Design

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.[1] It also has four-wheel drive and four-wheel hydraulic steering which is unusual. It has a turning radius of about 20 m (66 ft).

The 75710 can carry a 450-tonne (440-long-ton; 500-short-ton) load.[2] With an empty weight of 450 tonnes (440 long tons; 500 short tons), it is much more heavily built than the previous model, which weighed 240 tonnes (240 long tons; 260 short tons) when empty.[3] 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 500 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.[4] Fuel consumption (according to company data) is 198 g/kWh (1.94 oz/MJ) per engine, with option to run on only one if carrying less than capacity loads. Maximum 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).[5]

Project history

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.[6] The first truck was delivered to the Kuznetsk Basin in 2013.

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.[7]
