What is overhead crane?

An overhead crane is a lifting device that is horizontally mounted above a workshop, warehouse or material yard to lift materials. It is also called bridge crane. Because its two ends are located on tall concrete columns or metal supports and its shape resembles a bridge, it is commonly called “bridge crane” or “overhead crane”.

The bridge of the overhead crane runs longitudinally along the tracks laid on the elevated platforms on both sides, and the lifting trolley runs horizontally along the tracks laid on the bridge, forming a short working range. The space under the bridge can be fully utilized to lift materials without being hindered by ground equipment.

Overhead cranes are the most widely used and largest type of lifting machinery and are widely used in indoor and outdoor warehouses, factories, docks and open storage yards.
