R+W couplings stand for uncompromising reliability, even in the most extreme conditions. This is proven by our components, systems and solutions in the mining and tunnelling industry.
Our couplings are used, for example, at the world’s largest copper mine. They prove themselves daily in an inhospitable environment, 4,300 meters long, 3,000 meters wide and 850 meters deep. Several thousand tons of copper ore are extracted every day with huge and complex bucket wheel excavators. In order to prevent extremely costly downtime in the event of an overload, mechanical safety couplings from R+W are used to limit the forces which can be applied to both the main and auxiliary drive lines.
