Swedish steelworkers awarded the world’s largest dump truck with a Swedish Steel Prize

27 November 2014
The BelAZ-7571 dump truck with a record-setting load capacity of 450 ton got a prestigious Swedish Steel Prize, which is aimed at support of projects for the creation of light, safe and environmentally friendly production of high-strength steel.

“BelAZ crossed the boundaries of what was previously thought as possible with use of available technology,” – says Martin Lindqvist, head of SSAB company, that had established the award.

The dump truck really deserves the prize: it is impossible to create a world’s largest dump truck by just scaling the existing models. With increase of linear dimensions of the structure, its mass increases by cubic law, so in pursuit of record-breaking load capacity the designers had to look for new solutions. That’s why the new dump truck is made of high strength Swedish steel WELDOX 700F, which provides the necessary strength, high toughness at subzero temperatures, suspension mount kinematics and low steel intensity.

But the steel is not the only innovative solution, used for construction of the dump truck: in 2011 BelAZ had turned to Siemens plant in search of the new electric transmission for a future vehicle. Its task was to reduce the costs of transportation of ton of cargo and make the unloaded dump truck move at a maximum speed of 64 km/h. Siemens, that had been making transmissions for dump trucks for 15 years, got the job started.

To provide the stated load capacity, the dump truck was decided to equip with eight wheels instead of six, 100 tons per wheel. It was also decided to use the 4-wheel drive, based on four power wheels, that are powered by two 1700 kW MTU DD 16V4000 engines.

The dump truck is also equipped with VIST Group’s Payload Control System, as well as other BelAZ trucks, that is making the dump truck operation even more effective.

The first giant dump truck was developed of request and now operates in Chernigovets open pit mine in Kemerovo region (Russia) as a part of mining fleet management system
KARIER, which is already used by mining enterprise.
