How the cantilever crane rotates

There are two types of cantilever spreaders used in common cantilever crane operations. One is a fixed cantilever spreader and the other is a rotating cantilever spreader. It is equipped with a reusable electric hoist.

　　The uprights of fixed cantilever spreaders are mostly frame structures. The fixed connection between the uprights and the beams cannot be rotated. The electric hoist can only move left and right along the beams and cannot rotate with the beams. The lifting operation is very inconvenient.

The beam of the rotating cantilever spreader can rotate around the column, so the sports car hanging on the beam can also rotate around the column. The installation area is large, and sometimes it has a serious impact on the workplace operation and equipment layout.

The beam of the rotating cantilever spreader is fixedly connected with the lower part of the column. The upper and lower ends of the column are respectively installed in the upper and lower bearing seats by rolling bearings. The column can rotate around its axis line. The beam and the sports car hanging on the beam can also rotate with the column. , During operation, the workpiece can be hoisted within a certain range, which greatly reduces the labor intensity of the handlers, and the hoisting operation is very convenient.

The rotating cantilever crane can be fixed on the wall or column, especially on the wall or column at the corner of the wall. Its installation does not need to occupy the ground of the workplace, which is not only conducive to the handling of workpieces and heavy objects, but also to the staff. Activities without affecting the layout of equipment in the workplace.
