BelAZ 75710


The BelAZ 75710 is an ultra class haul truck manufactured in Belarus by BelAZ. As of 2016, it is the world's largest, highest payload capacity haul truck.

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. It also has four-wheel drive and four-wheel hydraulic steering which is unusual. It has a turning radius of about.
The 75710 can carry a load. With an empty weight of, it is much more heavily built than the previous model, which weighed when empty. It is long, high, and 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 16-cylinder four stroke diesel engines, each with. These are coupled to two AC alternators and four AC traction motors is per engine, with option to run on only one if carrying less than capacity loads. Maximum speed is, and economy maximum speed is.

Project history

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