What kind of crane includes a hoist trolley that travels along a horizontal beam on overhead runways?

The overhead crane specifically refers to a system that features a hoist trolley moving along a horizontal beam mounted on overhead runways. This design allows for lifting loads and moving them horizontally across a large area, typically found in warehouses and manufacturing facilities. The main advantage of overhead cranes is their ability to maximize floor space and improve operational efficiency by utilizing vertical space for lifting, while the trolley can traverse the beam to position loads precisely as needed.

In contrast, bridge cranes are a subset of overhead cranes that include a bridge spanning the work area, while gantry cranes have a similar structure but are supported by legs that move on the ground. Jib cranes, on the other hand, feature a cantilevered arm and are usually stationary, which limits the horizontal movement capability compared to overhead systems. The design and operation of overhead cranes make them essential in various industrial applications where heavy lifting and precise load positioning are required.
