An overhead crane, also known as a bridge crane, is a crane used in industrial plants and warehouses for the transportation and handling of heavy loads. In a bridge crane, the rails of the crane bridge are mounted on the ceiling or wall of a hall, which enables efficient use of the available space.

The crane bridge of the overhead crane carries a trolley that supports the hoist drive with rope drum, the hoisting gear. This trolley can move along the longitudinal crossbeam of the bridge to move loads horizontally. The actual lifting operation is carried out by the hoist, which raises and lowers the loads.

There are two main types of bridge cranes: single girder bridge cranes and double girder bridge cranes. A single girder overhead crane has only one girder supporting the crane bridge, while a double girder overhead crane has two girders supporting the crane bridge. The choice between these two types depends on various factors, including the load capacity and the required span.

Overhead cranes are used in a variety of industries, including manufacturing, warehousing, shipbuilding, automotive and logistics. They are particularly useful for transporting heavy loads over long distances and offer high efficiency and flexibility in material handling.

Due to their robust design and versatility, overhead cranes are an essential tool for companies that need to move heavy loads safely and efficiently.
