EQUIPMENT CHARACTERISTICS
The HET Tractor is used in combination with the M1000 Trailer to form the Heavy Equipment
Transport System (HETS). The HETS is used to load, unload, and transport the M1 Series
Main Battle Tank (MBT) and other heavy tracked/wheeled vehicles weighing up to 140,000
lbs (63 560 kg) during administrative and tactical operations.
EQUIPMENT CAPABILITIES
1. Operates in temperatures from -25 to 120°F (-32 to 49°C) in normal configuration
(arctic kit not installed) and -50°F to 120°F (-46°C to 49°C) with arctic kit installed.
2. Fords water up to 28 in. (71 cm) deep for 5 minutes without damage or requiring
maintenance before operation can continue.
3. Normal operating range is 325 mi (523 km), based on 250 gal. (946 L) of fuel and
231,400 lbs (105 056 kg) gross combination weight rating (GCWR) when operated
at an average speed of 30 mph (48 km/h). Varying loads, prolonged idle, use of
Power Takeoff (PTO), off-road driving, and climatic conditions affect operating
range.
4. Tiedown points are located so HET Tractor can be restrained in all directions during
air transport in C-5A and C-17 aircraft. HET Tractor is also capable of being
transported by highway, rail, and sea.
EQUIPMENT FEATURES
1. Eight-cylinder, 736 cu in. (12.1 L), V-type, 2-cycle, turbocharged diesel engine.
2. Automatic transmission with one reverse speed and five forward speeds.
3. Operator-controlled 6-wheel/8-wheel drive with high and low range transfer case
for positive traction on unimproved road surfaces.
4. Power steering system consists of basic manual steering system with hydraulic
boost. An auxiliary steering pump provides hydraulic boost in the event of main
pump failure. Mechanical linkage also provides operator control in event of
hydraulic oil pressure loss.
5. Fuel system includes two fuel tanks, injectors, pipes (inlet and outlet), manifolds
(integral with the cylinder head), pump, fuel/water separator, secondary filter, and
fuel lines.
6. Two front and two rear towing eyes.
7. Manual-release pintle hook which will allow towing of trailer.
8. Two main winches, each having 55,000 lbs (24 970 kg) capacity, used for
recovering, loading, and unloading heavy tracked/wheeled vehicles. Auxiliary
