The Zavolzhsky Crawler Tractor Plant owned by GAZ Group has been producing all-terrain vehicles since 1973, both for the army and for oil production, energy and other industries operating in remote areas of our country. Until recently, in the ZZGT model range there were only single-link all-terrain vehicles - the latest GAZ-3344 became the first two-link. By design, it resembles the famous “Knights”, more precisely, the youngest of Ishimbay models with the same lifting capacity of two tons. Another feature of the Zavolzhsky all-terrain vehicle is tracks with rubber shoes that allow traffic on the highway without damaging the asphalt. Moreover, the shoes are easily removable, and when worn, they can be replaced without removing the track. However, to do this in the field is not necessary at all: on the snow and soft ground the shoes will last until the car is overhauled, and even with regular driving on asphalt they will cover several thousand kilometers.

The width of the all-terrain vehicle is a little more than two meters (the same as, for example, GAZelle), which gives a number of advantages. For example, on forest roads, cut into account the width of the Belarus tractors, that is 1.6–2 m. Or when driving along the railway line: an often abandoned or active branch laid through an embankment through swamps or impassable thicket is the only way to the village. By the way, that is why the designers made the GAZ-3344 gauge almost equal to the five-foot railway used in Russia. The Zavolzhsky two-link will comfortably ride exactly on the rails, without slipping and damaging them thanks to the rubber “shoes”, while a wide 30-ton all-terrain vehicle will be forced to roll along the slope of the embankment, risking to tip over, periodically cutting small trees and, accordingly, shaking from strokes. The power plant includes a Chinese-made Cummins 4ISBe diesel engine with a capacity of 185 liters. with. Power system - with turbocharging and fuel injection at a pressure of 1800 bar from a common rail Common Rail. The fuel system components are from Bosch. Transmission - hydromechanical 5-speed Allison 2500. Tracked formula - 4x4, that is, all leading. Through the transfer case, the torque is transmitted by the cardan shafts to the bridges of each link. The hulls of both links (the so-called “boats”) are hermetically welded from steel sheet, which ensures buoyancy to the machine. The mover on the water is the tracks of both links, the speed afloat is up to 6 km / h. Transmission shafts emerging from the hull of the boat to the outside are sealed, and the suspension torsion bars pass inside the pipes welded across. For a uniform load on the tracks, the drive axles are located in front of each link, for the same purpose most of the units (engine, gearbox and transfer case) are located in the front link, and the payload is mainly in the rear. The two-link scheme provides a lot of opportunities that are not available to single-link machines. If there is a lack of adhesion to the ground, the tracks of one link (for example, on a steep but short rise) are pulled by it or, conversely, pushed out by a horizontally located other. Having blocked the hinge connecting the links, hydraulic cylinders and drawbars of both links, we get a rigid triangle - we can temporarily turn the machine into a long single link, able to move a trench of three meters wide and any depth.
