摘要

Trolley, preferably designed as a trolley running on a bottom flange on a gantry or container crane, comprises an upper part (4) and a lower part (5) which are joined together. A chassis support (1) arranged over each rail of the trolley traveling way has two compression-tension girders (2) and two chassis girders (3) leading toward the lower part and arranged so that the chassis support can act as a bending girder. The lower part is a chassis (6) consisting of a truss (7) connected by chassis girders (10) to a lifting gear frame (8).
