ABSTRACT:
A tie exchanger assembly is mounted upon a truck and is used for removal and insertion of ties in a railroad roadbed. A boom is mounted to a rail clamp table which is vertically movable between an upper stored position and a lowered operable position. The boom is mounted to the center of the rail clamp support table and is rotatable 180.degree. about a vertical axis so that the boom may be used for manipulating ties on both sides of the vehicle. Rail clamps and rail engagement wheels are mounted to the underside of the rail clamp table. The boom is pivotable about a horizontal pivot axis. A tie clamp is mounted at a distal end of the boom. A self-aligning tie clamp may advantageously be used so as to clamp concrete ties or other ties with irregular or concave surfaces.
