The Two-link conveyor tractor 3344-20 is designed for transportation of people and various cargoes in difficult terrain and off-road conditions. The vehicle is capable of transporting up to 17 people or 3 tons of cargo. Low, even less than that of a person, the average specific pressure on the ground (no more than 0.25 kg / cm2) provides a high supporting permeability of the conveyor tractor 3344-20 practically in the most difficult terrain conditions: in swamps, on loose snow, on sands, in wooded and swampy areas, etc..

The vehicle is equipped with a Russian-made in-line turbodiesel with a maximum power of 240 hp. The engine is connected to an automatic transmission, which reduces the driver's fatigue during long marches, and provides a good ride. The volume of fuel tanks provides a two-link transporter with a cruising range of up to 450 km.

The ability to cross water obstacles by swimming makes the Two-link conveyor tractor 3344-20 an indispensable aid for emergency responders in crisis situations, such as extensive snow drifts or floods. The curb weight of the vehicle, not exceeding 11 tons, allows the vehicle to be transported by any means of transport, including transport helicopters, which ensures high maneuverability of the structures operating it. The Two-link conveyor tractor 3344-20 can be carried out as a medical option for evacuating the sick and wounded and providing medical assistance to them on the move.

Depending on the area of the vehicle operation, at the customer’s request, either additional heaters or an air conditioning system in the cabin can be installed on it.

The Two-link conveyor tractor 3344-20 was accepted for supply by the Russian army, where it is used to transport personnel with full Arctic ammunition and service weapons, military equipment, towing artillery systems and trailers in units of combat, logistical and medical support of types and branches of the Armed Forces of the Russian Federation under any climatic conditions.

The tracked two-link conveyor tractor has the ability to install various small arms and other weapons, special equipment.
