MINSK, 17 May (BelTA) – New haul trucks BelAZ-75589 with alternating-current electromechanical transmission were put to use by several coal-mining enterprises in Krasnoyarsk Territory, Russia in the last few months, the press service of the truck manufacturer told BelTA.
According to BelAZ, these are a brand new type of vehicles for Krasnoyarsk Territory coal-mining enterprises. They previously used 90-tonne haul trucks of foreign make and only with hydromechanical transmission. BelAZ haul trucks with the carrying capacity of 90 tonnes and with a 1,224hp engine and electromechanical transmission are designed to replace the competitors, which have withdrawn from the Russian market. The experience of operation of haul trucks of this capacity demonstrates that electromechanical transmission can offer better traction performance, speed and braking parameters. Electromechanical transmission improves the vehicle's operational reliability and hauling performance while reducing maintenance and repair costs, which means the cost of owning the haul truck as a whole.
The Krasnoyarsk Territory coal-mining enterprises, which have already tested the new vehicles, say that BelAZ-75589 with electromechanical transmission are reliable, productive, and fuel-efficient. They can easily handle slopes because electric motors allow the entire transmission to operate without slippage while electrodynamic braking in power generation mode while going downhill prevents wheels from slipping.
The public joint-stock company (OAO) BelAZ is the managing company of the holding company BelAZ. BelAZ is the world's largest manufacturer of haul trucks and transport equipment for the mining industry and the civil engineering industry. BelAZ occupies about 30% of the world market of haul trucks with an extremely large carrying capacity. The company makes the world's largest haul truck with the carrying capacity of 450 tonnes.
