Workshop Roof Top Running Bridge Crane for Safe Industrial Use

A top running bridge crane is one of the most widely used types of overhead cranes due to its versatility and strong load-handling capability. It is commonly applied across a wide range of industries, including manufacturing, warehouses, workshops, and heavy fabrication facilities. These cranes can be designed with lifting capacities of up to 32 tons and spans reaching 35 meters, while most standard applications typically fall within the 5–10 ton capacity range. For lighter capacities, I-beam girders are often used, whereas larger spans and higher capacities generally require robust box girder structures for improved strength and stability.

In a top running configuration, the hoist and trolley are underhung, traveling along the bottom flange of the bridge girder. While this design ensures smooth and reliable lifting, it does require more vertical space, making it less suitable for buildings with strict headroom limitations.

Top running bridge cranes travel on end trucks mounted on rails fixed to the top of runway beams. These runways can be either building-supported or freestanding, depending on site conditions. Although highly efficient, hook coverage is limited to the runway area, as the trolley cannot move beyond it.
