ABSTRACT:
A railroad coupling knuckle hoist and method is provided which facilitates the movement, lifting and placement of a knuckle in an operative position in the coupling head of a drawbar in a safe and efficient manner by using a portable, lightweight knuckle hoist which is temporarily attached to the upper surface of a drawbar and which serves to mechanically move, lift, and maintain a knuckle in position to be received in the coupling head. In accordance with one example, the railroad coupling knuckle hoist includes a base which is adapted to be placed on the upper surface of the horn of a drawbar adjacent the buffing surface, a securing chain for temporarily securing the base to the drawbar, a winch attached to the base and including a crank handle for manually operating the winch, a boom extending upwardly from the base and including a guide element at the free end thereof for guiding a lifting cable from the winch in a position to lift a knuckle to a location adjacent a knuckle receiving recess in the coupling head of the drawbar, and a lifting assembly attached to the lifting cable and adapted to be temporarily clamped onto the knuckle while the knuckle is moved, lifted, and placed in the coupling head and detached from the knuckle once it is held in position within the coupling head of the drawbar by a temporary holding pin. A ramp is used for facilitating movement of a knuckle over a railroad train track.
