The Nizhny Novgorod company Technoservice designed and manufactured a 24-seater vehicle for transporting miners by order of Uralkali. “Mole” T-3220 - the novelty got such a name - uses the shortened chassis of the PAZ-3205 bus with single-wheel rear axle wheels.
The driver's cab and passenger compartment are made in the form of removable modules; Before assembling the machine, they are lowered separately into the shaft of the mine with a cross section of 3.50 x 1.45 m. The Japanese engine is a four-cylinder atmospheric diesel Toyota-5L. The remaining components and assemblies from domestic cars: the power steering and hydraulic pump are KAMAZ, the radiator was borrowed from the Volga GAZ 3102, the gearbox and razdatka from the GAZ-66. The latter allows you to reduce the operating speed range to 2–57 km / h (in mines there are restrictions: 20 km / h and only with a special permission of 40 km / h) and create all-wheel drive modifications for working in strongly inclined corridors - this will be one of five machines ordered by Technoservice.
Of the special equipment - an automatic fire extinguishing system "Doping-2", double exhaust gas treatment - a catalytic converter and then a bubble tank. Incidentally, the latter makes a silencer unnecessary. The underground bus can also move along public roads, as it is equipped with all the necessary lighting equipment. The cost of the “Mole” is supposedly 25-30 thousand dollars, which is three to four times cheaper than foreign counterparts.
