Main purpose:
Underrunning end carriages are designed for mounting the bridge of an underrunning crane and ensuring its travel along the crane runway on the lower flange of an I-beam. The end carriages take the loads from the bridge structure, the trolley and the load, and transfer them via the travel wheels to the runway girder.

One of the underrunning end carriages is equipped with a floating unit in the form of a roller support. This design solution ensures the static determinacy of the structure and helps to reduce internal stresses in the crane steel structure.
