Tracked snowmobile transporter for cargo transportation on unpaved roads and terrain, including snowy off-road, overwatered and swampy terrain.
Development of the all-terrain vehicle was started in 1970 on the basis of the NAMI-0157M heavy-duty snowmobile. In 1976, a pilot batch was produced, which passed preliminary, acceptance and control tests. In 1977, the acceptance committee recommended the all-terrain vehicle to be put into serial production.
In 1981, all design documentation was transferred to the preparation of production and the first pilot batch was produced. In 1984 the rover was demonstrated at the All-Union Exhibition of Economic Achievements of the USSR. In the early 1990s, in accordance with the economic situation, orders for this product and, as a consequence, production ceased.
The snowmobile was put on four relatively short tracks, which allowed the rover to perform more complex maneuvers.
- load capacity of the SSBT is 8 tons
- gross weight – 22500 kg
- average specific pressure on the track surface of a loaded transporter – 0.22 kg/cm2
- maximum speed – 30 km/h
- control fuel consumption – 100 l/100 km
- maximum traversable hill – 58 %
- depth of ford – 1.8 m
- nominal engine power – 210 hp.
The snowmobiler is made according to the “wagon” scheme, where the frame with the engine and cabin is mounted on two caterpillar tracks, which rotation around the vertical axes and rocking in the longitudinal direction provides the required steerability and ability to move on uneven surfaces of the track.
For increased cross-country ability in the driving axles are installed worm-screw differentials of increased friction. The transfer case is made with a symmetrical differential. Torsion suspension provides good smoothness of movement, support rollers are of automotive type, their tires are filled with sponge mass instead of air – they are not afraid of punctures. Track blades are reinforced with metal cables, which ensures sufficient strength and low stretch.
