SNOW-and MARSH-GOING CHASSIS
521 M1


The design of this chassis is substantially modified basing on the experience of operating over 450 vehicles of this range in Western Siberia, Far North and Far East.
Enlarged, 7-wheel vehicle base makes it possible to increase its load-carrying capacity.
The vehicle is fitted with a commonly used diesel engine YaMZ-238BV (310 hp/228 kW).
Tracks (700 mm wide) with rubber-and-metal joints have longer service life.
4 car headlights (2 on cabin roof) widen field of view at night.
A searchlight controlled from the cabin ensures additional orientation convenience.
Enforced vehicle hull front protects the crew at running over obstacles and considerably reduces `bulldozer effect` when moving over loose snow and ground.
A low-pressure car pneumatic system.
A winch with rated load 6 - 8 tonnes.
A power take-off drive makes it possible to mount a welding generator and two hydraulic pumps-one for driving the winch, another-for additional technological equipment.
At customer's request the chassis may be fitted with welding equipment.

It is intended for mounting various technologic equipment (tanks, containers, freight bodies, passenger saloons, etc) and serves as a base for special-purpose vehicles with high cross-country capability.

Better labour and rest conditions for a driver and crew are provided by:

  • 2 berths;
  • updated instrument board with car testing instruments;
  • updated vehicle steering system with hydraulic and pneumatic actuators on levers and pedals.
  • comfort in cold seasons is ensured by a 2-stream heating system:
      a) making use of engine heat
      b) an independent 2-mode heater
