M932A2 Semi-tractor. The M931 (M932 w/winch) was a semi-tractor used to tow semi-trailers up to 37,500 pounds (17,000 kg). A front-mounted winch was optional. Unlike commercial trucks the fifth-wheel could also pivot side to side, making a more flexible connection to the trailer. Even so, off-road performance was limited. [14]
The M970 Semi-Trailer Refueler is a 5,000-U.S.-gallon (19,000 L; 4,200 imp gal) fuel dispensing tanker designed for under/overwing refueling of aircraft. It is equipped with a filter/separator, recirculation system and two refueling systems, one for underwing and one for overwing servicing.
The M15A2 was the trailer that the M123 was intended to tow. It had a higher load plate and larger coupling pin than a standard semi-trailer. Early M123 had a larger fifth wheel mounted above the frame rails, but as more standard trailers were used, the M123C and all following models had lowered fifth wheels.
Semi-tractor/trailers have to stay on relatively flat ground, and are not rated for full off-road use. On improved roads they could tow up to 55,000 lb (25,000 kg) with 25,000 lb (11,000 kg) on their fifth wheel. [7] [14] Tractor trucks normally towed a 12-ton, 2-axle trailer. There were stake and platform, van, low-bed, and tanker bodies.
A conventional ladder frame has a front steering axle with a 12,000 lb (5,400 kg) weight rating and tandem rear axles with a 40,000 lb (18,000 kg) weight rating. The truck can have a maximum weight of 52,000 lb (24,000 kg), including a 30,000 lb (14,000 kg) load. The total weight rating of the truck and trailer is 105,000 lb (48,000 kg).
The U8144T tractor was used to tow semi-trailers with 10-ton or 25-ton ponton bridging equipment. Directly behind the cab was a large toolbox. [25] [26] 2,711 were built between 1941 and 1945, of which 42 went to the Soviet Union under the Lend Lease Act. [27] The U8144 had a similar chassis with van bodies built by York-Hoover.
