ABSTRACT:
A crane trolley is movable by means of rollers on the lower flange of a runway girder, the crane trolley having a hoist, the latter being inserted in one of the two sides plates of the crane trolley. The load chain of the host is guided by means of guide rollers. The chain is fastened with one end to the crane trolley and is driven by the load chain wheel of the hoist and carries the lower block with the load hook. The hoist is arranged off-set in the longitudinal direction of the crane trolley relative to the lower block and the load chain is guided over two additional guide rollers in S-shape between the load chain wheel of the hoist and the pulling chain portion of the lower block.
