Top running bridge cranes are designed for facilities with low headroom. The system moves above the runway, allowing more space between the hook and the ground. A rail is installed on top of the runway beams for the wheels to ride on.
Generally a lot lighter than a top running system, underhung crane runways allows for more versatility. Underhung bridge cranes are typically used for lighter applications; under 20 tons. These systems can be mounted from the ceiling or interlocked together. Because the bridge runs underneath the runway rail, multiple systems can be run side-by-side without interfering with one another.
Push/pull or hand chain bridge cranes are the most cost-effective solution of the top running bridge crane options. This bridge crane style is limited to a 5-ton capacity due to the manpower it would take to lift and/or move a load of that weight.
