing crane is driven by the steel cable to rise and fall. However, when the operator of the crane controls the descent of the hook, he can only roughly lower the hook to the top of the cargo. The distance between the hooks is mostly too high or too low. This inappropriate height is inconvenient for the handling personnel to fix the goods on the hooks, so it is necessary to improve the design
