ABSTRACT:
A bridge crane includes at least one main girder (1), a trolley moving on the main girder or at least one hoist gear fixed to the main girder, end carriages (4) arranged at the ends of the main girder to support the main girder, wheels arranged to the end carriages intended to move along substantially parallel rails (7) substantially parallel to the end carriages and on the other hand substantially transverse in relation to the main girder and thus to support the entire crane on the rails, while slides (10 to 17) have been arranged between one end carriage (4) and the corresponding end (9) of the main girder (1) allowing a longitudinal movement of the end carriage (4) in relation to the main girder (1) and a rotation of the end carriage and main girder in relation to each other.
