World's Largest Dump Truck (Belaz 75710)

The BeLAZ 75710 is an ultra class dump truck manufactured in Belarus by BeLAZ. As of 2006, it is the world's largest, highest payload capacity haul truck.

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 31 meters.

The BeLAZ 75710 can carry a 450-tonne (440-long-ton; 500-short-ton) load. 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. It is 20.6 meters long, 8.16 meters high, and 9.87 meters 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. These are coupled to two AC alternators and four AC traction motors (two in each axle). 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 claimed speed is 64 km/h, and economy maximum speed is 40 km/h.
