The BelAz 75710 has a conventional two-axle setup but the wheels are doubled, four to an axle, like a scaled-up International Payhauler 350. For this reason it needs eight 59/80R63 tires. It also has four-wheel drive and four-wheel hydraulic steering which is unusual. It has a turning radius of about 20 meters.
The 75710 can carry a 450 metric ton (496 short ton) load. With an empty weight of 360 tonnes, it is much more heavily built than the previous model, which weighed 240 tonnes when empty. It is 20.6 meters long, 8.16 meters high, and 9.87 meters wide. The bed is relatively shallow, limiting the volume of material that can be carried.
Instead of a single engine, the Siemens MMT 500 drive system is powered by two MTU 65-litre 16-cylinder four stroke diesel engines, each with 2,300 horsepower. These are coupled to two AC alternators and four AC traction motors (two in each axle). Fuel consumption (according to company data) is 198 g/kWh per engine, with option to run on only one if carrying less than capacity loads. Maximum speed is 64 km/h, and economy maximum speed (when fully loaded and on a 10% gradient) is 40 km/h. The complex propulsion system, in addition to the shallow bed, doubled tires, and very heavy empty weight, has led to concerns about operating efficiency.
BelAZ produces the 75710 in a new facility constructed by Soligorsk Construction Trust No. 3. Overall, BelAz has invested $644 million in increasing its total production capacity. The first truck was delivered to the Kuznetsk Basin in 2013.
