BelAZ 75710 the largest dump truck in the world

Not long ago, the place of his permanent job in one of the quarries in Siberia, Russia, arrived new huge mining truck that can transport cargo weighing up to 450 tonnes, which is equivalent to the weight of 350 cars of the middle class. This dump truck, the BelAZ 75710 will be awarded the rank of the largest dump truck in the world, taking the place of his predecessor, dump truck BelAZ 75600, the lifting capacity of 320 tons.

The BelAZ 75710, whose length is 20.6 meters and a width of 9.75 meters, height — 8.17 meters and a weight of 360 tons, is supported by eight wheels, tires 59/80R63 can withstand the weight to 810 tonnes. Moving without a load, the truck can reach a maximum speed of 64 kilometers per hour. But what even more distinguishes the BelAZ 75710 from other similar vehicles is its electric propulsion Siemens MMT500.



To create the electric powertrain for the new truck were involved in a famous German company Siemens, the specialists of which have a very rich 15-year experience in establishing power plants for the transport and equipment of mining industry.

Dump truck BelAZ 75710, the first prototype of which was assembled in the fall of 2013, driven by four electric motors AC 1TB3026−0G-03, located in each of the four wheels. The capacity of each of the motors is 1,200 kW, and the energy required for their work produced two of the traction generator YJ177A, with a capacity of 1704 kW, which rotate separate 16-cylinder diesel engines, MTU DD 16V4000, with a capacity of 2330 HP (1715 kW) each.

The equipment dump truck BelAZ 75710 comes with an innovative control system of distribution of energy supplied to the motors. This system implements intelligent energy distribution between the two axles of the truck, thanks to her, the same truck can continue moving even in the event of failure of one engine.

According to information published by representatives of the Belarusian automakers, all the new technology and unique engineering solutions used in the construction of dump truck BelAZ 75710 has achieved outstanding economic performance during its operation. The cost of transporting one ton of cargo by 25 percent lower than the cost of transportation any other mining truck. In addition, dump trucks BelAZ 75710 was originally calculated for the continuous mode of operation and with all the quite strict environmental norms.
