It eliminates the danger of structural damage starting at the motor, which is beside the brake disc the major source of snag inertia load. In a snag overload case the Malmedie Safety Coupling (MSC) separates the motor drives and their high mass inertia from the gearbox instantly. PINTSCH BUBENZER safety brakes (SF) immediately catch the load and avoid a loss of rope. LiTec® operating brake discs reduce the inertia additionally.
