RT240 Rough Terrain Container Handler (RTCH) Components

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 18 separate spare part components to support the Army’s RTCH fleet. The list of components included are listed below:

1. Mechanical Transmission - part number 9238920006, 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.

2. Hydraulic Motor - part number 9238990686, NSN 2540-01-520-7864 is the top-handler slewing motor. This component provides precise control for the top-handler for extension and retraction. The top-handler is the main attachment for the RTCH, enabling the engagement of ISO containers.

3. Parts Kit, Fork Lift - part number EP-0020139, 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 flat racks.

4. Material Hoisting Unit - part number 923853978, 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.

5. Hydraulic Pump - part number 9231410043, NSN 4320-01-480-4880 is a hydraulic pump that directs hydraulic flow for the steering and top-handler functions of the RTCH.

6-11. Flow Control Valves - part numbers A406750100, 920113047, 9238870001, 9235430034, 920129113, and 9235430020, with NSNs 4820-01-480-4846, 4820-01- 480-4860, 4820-01-480-4892, 4820-01-546-0523, 4820-01-480-4853 and 4820-01-480- 5339 include a variety of control valves that direct hydraulic flow to actuate several different functions in the RTCH. These functions include radiator fan control (A406750100), boom servo (920113047), steering control (9238870001), bogie wheel control (9235430034 and 9235430020), and boom functions (920129113).

12-13. Distribution Box - part numbers A487510100 and A326850400R, NSNs 6110-01- 550-5629 and 6110-01-550-8342 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.

14-15. Boom Section, Outer - part number A393860100, NSN 3830-01-480-2863, and

Boom Section, Inner part number A393870100, NSN 3830-01-480-3144 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.

16. Turret Ring Assembly - part number 9239762713, 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.

17. Cylinder Assembly - part number EP-0002125, NSN 3040-01-659-9993 is a component of the RTCH bogie wheel system. The bogie wheels are deployed by actuating the hydraulic cylinder, and are used to assist the machine to be loaded for aircraft transport. In general, the parts of a hydraulic cylinder include the cylinder barrel, the base or cap, the cylinder head, the piston, the piston rod, the seal gland, and the seal gland.

18. Cab Assembly - part number MP-0029790, NSN 2510-01-685-0698 is a replacement steel cab for the RTCH. It serves as a weather resistant operator enclosure with glass windows on four sides and the roof.
