Palletized Load System (PLS) 10x10 Trucks and Trailer
M1075 10x10 Palletized Load System (PLS) cargo truck with M1076 payload trailer.
The PLS trucks have been called "Truck, Cargo, PLS," "Truck, Tractor, PLS" "Truck, Palletized Loading," or "PLS Truck" interchangeably. The three models of the Palletized Load System (PLS) 10x10 Trucks and Trailer are:
- M1074 Truck, Palletized Loading, 10x10 with Material Handling Crane and 20K winch
- M1075 Truck, Palletized Loading, 10x10 w/o Material Handling Crane
- M1076 Palletized Load System Trailer
The M1074 is equipped with a variable reach Grove PLS Material Handling Crane (MHC) to support forward-deployed artillery units. The M1075, without MHC, is used in conjunction with the M1076 trailer in support of transportation line haul missions. Without leaving the cab, the driver can load or unload the truck in less than one minute, and both truck and trailer in less than five minutes.
The M1076 Palletized Load System Trailer (PLST) is a three axle trailer designed to carry an 8x20-ft. M1077 flatrack (NSN 3990-01-307-7676) with a 16.5 ton payload. The flatrack is interchangeable between truck and trailer. PLST can accommodate both full and partially loaded flatracks. Guides laterally position the flatrack on the trailer while rear stops and locks secure the load and prevent the load from sliding rearward. The PLST is equipped with a two position adjustable drawbar and intervehicular connecting cables that attach the trailer to the towing truck.
The PLS prime mover features a central tire inflation system (CTIS) that significantly improves off-road mobility. Current NATO agreements require PLS to maintain interoperability with comparable British, German and French systems through the use of a common flatrack.
Two additional pieces of equipment enhance PLS flexibility. The M3/M3A1 Containerized Roll-in/out Platform (CROP) is an A-frame type flatrack which fits inside a 8x8x20-ft ISO container. A container handling unit (CHU) enables PLS to pick up and transport ISO containers without using a flatrack. Flatracks and CROP are interchangeable between PLS and the HEMTT-LHS.
Other types of bodies and specialized equipment are carried by the PLS trucks, based on standardized Engineer Mission Modules (EMM).
