The PTC-2 is a self-propelled compact tie changer for standard crossties and switch ties. The controls are operated by means of manually activated hydraulic valves with the operator standing next to the machine. The machine has adjustable rail clamps, tilting tie clamp workhead, horizontal extraction boom and manual parking brake. The tilting workhead rotates approximately forty degrees, designed to permit the tie to be tilted during insertion or extraction to clear adjacent track. The PTC-2 also has two pair of raise/lower hydraulic cylinders mounted directly above each wheel. Side set-off wheels are provided which, when used with the raise/lower system, permits the machine to be off-tracked by the operator.
