Besides having steeper ends \u2013 50 degrees rather than 40 degrees \u2013 the main new feature is that the entire basket will be made of Duplex Stainless Steel. Together, these modifications will ensure complete discharge of many types of goods.<\/p>\n<p>The Duplex steel guarantees a stainless surface on the basket, and good discharge properties in the long term \u2013 also for goods that can be hard to release. Thanks to the material\u2019s high strength, the weight and thickness can be reduced, making it a cost-effective option for mining transportation. Good weldability and malleability also make it ideal as part of a construction. The material in all the outside reinforcements and bars is normal steel. Welding stainless onto \u2018black\u2019 material presents a new challenge for the workshop.<\/p>\n<p>In the bottom section or \u2018skirt\u2019 of the basket, the new Duplex steel is welded onto the reused, black steel parts. To minimise the risk of goods getting stuck, the hatches are coated with Matrox\u00ae wear plastic, which has been specially developed for bulk material handling in the mining industry and has outstanding strength in demanding applications.<\/p>\n<p>\u201cThis project is a great example of how it really is possible to renew existing wagons using modern, high-performance materials,\u201d says Pawel Karas.<\/p>\n<p>The wagons will be completed during the spring and delivered to LKAB Malmtrafik at the end of June 2018.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Kiruna Wagon, an NMV Group company, has been commissioned to refurbish 50 bottom dumpers for raw material transport between LKAB sites. \u201cThis project calls for a lot of customisation, since we\u2019re renovating and reusing undercarriages from old UADK wagons and fitting them with new baskets,\u201d says Pawel Karas, Project Manager at Kiruna Wagon.
