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.
