Earthmoving manufacturer aims for record dump

Chief designer of BelAZ?s mining vehicles Leonid Trukhnov said that the 75710 is the world?s first 496-tonne manufactured mining truck and the company has submitted the necessary documentation to claim a Guinness World Record breaking the earlier record held by German manufacturer Liebherr.

The BelAZ 75710 became the world?s largest mining two-axle, all-wheel-drive dump truck when it rolled out of the BelAZ plant in late 2013.

It is powered by a Siemens AC traction drive system, the MMT500 that has four 1200kW electric motors, two traction generators, three blowers, a brake resistor unit and a control cabinet with two ELFA inverters.

As opposed to its predecessors, the new dumper is provided with eight wheels, each designed for about 100 tonnes of load.
The traction motors for the electric gear were manufactured at Siemens facilities in N?rnberg and the company supplies BelAZ with AC traction electric drives for 240-tonne and 360-tonne dump trucks.

The BelAZ 75710 is more than 20 metres long, nearly 10 metres wide and eight metres high. The turning diameter is about 20 metres with a maximum speed of 64 km/h.

The truck is in high demand in the mines of Kuzbass region of the Russian Federation and in certain coal strip mines of Chile and North America.
