Design
editThe BelAZ 75710 has a conventional two-axle setup but the wheels are doubled, one to an axle, imitating the 1950s International Payhauler 350. For this reason, it needs two 59/80R63 tires.[1] It also has four-wheel drive and four-wheel hydraulic steering which is unusual. It has a turning radius of about 31 m (102 ft).[2]
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-cylinder four stroke diesel engines, each with 2,300 horsepower (1,700 kW). These are coupled to two AC alternators 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
editBelAZ 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]
Previously the world's largest haul trucks were the Bucyrus MT6300AC, Liebherr T 282B and Caterpillar 797F ultra-class trucks, with load capacities of 400 short tons (360 t).[9]
