Emergency disc brake series DBF
Disc brakes of type DBF series are spring-applied and hydraulic-released safety brakes (emergency brakes) and operate on the "failsave" principle, i.e., the brake closes when the valve voltage is disconnected at the power unit or a power failure occurs.
The application is preferably at the washer disc of rope drums in hoisting- and boom hoisting gears and they are also applicable in belt conveyors or other conveying systems.
The brake consists of two identical halves which are mounted to a bracket. On request, we supply brake and bracket with attached hydraulic unit – oil filled, bled and electrically wired – as an assembled unit.
Note: These brakes are only conditionally suitable as stopping brakes. Brake lining wear must to be adjusted manually.
