Abstract

The invention discloses a hoisting device of a crane. The hoisting device comprises a main jib of the crane and a trolley arranged on the main jib, wherein the trolley is connected with a workbench through a telescopic arm, and a rotary platform is arranged below the workbench and is driven through a hydraulic motor; the joints of first and second swinging arms are arranged below the rotary platform; each section of swinging arm is driven through a hydraulic motor; a mechanical arm is arranged on the lowest swinging arm. The hoisting device is capable of completing hoisting operation at occasions with narrow space and hazardousness and under condition that a work piece self has dangerous situation; as no auxiliary operator is needed, the labor cost is saved.

Description

technical field [0001] The invention relates to a crane, in particular to a crane lifting device, and belongs to the technical field of cranes. Background technique [0002] As we all know, when a crane is performing a lifting operation, it generally requires the cooperation of two people to complete the lifting task, that is: the driver of the vehicle and the operator of the lifting hook, so there is a defect of high labor costs. Due to the narrow space and safety reasons, it is also impossible to use the method of manual hooking to realize the lifting operation, so this will bring a lot of inconvenience to the production, and sometimes even the production operation cannot be completed. Contents of the invention [0003] The purpose of the present invention is to solve the problems that the existing cranes have high labor costs during the operation process, and cannot complete the lifting operation in some narrow spaces, dangerous places, and dangerous c...
