It is mainly used for moving objects to other places and lifting heavy things. The equipment uses one or more simple machines to make mechanical strength, and therefore, it can moves loads beyond the capability of a human.

Cranes are generally used in the workshop, warehouse, garage, workstation, transport industry, construction industry and assembly factory etc. And there are different types of cranes, such as overhead gantry crane, overhead bridge crane, jib crane, and monorail crane etc. Different cranes have different technical parameters, features, advantages, and applications.
