Abstract
An articulating suspension for the bridge of an overhead bridge crane allows the bridge to be skewed from perpendicular to the parallel runs that support the bridge. The runs are allowed to pivot toward each other on pivot axes above and parallel with each run. End trucks that support end regions of the bridge from each run are interconnected with the bridge via suspension hangers. These are suspended on end truck pivots that are parallel with the runs and include thrust bearings that allow the bridge to skew. The bridge is suspended from the hangers on a pivot axis above and parallel with the bridge. The arrangement allows the necessary freedom of movements for skewing the bridge without making the crane wobbly or unstable. The arrangement of pivot pins and thrust bearings also is rugged and durable and requires little maintenance.
