Light Tactical Trailer Heavy Chassis (LTT-HC)

The Light Tactical Trailer Heavy Chassis is a single axle, two wheel trailer designed to be towed by a HMMWV towing vehicle. The high ground clearance LTT-HC chassis is available as a platform intended to be the basis of mobile tactical systems. As noted on the page devoted to the description of those systems derived from the Light Tactical Trailer as a platform, the combination of LTT-HC and its HMMWV prime mover is very attractive for modular Shop Sets, electronics, shelters, and many other systems that can benefit from the load capacity and mobility specifications.

Tactical systems for the U.S. Marine Corps are supported by the Light Tactical Trailer - Marine Corps Chassis (LTT-MCC) also based on the LTT-HC chassis.

The Light Tactical Trailer Heavy Chassis has the same tires, wheels, and track width as the High Mobility Multipurpose Wheeled Vehicle (HMMWV).

A hand-brake lever and cable assembly located on each side of the trailer activate a service brake at each wheel. Control of each service brake is independent. In addition to handbrake-activated service brakes, the trailer is equipped with an inertia-actuated hydraulic brake system (surge brakes). The trailer suspension consists of one shock absorber on each end of the axle. Two stabilizers, stored in the front and installed in the rear, provide stability when the trailer is not coupled to a towing vehicle.

The data listed on the Trailer Chassis Identification and Shipping Plates is different from both the M1101 and M1102 trailers. In addition, the trailer chassis has no cargo body. The nomenclature and NSN is Chassis, Trailer: 2-Wheel (NSN 2330-01-387-5424).
