Design

The BelAZ 75710 has a conventional two-axle setup but the wheels are doubled, one to an

axle An axle or axletree is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating around the axle. In the former case, bearing ...

turning radius The turning diameter of a vehicle is the minimum diameter (or "width") of available space required for that vehicle to make a circular turn (i.e. U-turn). The term thus refers to a theoretical minimal circle in which for example an aeroplane, a ...

of about . The 75710 is claimed to carry a load. With an empty weight of , it is much heavier than BelAZ's previous largest model, the 7560, 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
