US 2017/0282941 A1 · RAIL CAR LIFTING DEVICE

Abstract

A lifting device for lifting a rail car includes a frame with a load plate movably disposed thereon and a back plate movably disposed on the frame and coupled to the load plate. The lifting device further includes a first actuator disposed on the frame and operatively coupled to the back plate and at least one second actuator operatively coupled to the load plate such that the first actuator and the at least one second actuator produce forces in first and second directions. Further still, the first actuator and the at least one second actuator move the load plate of the lifting device in a substantially vertical direction.

A method of lifting a rail car comprising:

arranging a lifting device across a rail way such that a rail car is above the lifting device;
wherein the lifting device includes a frame;
and
wherein a load plate is movably disposed on the frame and a back plate is movably disposed on the frame and coupled to the load plate;
raising the rail car by moving the load plate vertically, further comprising:
activating a first actuator disposed on the frame and operatively coupled to the back plate, the first actuator producing a force in a first direction;
and
activating at least one second actuator operatively coupled to the load plate, the at least one second actuator producing a force in a second direction transverse to the first direction;
wherein the first actuator and the at least one second actuator together operate to move the load plate vertically.
