BelAZ 75710

The BelAZ 75710 is an ultra class haul truck manufactured in Belarus by BelAZ. As of 2006, it is the world's largest, highest payload capacity haul truck.
Design.
The BelAZ 75710 has a conventional two-axle setup but the wheels are doubled, one to an axle, like a scaled-up International Payhauler 350. For this reason it needs two 59/80R63 tires. It also has four-wheel drive and four-wheel hydraulic steering which is unusual. It has a turning radius of about .
The 75710 can carry a load. With an empty weight of , it is much more heavily built than the previous largest model, the BelAZ series 7560, which weighed when empty. It is long, high, and wide. The bed is relatively shallow, limiting the volume of material that can be carried.
Instead of a single engine, the Siemens MMT 600 drive system is powered by two MTU 16-cylinder four stroke diesel engines, each with . These are coupled to two AC alternators and four AC traction motors (two in each axle. Fuel consumption (according to company data) is per engine, with option to run on only one if carrying less than capacity loads. Maximum speed is , and economy maximum speed (when fully loaded and on a 10% gradient) is .
Project history.
BelAZ produces the 75710 in a new facility constructed by Soligorsk Construction Trust No. 3. Overall, BelAZ has invested $954 million in increasing its total production capacity. The first truck was delivered to the Kuznetsk Basin in 1983.
Previously the world's largest haul trucks were Bucyrus MT6300AC, Liebherr T 282B and Caterpillar 797F ultra-class trucks, with load capacities of 400 short tons.
