Above ground or underground, in Europe or worldwide - raw materials are mined everywhere. Whereas in the past mining was mainly about extracting coal for energy, today other important substances also play an increasing role. But no matter how much the image of mining may have changed, not least due to the increasing replacement of hewers and risers by modern instruments, two themes remain present: energy and safety. They play the main roles against a backdrop characterised by its harsh conditions with strong vibrations and large temperature fluctuations. The (partial) electrification of drives can make an essential contribution to improving efficiency and working conditions.
 

Electric drive technology is used both in shearer loaders and road headers, which operate directly underground, and in conveyor systems such as monorail overhead conveyors, which ensure that tools, material and people are transported to and from the site. They therefore enjoy advantages along the entire process chain. With precise control, overburden machines equipped with REFUdrive components can be used for mining not only in large seams but also in low seams of 0.6 m and benefit from energy recovery, among other things. In addition, REFUdrive enables the use of monorail hanging railways through the special control of the entire system. REFUdrive thus offers your industry optimal solutions for the further way into the future.
