For all those who have to transport people or material, the Siberian expanses poses a vital problem: the endless expanses are only at all crossable in the Winter, when the ground is frozen and even the rivers and lakes are transformed into an ice motorway. As soon as the warmer seasons come around, the top layers of soil thaw and it becomes wet and abysmal.
Avtoros Shaman - the swamp conqueror
These unending swamplands have challenged the Russian spirit of invention for centuries. People have tried to overcome the Tundra with track and chain drives, and even with bizarre screw turret chassis'. Monstrous low pressure tyres have now proven themselves to be the ideal compromise with regard to economy and retrofitting effort, with which even adventurously jacked up Lada Nivas can get astoundingly far in the swampy terrain.
Moscow-based vehicle manufacturer Avtoros has also been addressing the topic of balloon tyres. Based around the gigantic special tyres developed by Avtoros themselves, 1.2 metres tall and more than half a metre wide, they built an 8x8 off-road transporter that is more than capable.
The Avtoros Shaman 8x8 is driven by a modern Iveco turbo diesel engine. The three-litre engine produces 168 HP and can accelerate the Avtoros Shaman 8x8 to up to 80 km/h. With this, the Avtoros Shaman 8x8 is also considerably more nippy and is more efficient than weighty and consumption-heavy chain vehicles. As an option, Avtoros also installs Hyundai engines - a 128 HP petrol engine and two diesel engines with 176 and 237 HP respectively.
Owing to the construction of the special tyres, with low air pressure and a huge contact area, the ground pressure of the Avtoros Shaman 8x8 is extremely low. The four-axle vehicle, which still weighs up to four tonnes, therefore doesn't sink into bog meadows, but rather drives over the top.
Avtoros Shaman 8x8 - 6.3 metres long
The dimensions are impressive: the Avtoros Shaman 8x8 is 6.2 metres long, 2.5 metres wide and 2.7 metres tall. With its monster tyres, it also offers handsome ground clearance: 450 millimetres. For the axle construction, Avtoros uses non-variable parts: four double-wishbone axles are flange-mounted to the central frame on the left and right, driven by free-spinning full-floating axles. This design has two advantages: the management of replacement parts is much simpler due to the identical construction of all wheel suspensions. And all wheels can be steered.
Each axle can be pivoted in the desired direction as required. Whether walking sideways like a crab or in opposite directions for a small turning circle, there are a host of possible applications. All axles have differential locks. In the Avtoros Shaman 8x8 the driver sits in the middle, in a central cockpit, and steers the vehicle using a conventional steering wheel. Up to nine seats or a large storage space can be installed behind the pilot as required. Depending on the road surface, the Avtoros Shaman 8x8 can carry up to 1.5 tonnes. Empty, the Avtoros Shaman weighs just 2.5 tonnes.Sensational angle values
The construction, with a small distance between the front and rear pairs of axles, enables a very generous slope angle, while the low rear and the negative front overhang enable a spectacular slope angle. This means that the Avtoros Shaman 8x8 is not deterred by extreme hills or steep ditches, as it always has at least four wheels in contact with the ground. A winch on the front provides additional safety.
The Avtoros Shaman 8x8 features a lightweight construction with a mix of aluminium and plastic. The engine, which is protected, is positioned right at the top within the central frame and features an auxiliary power take-off. This also drives a folding propeller to the rear of the vehicle, as the Avtoros Shaman 8x8 can also swim. It can move through the water with a maximum speed of 7 km/h.
