The BelAZ 75710 is an ultra classhaul truck manufactured in Belarus by BelAZ. As of 2013, it was the world's largest, highest payload capacity haul truck.
The 75710 is claimed to carry a 450-tonne (440-long-ton; 500-short-ton) load.[3] With an empty weight of 360 tonnes (350 long tons; 400 short tons), it is much heavier than BelAZ's previous largest model, the 7560, which weighed 240 tonnes (240 long tons; 260 short tons) when empty.[4][5] It is 20.6 m (67 ft 7 in) long, 8.16 m (26 ft 9+1⁄4 in) high, and 9.87 m (32 ft 4+5⁄8 in) 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 65-litre (4,000 cu in) 16-cylinderfour strokediesel engines, each with 2,300 horsepower (1,700 kW). These are coupled to two ACalternators and four AC traction motors (two in each axle.)[6] Fuel consumption (according to company data) is 198 g/kWh (55 g/MJ), with the option to run on only one if carrying less than capacity loads. Maximum claimed speed is 64 km/h (40 mph), and economy maximum speed (when fully loaded and on a 10% gradient) is 40 km/h (25 mph).[7]
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.[8]
