The M1120 Heavy Expanded Mobility Tactical Truck (HEMTT) is a standard U.S. military forward resupply vehicle in the up to 140,000 lb GVW class. The M1120 HEMTT Load Handling System (LHS) has the same load handling system as the newer M1074/M1075 Palletized Loading System (PLS) vehicles. It allows the vehicle driver to load and unload cargo without any additional material handling equipment, and without leaving the vehicle cab.
The M1120 HEMTT LHS consists of a standard HEMTT M977, M978 or M985 chassis equipped with an integral load-handing system providing self-load/unload capability and capable of transporting an 11-ton payload. LHS carries equipment/ammunition/supply loads on demountable “flatrack” cargo beds and is able to tow an 11-ton payload trailer also capable of carrying flatracks. The containerized roll-in/out platform (CROP), an A-frame type flatrack that fits inside a 20-foot International Standards Organization (ISO) container, gives the HEMTT LHS added cargo carrying capability. Flatracks and CROPs are interchangeable between HEMTT LHS and the M1074/M1075 PLS trucks. M1120 HEMTT LHS can also be used with the M1076 Palletized Load System Trailer.
The HEMTT without trailer is 66,000 lb GVW and the trailer adds just under another 37,000 lb. Maximum axle loadings are 20,000 lb which are within current design parameters for U.S. Federal highways. Therefore, the M1120 HEMTT may legally travel on public roads throughout the United States.
The NSNs for the HEMTT LHS variants are:
M1120 NSN 2320-01-471-1326
M1120A2 NSN 2320-01-492-8221
