The DT-10P and DT-30P ATVs are widely used by Russian troops deployed in challenging environmental regions, on islands (for transporting army elements, ammunition, equipment, FOLs and installation of weapon systems).Because of low ground pressure,vehicle is theoretically immune to certain types of AT mines. ATVs are indispensable as recovery vehicles, since they have a high pull ratio (approximately 500 kN for the DT-30P) and can approach a stuck or damaged vehicle from any direction in bad road conditions. The DT-10P and DT-30P transporters are very efficient as part of search and rescue teams operating in extreme conditions (bad roads, floods, snow-drifts, land and snow slides and large-scale destruction) when it is necessary to evacuate people, animals, and various cargoes up to 30 ton by weight, or transport rescue teams, medical personnel, various equipment and food to the affected area.
The transporters models feature similar configuration. Both units are basically sealed all-welded structures.The vehicle power plant is arranged in the first van behind the driver's cabin. From a 12-cylinder multi-fuel engine the torque is conveyed to a hydro-mechanical transmission via a cardan shaft and further to the bevel gearing and final drive units, as well as to the drive sprockets of the first and second van bodies.
The track assembly is made up of four wide rubberised-fabric band tracks reinforced with welded steel cross-pieces; four track guide engagement drive sprockets with nine pairs of polyurethane rollers; road wheels with rubber bands, and four idler wheels (one on either side is provided with a polyurethane rim). The suspension is independent, torsion-bar type, with spring supports on all rollers.
Years of operation of these vehicles have proved their reliability and robust design. The vehicle design primarily features an unconventional pattern of four active track envelopes providing for large surface contact with the ground for greater stability. In addition to this feature, these ATVs ensures the so-called "kinematic method" for turning the articulated tracked vehicle through the "forced folding" of its units. The kinematic method of turn provides a positive tracking force for all tracks during linear movement and while making turns. A combination of the kinematic method of turn and a powerful multi-fuel engine, along with a hydro-mechanical transmission, unique track and suspension system with wide band tracks, road wheels with rubber pads, and vertical hydraulic cylinders which allow the two vehicle units to move vertically in relation to each other, make the articulated vehicles with a maximum weight of up to 60 tons more capable in terms of their sand/loose soil/snow-going capacity,than any type of single-unit vehicle.
As the two units can be turned relative to each other in the vertical and horizontal planes via hydraulic cylinders or, conversely, can be fixed, the two-unit vehicle can move over short (equal to the length of one unit) sections of difficult terrain and obstacles like ditches and walls and come out of water onto an unprepared bank,ice,or peat.
