ABB taps a rich seam

ABB announced today that it has won a $20m contract from mining and minerals group LKAB to raise productivity at an iron-ore mine in Kiruna, Sweden.



ABB will supply hoists, used to haul ore to the surface, as well as hoist-control systems and drives to help increase production at Kiruna by 25 percent and support extending the depth of the mine by about a third to 1,365 metres below the surface.



ABB will supply ACS6000SD variable speed drives, 5600kW synchronous machines and AC800M control systems to four existing underground hoists.



In addition, ABB will provide a new turnkey mine hoist with complete mechanics and brake system at surface level. The modernisation will begin early next year and continue through 2008.



ABB says it had record sales of hoist systems in 2005 as mining companies invested in raising output to meet a surge in global demand for commodities.
