Reliability under the most extreme conditions

Thousands of tons of copper matte is removed daily from the world's largest copper mine, which is 4,300 meters long, 3,000 meters wide and 850 meters deep . Huge bucket wheel excavators are used for this operation. To avoid very costly excavator downtimes, mechanical safety couplings by R+W are used to limit the force in the main and auxiliary drives.
