The BelAZ 75710 is an ultra-class haul truck by Belarusian manufacturer BelAZ. At 450 metric tons (496 short tons), it is the world's largest, highest payload capacity haul truck.

Design

The BelAz 75710 has a conventional two-axle setup, but with dualled wheels (like a scaled-up International Payhauler 350), hence it needs eight 59/80 R63 tyres.[1] Unusually, it has four-wheel drive and four-wheel hydraulic steering. The turning radius is 20 metres.

The 75710 can carry a 450 metric tons (496 short tons) load.[2] The empty weight is 360 tonnes - much more heavily built than the previous model, which was 240 tonnes.[3] It is 20.6 metres long, 8.16 metres high, and 9.87 metres 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 (with AC/AC diesel-electric transmission based on the ELFA inverters) is powered by two 65-litre 16-cylinder diesel engines, each with 2,300 horsepower.[4] 2 engines working together give a power of 4,600 hp. This, in addition to the shallow bed, dualled tyres, and very heavy empty weight, has led to concerns about operating efficiency.

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.[5]

Project history

Soligorsk Construction Trust No. 3 built a new production building for BelAZ which will produce the 75710. Overall, BelAz is investing $644 million in increasing production capacity across its range.[6] The first truck was delivered to the Kuzbass 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]
