As the crane lowers the beam to the railcar roof, the leveling spreader bar will adjust to the center of gravity during and after the lift with an individual radio controlled, hand-held unit the crane operator will be in possession of.
The motorized load-leveling spreader was designed to assist rail companies in removing various lengths and weights of roofs from their rail cars. There can be up to 10 lifting points on the roof. The 10,000 lb lifting capacity spreader beam is made of three assemblies: the long beams and the center assembly, making the unit easy to disassemble for storage purposes. It also includes casters so it can be maneuvered along the floor once it has completed its work.
