Below ground, conditions are extreme. In the transportation of people and materials by mine rail, water and the mineral salts dissolved in it place the highest demands on our products. Thanks to their excellent material properties, we only use wheels from our high-performance VULKOLLAN® 95 Shore A range for this purpose. The material can stand the test of the strongest loads and has a high static friction value, enabling it to handle inclines and declines of up to 30 degrees. The long service life has already been testified by our customers on many occasions.
