LKAB is set to add to its electric fleet at the Malmberget mine in northern Sweden after agreeing to acquire a LF-19EB tethered-battery electric loader from Germany-based GHH.
The manufacturer welcomed a team of LKAB team experts to its factory and testing ground in Gelsenkirchen, Germany, this month, with a successful Factory Acceptance Test of the LF-19EB taking place.
The LF-19EB is a 19-t-payload LHD initially designed for feeder breaker loading in the soft rock, salt and potash mining industries. It has a 34 kWh on-board battery for panel-to-panel electric tramming, with a tractive effort force of 380 kN and an average of 250 kVA under permanent load and 315 kVA peak. It has a maximum cable length of 310 m, which provides loading flexibility when plugged into the mine grid.
The loader heading to Malmberget has been upgraded for hard-rock applications with input from the customer, GHH says.
LKAB has tested and used several pieces of battery-electric equipment from different vendors at its Malmberget mine, while its Kiruna mine was among the industry’s earliest adopters of cable-electric loading, trialling its first Sandvik unit in 1985.
