Description

A lifting device for construction sites

Technical Field

The utility model relates to the technical field of construction engineering, in particular to a lifting device used in a construction site.

Background Art

Construction refers to production activities during the implementation phase of engineering construction. In construction sites, building materials need to be transported from low ends to high places. At the same time, lifting devices can reduce the workload of workers and improve convenience during construction.

In the lifting device, a motor is used to drive the roller to rotate, and the roller drives the pull rope to retract, and the hook installed at the lower end of the pull rope can limit the installation of the items to be lifted. After the connecting rope is retracted, the lifting device can be controlled to move the items to floors of different heights, thereby improving the convenience of material handling. At the same time, the hook is fixed by traction with the connecting rope. When the connecting rope is lowered too long, the hook drives the material to move upward. The lifting equipment is placed outdoors, and there is natural wind outdoors. When the natural wind is too strong, the lifted items will sway everywhere under the action of wind, and the swaying objects will touch the lifting frame or the building, thereby affecting the safety of the building during lifting. For this reason, we have proposed a lifting device for construction sites.
