Sweden: unloading minerals at high speed
This year’s winner of the international Swedish Steel Prize is Kiruna Wagon from Sweden. The award was presented for the Helix Dumper, Kiruna's innovative wagon solution.
Kiruna Wagon used high-strength steel to develop a highly durable and far more efficient wagon solution than other ore wagons on the market. Kiruna dumper wagon systems are designed for long distance rail transport and efficient unloading of minerals.
The lightweight wagons are combined with a stationary Helix terminal for on-the-fly rotary unloading. The ingenious solution has an unloading speed of 25,000 t per hour, which is twice that of other systems. (ben)
