Abstract

A trolley having an operating position suspended from an overhead load carrying beam of a crane. The trolley has upward extending arms having wheels mounted at their upper ends for supporting the trolley on rails affixed to the beam. Drive motors are mounted on the arms adjacent the wheels for moving the trolley along the beam. The arms are pivotally connected at their lower ends to a trolley platform which carries a hoist.
The arms may be pivoted outward and downward during factory assembly of the trolley to facilitate mounting of the wheels and drive motors on the arms. During shipment of the trolley, the arms may be pivoted inwardly of the platform to minimize the trolley width. The arms may also be pivoted to assist in mounting the trolley on the beam.
