Lifting hook used for crane

Abstract

The invention discloses a lifting hook used for a crane. The lifting hook comprises a connector, stand columns, an end cover, at least one lifting hook body and an outer cover. The connector is installed at the bottom end of a lifting arm of the crane. The set of stand columns are symmetrically arranged on the other end face, opposite to the lifting arm, of the connector. The end cover is installed among the set of stand columns through bolts. The at least one lifting hook body is installed at the bottom end of the end cover in a hinged manner. Each lifting hook body is formed by hinging a hinge and a lifting lug. The outer cover is arranged on the at least one lifting hook body in a sleeving manner through the end cover. The hinges of the at least one lifting hook body are limited on the inner side end face of the outer cover, and the lifting lugs rotate in the horizontal plane relative to the hinges. The lifting hook is simple in structure, notches are additionally formed in a dustproof cover and used for completing containing of the lifting hook bodies, the phenomenon that because the lifting hook bodies are exposed, potential safety hazards exist is reduced, and the lifting hook is easy to operate, convenient and practical; and by arranging the at least one lifting hook body, stability of lifting is easily improved, and the lifting hook is safe to use.

Description

technical field

[0001] The invention relates to the technical field of hoisting, in particular to a hook for a crane. Background technique

[0002] Cranes are widely used in industrial production, construction, freight terminals, warehousing and other industries, mainly for hoisting various goods. In addition to the power unit and the steel rope for hoisting, the crane also has a hook. Most of the existing hook products are a single hook body, the lifting stability is poor, and the lifted object is prone to tilt or fall, and when the hook is idle, the hook is directly exposed, and it is easy to adhere to dust. And there is certain potential safety hazard in the lug of exposed suspension hook. Therefore, this paper proposes a hook for panel cranes that is easy to store and has high safety.

[0003] Therefore, in order to solve the above-mentioned existing problems, the present invention provides a new technical solution. Contents of the invention
