A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places. The device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in the transport industry for the loading and unloading of freight, in the construction industry for the movement of materials, and in the manufacturing industry for the assembling of heavy equipment.

Overview/Description
Cranes have capacity limitations unlike most other pieces of construction equipment. If a bulldozer attempts to push too much dirt, usually nothing bad happens. The equipment merely bogs down. Nothing breaks, and no one gets hurt. To recover, the operator merely backs up a bit, raises the blade and pushes on. If a crane exceeds its capacity limitations, there is usually a significant accident.
More than most pieces of equipment, gravity is working to collapse the equipment or cause the crane’s load to fall to the ground. If the crane does not overturn, a structural failure could occur, with similar damage and results. Contrary to some conceptions, the design safety factor applied to cranes is quite small. Exceeding the structural or tipping capacity of a crane by even a modest amount can cause a serious accident.
There are three basic types of crane accidents:
- Structural failure
- Tip-over
- Collision
- Operations
- Assembly/disassembly
- Rigging
- Maintenance
- Weather
