SIVER 6×6 — Heavy Off-Road Vehicle with Payload Capacity up to 5 Tonnes
The SIVER 6×6 is a heavy wheeled off-road vehicle based on the GAZ Sadko NEXT chassis, designed for transporting cargo and equipment over difficult terrain. Full-time 6×6 all-wheel drive, portal axles with in-house-designed wheel reduction gears, and a payload capacity of up to 5 tonnes make the vehicle suitable for industrial logistics, expedition, and special tasks.
1. Payload Capacity up to 5 Tonnes
The SIVER 6×6 is designed to transport heavy loads in conditions where route accessibility is limited by road conditions, soil, terrain, and seasonal factors.
A payload capacity of up to 5,000 kg allows equipment, materials, supplies, and necessary cargo to be delivered directly to the work site, reducing the need for intermediate reloading.
2. Six Driven Wheels — Traction on All Axles
The 6×6 wheel arrangement ensures traction is transmitted to all three axles. This helps realize the vehicle's capabilities on difficult sections of the route, while load distribution between the three axles is important when transporting heavy cargo.
This layout is suitable for operation on dirt roads, in forested and swampy areas, on snow, and other difficult surfaces.
3. In-House-Designed Portal Axles
The SIVER 6×6 is equipped with portal axles with in-house-designed wheel reduction gears.
The portal design allows the axle housing to be positioned higher relative to the wheel axis and increases ground clearance. The wheel reduction gears also provide additional gear reduction and help realize the vehicle's traction capabilities.
Combined with full-time 6×6 all-wheel drive, this forms the structural basis for movement over difficult terrain.
4. GAZ Sadko NEXT Chassis
At the heart of the SIVER is the GAZ Sadko NEXT truck chassis, adapted for operation as part of a heavy off-road vehicle.
The YaMZ-53443 diesel engine and transmission with a transfer case ensure the vehicle operates under load. Specific parameters of the power unit and transmission are indicated in the technical specification table of the current configuration.
5. Body and Configuration Options
The SIVER 6×6 can be equipped with an all-metal cabin with a cargo platform or a passenger body.
Depending on the purpose, cargo, cargo-passenger, and passenger versions are available. Cabin insulation and additional heating equipment allow the vehicle to be adapted for operation in cold climates.
6. Equipment for Operation in Difficult Conditions
The standard configuration includes solutions for daily operation and crew comfort:
- engine preheater;
- additional cabin heater;
- suspended driver's seat;
- roof hatch;
- airbags;
- heated mirrors and seat;
- power windows;
- cabin insulation.
Optional equipment includes:
- electric winch;
- central tyre inflation system;
- autonomous heater;
- searchlight;
- roof rack;
- protective equipment;
- snorkel;
- GLONASS/GPS navigation equipment;
- and other options.
The equipment composition is selected according to operating conditions and the customer's tasks.
7. Applications of the SIVER 6×6
The off-road vehicle can be used for:
Heavy Cargo
Transportation of heavy equipment and materials.
Remote Facilities
Supplying remote industrial facilities.
Oil, Gas, and Energy
Operation in the oil, gas, and energy industries.
Expeditions
Geological exploration and expedition work.

5 tonnes off-road — a unique payload capacity among wheeled off-road vehicles
The SIVER 6×6 occupies a unique niche in the market. Most wheeled snow-and-swamp vehicles in Russia and abroad are designed to carry 500–1,500 kg. For larger cargoes, tracked vehicles or heavy engineering equipment are usually used, which require route preparation.
The SIVER 6×6 removes this limitation: a combination of payload capacity up to 5,000 kg and the mobility of a wheeled off-road vehicle allows full-scale engineering cargo to be delivered where a standard truck cannot pass. Among wheeled off-road vehicles, such specifications are extremely rare — this makes the SIVER a unique logistics tool.
Why does 6×6 handle heavy loads?
The 6×6 wheel arrangement is more than just extra wheels. Three driven axles allow traction to be distributed between six wheels, and the load from the vehicle and the cargo being transported — between three axles.
For a heavy off-road vehicle, this is especially important: the design is intended not only for movement over difficult surfaces but also for transporting significant mass. It is precisely the combination of the 6×6 layout, in-house-designed portal axles, and payload capacity up to 5 tonnes that defines the purpose of the SIVER.
SIVER 6×6 — Heavy Equipment for Difficult Routes
The SIVER was created for tasks where high payload capacity, mobility, and the ability to deliver equipment and materials directly to the work site are important. A payload capacity of up to 5 tonnes makes it a solution for industrial logistics and operation in conditions where the capabilities of standard cargo transport are limited.
