Abstract: A livestock loading device having a motorized conveyor belt, travelling on a variable height platform. The device is installed inside a livestock finishing building, with one end of the platform constrained to travel in a vertical plane within the doorway of the building. The opposite end of the platform is constrained within a track mounted on the floor of the building. The platform has vertical sidewalls, and horizontal side walkways. A pivoting attachment connects the platform to a wheeled frame, and a safety switch prevents over extension of the lift mechanism while accidental lowering of the platform is prevented by a safety switch.
