The RT240 Rough Terrain Container Handler (RTCH) is a 53,000 pound capacity, variable reach container handler that allows Army units to transload intermodal freight containers and other loads in a variety of mission scenarios. The RT240 is a key component of the Army’s supply distribution mission. This contract action seeks to procure 38 separate spare part components to support the Army’s RTCH fleet. The list of components included are listed below:

1 - 2. Axle Assembly, Vehicular part number MP-0029790 and NSN 2520-01-654-0360, and Axle Vehicular, Nondriving part number EP-0000266 and NSN 2520-01-656-8150 are the front and rear axles of the RTCH, providing travel and mobility to the machine.

3. The Mechanical Transmission part number EP-0001543 and NSN 2520-01-514- 0890 is a component of the RTCH powertrain. It takes the engine output and transfers it to the axles to propel the machine in either forward or reverse motion.

4 – 5. The Hydraulic Motor part number MP-0000201G with NSN 2540-01-520-7864, is the top handler slewing motor. Hydraulic Motor part number EP-0023636 with NSN 2540-01-520-7862, is the top handler spreader motor. These components provide precise control for the top handler for extension, retraction, and movement. The top handler is the main attachment for the RTCH, enabling the engagement of ISO containers.

6. The Parts Kit, Fork Lift part number EP-0020139 with NSN 3930-01-550-5631 is the fork lift attachment for the RTCH. This attachment has hydraulically actuated fork tines and a supporting structure, allowing the RTCH to engage loads such as pallets and flatracks.

7. The Material Hoisting Unit part number EP-0008993 with NSN 3950-01-542-2909 is the lifting and elevating structure of the RTCH. It is a hydraulically extendable, multi-section boom that connects the RTCH to the top handler.

8 – 10. The Hydraulic Pump part number EP-0011189 with NSN 4320-01-480-4880 is a hydraulic pump that directs hydraulic flow for the steering and top handler functions of the RTCH. The Hydraulic Pump part number EP-0003049 and NSN 4320-01-480-4889 serves the radiator fan and front axle cooling. The Hydraulic Pump part number EP- 0003050 and NSN 4320-01-480-4877 serves the boom and brake system.

11 – 17. The Flow Control Valves (see table below) include a variety of control valves that direct hydraulic flow to actuate several different functions in the RTCH.

Flow Control Valve EP-0002496 NSN 4820-01-480-4846 Radiator fan control Flow Control Valve EP-0002254 NSN 4820-01-480-4860 Boom servo Flow Control Valve EP-0002521 NSN 4820-01-480-4892 Steering control Flow Control Valve EP-0003162 NSN 4820-01-546-0523 Blocking valve Flow Control Valve EP-0003155 NSN 4820-01-480-5342 Bogie wheel Flow Control Valve EP-0002494 NSN 4820-01-480-5338 Cab movement Flow Control Valve EP-0002224 NSN 4820-01-550-5635 Boom folding

18 – 20. The Distribution Box part numbers EP-0008641 with NSN 6110-01-550-5639, EP-0008498 with NSN 6110-01-550-8342, and part number MP-0003217 with NSN 6110-01-550-5629 are weather resistant enclosures that house electronic components that control different functions of the RTCH. The enclosures house components such as switches, circuit breakers, connectors, and cables.

21 – 23. The Boom Section, Outer part number MP-0001950G, with NSN 3830-01-480- 2863, Boom Section, Inner part number EP-0002302, with NSN 3830-01-546-0710, and Boom Section Inner part number MP-0002302G with NSN 3830-01-546-0710 are the individual components of the RTCH lifting and elevating boom. These components are made of structural steel and have precise tolerances that allow the telescoping action of the boom.

24. The Turret Ring Assembly part number MP-0001603G and NSN 3830-01-558-5074 is a structural component that connects the RTCH boom to the top handler, enabling rotation of the top handler through its prescribed range of movement. This component is made of structural steel and has precise tolerances that allow connection of these components.

25 – 36. The Cylinder Assemblies (see table below) are actuated by hydraulic pressure and assist in performing a variety of machine functions. In general, the parts of a hydraulic cylinder include the cylinder barrel, the base or cap, the cylinder head, the piston, the piston rod, and the seal gland.
