They are used on mountain development (mining open pit), in hydraulic engineering, irrigation and road construction, industrial landfills with large amounts of landfill. We nice to know that Russia produces equipment such elite class, and here it should be noted that the ussr was one of the first bulldozers began producing the severe category. Now these ARBs manufactured at two plants – CTZ-Uraltrac and Promtractor. oao "Chelyabinsk Tractor-Uraltrac in the severe category currently produces two models of traction class 25 – it's DET-250M2 and DET-320B1R2 with electromechanical transmission and one bulldozer tractive class of 75 – T-800 (T-75.01). DET-250M2 is done with the 1961-th, and for all years of graduation, he established himself on the positive side, however, share two-block Diesel B-31m2, designed for other types of machinery does not reach the level of foreign counterparts. DET-250 sets of four bulldozer blade: two production chsdm (formerly CHZK) and two of its own production. Since 1983, the Chelyabinsk tractor-produced tractor DET-350, in a production program in 2002, he was replaced by Bulldozer DET-320. Unlike its predecessor, DET-320 is equipped with a diesel engine YMZ-7512.10-04 with a lot fewer hours lifespan and fuel consumption.
To prepare the engine at an ambient temperature below -20 C along with the electric-device used liquid heater PKP-30E. Suspension system – with a torsion bar suspension with torsion stiffness equal to the incorporation into the frame instead of running trucks tractor frame. Closed type idlers made piece. Double quick-cab provides a good overview of the working equipment is equipped with a heater Air Heater type air-conditioning and double glazing.
