Whether by surface or underground mining, generally millions of tons of material must be moved in order to extract targeted raw materials or minerals. Indeed, it is not uncommon that mountains are literally moved in mining operations. The often gigantic tunnel boring and cleaning machines, conveyor systems, bucket wheel excavators, special vehicles, material grading and separating systems, etc are often in service 24 hours/day, for years. PINTSCH BUBENZER has been meeting the special challenges set by the specialty manufacturers of these machines, systems and vehicles for many years and today is rated world-wide one of the leading development partners and system suppliers. In close co-operation with the manufacturers of mining equipment, PINTSCH BUBENZER Engineering is always providing solutions to operational and safety braking challenges.
