Abstract
An apparatus for lifting and moving an axle of a rail vehicle includes a frame, a pair of rollers rotatably mounted to the frame to movably support the frame on a railroad track rail, and a pair of wedges mounted to the frame having mutually opposed ramped faces. The pair of wedges adjustable along the frame between a first position in which the ramped faces bracket, but do not contact, a rail vehicle wheel that rests on the track rail, and a second position in which the ramped faces engage the circumference of the wheel to support the wheel at a height above the railroad track rail. The apparatus further includes at least one jacking device for urging the wedges toward one another from the first position to the second position.
