Description

Cantilever crane capable of rotating 360 degrees Technical Field The application relates to the field of cantilever cranes, in particular to a cantilever crane capable of rotating 360 degrees. Background The cantilever crane is used as common lifting equipment and has the capability of rapidly and accurately carrying goods. The cantilever crane can replace manual lifting and conveying efficiency, and can make up for the defects of large-scale lifting equipment in flexibility and cost. Therefore, cantilever crane is a preferred solution for industrial material handling, which is both practical and economical. With the development of industrial automation, the requirements on the flexibility and the efficiency of the hoisting equipment are higher and higher. However, conventional cantilever cranes typically employ a fixed or limited angle rotation design. On the one hand, the cantilever crane of the fixed cantilever crane is fixed at a certain position and cannot rotate, on the other hand, the cantilever crane of the limited-angle rotating cantilever crane can rotate within a certain angle range, usually 180 degrees or 270 degrees, and the rotation range is limited and cannot realize 360-degree omnibearing rotation. The traditional cantilever crane cannot realize 360-degree omnibearing rotation, so that the requirements of certain special occasions cannot be met, and the operation flexibility is insufficient and the working efficiency is low. Disclosure of utility model In order to solve the problems of insufficient operation flexibility and low working efficiency caused by the fact that the traditional cantilever crane cannot realize 360-degree omnibearing rotation, the application provides the cantilever crane capable of rotating by 360 degrees.
