Machine Description

Knox Kershaw’s KTR 450 Tie Replacer is an operator-friendly low-maintenance machine capable of removing and inserting timber and concrete ties. The 88”-stroke workhead generates extraction forces exceeding 23,000 lbs. A wide offset cab gives the operator full view of the workhead and ties.

  • Mainframe

    All-welded construction grade tubular steel with high strength reinforcing plates. The open bridge design places the workhead directly in front of the operator for maximum visibility.

  • Cab

    Fully enclosed cab includes ergonomic seat with joystick workhead controls. Air conditioner/heater and pressurizer, travel and work lights, horn, window wipers, and fire extinguisher are all standard equipment. Cab door opens to platform accessible from either side of machine.

  • Power Unit:

    Cummins Model QSB4.5, 110 hp, Tier 3, 24 Volt. Engine. Electronic engine warnings and protection shutdowns. Hydraulic system pressure compensated pump (direct coupled to engine) provides power for propel and workhead functions. A double-gear pump (coupled to pressure compensated pump) continuously cools/polishes the hydraulic oil and powers the hydraulically driven A/C.
    Fuel: 88 gal. (333 L); Hydraulic Tank: 64 gal (242 L)

  • Workhead

    High strength composite bushings and lubricant-impregnated wear pads minimize grease requirements while extending service life. Carbide plated/coated tie grippers resist wear.

  • Propel System

    Both 3” diameter alloy steel axles are chain-driven by hydraulic motors in a series/parallel circuit. The front axle is a “rocking” type to conform to track irregularities.

  • Standard Features

    High-lift fixed turntable, center lifting point, pressure and return filters, filter service indicators, stainless steel fluid tubing, manual valvebank overrides, anti-skid grip strut decking, positive door latch, emergency pump.
