What is the working principle of crane?

The working principle of the crane is as follows:

The crane is composed of driving device, working mechanism, fetching device, control system and metal structure. By manipulating the control system, the driving device converts the input electric energy into mechanical energy, and transmits the acting force and moving speed to the fetching device. The material taking device connects the transported materials with the crane, and the working mechanism moves alone or in combination to complete the material handling task. The movable metal structure connects all the components into a whole, and carries the crane's own weight and lifting load.
