Abstract
The disclosed jack assembly is used to raise the frame of a railroad car to a sufficient height above a wheeled truck assembly coupled to the railroad car in order to perform maintenance or remove the truck assembly. The jack assembly comprises an air-operated bellows which raises and lowers a plate that engages the railroad car for the raising and lowering action. Telescoping posts and other support members aid in stabilizing the jack assembly during use in order to prevent failure of the bellows due to buckling under the weight of the railroad car. The jack assembly is readily mobile between locations, and can be operated by a single user.
