Abstract

The application relates to the technical field of building construction and discloses hoisting equipment for building construction, which comprises a first supporting plate, a second supporting plate, a supporting rod, a guide rail, a sliding block, a bearing box, a steel wire rope and a winding and unwinding assembly. In the use process, the winding and unwinding assembly is controlled to work, so that the wire rope can finish winding or unwinding actions. And then drive the carrying case to move, thereby accomplishing the handling work. The guide rails and the sliding blocks positioned at the two sides of the bearing box can play a role of guiding and supporting in the moving process of the bearing box. Therefore, the bearing box can only move along the height direction of the supporting rod, so that the phenomenon of shaking and swinging of the bearing box under the action of external force is avoided, and the stability of the bearing box during movement is improved. Because the wire ropes are positioned at the two sides of the first supporting plate along the width direction of the first supporting plate, the two sides of the bearing box can be uniformly stressed when the bearing box is pulled to move. The horizontal load born by the guide rail and the sliding block is reduced, and the service lives of the guide rail and the sliding block are prolonged.
