Products

Bottom Dumper NO-RG Fanoo

In May 2013, Kiruna Wagon received an order to manufacture 40 ore wagons for Norwegian mining company no:Rana Gruber AS. The NO-RG Fanoo Bottom Dumper, which is built for a 30-tonne axle load, empties its load through a large bottom door. The wagon is a further development and refinement of the Bottom Dumper built for LKAB and designed to deliver low tare weight and high payload advantage and enable a more environmentally friendly transportation. The NO-RG Fanoo Bottom Dumper is used by Rana Gruber to transport primary sized crude ore, 0-300 mm in size and with a high quartz content, from the Kvannevann underground iron ore mine and satellite open pit deposits in the Ørtfjell area to the dressing plant and port in Mo i Rana.

Helix Dumper FAMMRR¹²¹

In April 2012, Kiruna Wagon entered into agreement with international mining company Northland Resources S.A. to produce 150 iron ore wagons for the transport of ore concentrate from Northland’s transhipment terminal in Pitkäjärvi in Sweden, to the ice-free port of Narvik in Norway. Constructed mainly of high-strength steels, with yield strength of 700 MPa, the FAMMRR¹²¹ Helix Dumper has a low tare weight to maximise payload and is designed with an innovative body-turning device for efficient, continuous discharge of even the toughest concentrate materials.

Underground wagons for LKAB

In December 2010, Kiruna Wagon was contracted to manufacture 121 underground wagons for the transport of crude ore at LKAB’s new main level, 1,365 metres below ground. The drawings were provided by the customer, LKAB. The heavy-duty wagons are loaded through the ore-pass chute and emptied through effective bottom discharge, whereby the entire bottom of the wagon is opened in a discharge curve. The wagons have an unloading capacity of approx. 10,000 tonnes/h.

Side Dumper TAIMN⁰⁹¹

Since 2009, Kiruna Wagon has manufactured Side Dumpers for the Swedish mining and smelting company Boliden AB. The Side Dumper TAIMN⁰⁹¹ for Boliden is a closed container wagon designed for the transport of ore concentrate in an environmentally sustainable way. The 4-axle bogie wagon measures a little over twelve metres and has a capacity of carrying 73 metric tonnes, or 40.5 m³. The wagon is equipped with a roof for environmental reasons and is constructed for both left and right-side tipping. The subarctic climate influences the choice of materials and the wagon is made mainly of advanced high-strength steels.

Bottom Dumper FAMMOORR⁰⁵⁰

Kiruna Wagon’s largest order to date is the manufacture of Bottom Dumper FAMMOORR⁰⁵⁰ for Swedish mining company LKAB which commenced in 2005. The order constitutes Sweden’s largest wagon project to date, with a total order value of SEK 1,500 million. When in operation, the ore wagons travel in pairs – two short-coupled Fanoo⁰⁴⁰ making up one Fammoorr⁰⁵⁰. The new-generation ore wagon is built for a 30-tonne axle load and carries up to 100 tonnes, which is 25 per cent more than the previous generation wagons. The wagons are manufactured in collaboration with K Industrier in Malmö, which builds the chassis while Kiruna Wagon is responsible for the manufacture of the body and hatch system and for final assembly. In September 2012, Kiruna Wagon delivered the 1000th wagon to LKAB.

Bottom Dumper Uadk

In 2003, K Industrier in Malmö, with Kiruna Wagon as subcontractor, was awarded the contract to produce 110 ore wagons of the Uadk type for LKAB. The Uadk wagon is a modification of LKAB’s earlier Uad wagon, built for a 25-tonne axle load and with a capacity of transporting 80 tonnes.
