DET-320 can used as a mini-power plants to provide electricity to small communities. The largest of the produced throughout the continent heavy bulldozer T-800 (T-75.01) working weight 106 tonnes, of which equipment has to 29.5 tons, is equipped with a 820-horsepower engine 6DM-21T with a turbocharged and intercooled. Hydromechanical transmission provides four forward gears and two – the rear and consists of a single-stage three-wheel torque converter, driveline, and module (three-shaft planetary gearbox and a rotation stop brake and a conical gear), hydraulic transmission, two-stage final drive with a pair of spur and planetary series. Disk clutches KP mechanisms rotation and stops the brakes are working in oil and require no adjustment. T-75.01 is designed to develop the most severe permafrost and rocky soils in the mining industry, to carry out large volumes of earthwork in road construction in various climatic conditions without carrying out blasting in overburden. Promtractor " (CHZPT) now offers three basic models of ARBs: T-25.01, T-35.01 and T 50.01 traction grades 25, 35 and 50, respectively. All machines are equipped with a planetary manual, three-point semi-rigid suspension with external oscillating axle trucks, which provides high traction properties and reduces shock loads on the undercarriage system. The first copies of the bulldozer T-25.01 were issued in 1985.
A few years later at its base were fabricated pipe-layer TG-321, and reclamation of TM-25.01. Repetitive production of T-25.01 only began in 1995. The bulldozer can be used in the industrial, oil & gas, hydraulic engineering, and mining for heavy earthmoving works, including the development of frozen and rocky ground.
