DELLNER BUBENZER BRAKES
SATISFACTION CONNECTS. For this reason, Dellner Bubenzer brakes oftentimes represent the best possible solution for global manufacturers. Our brake systems for excavators and conveyors are adapted to individual demands of our customers.
Furthermore, we can also developed control systems for defined braking of conveyors, explosion-proof brakes for use in caves, as well as special brake pads for specific use.

Safety brakes
KFB service brakes are primarily used for internally and externally ventilated motors on trolleys, hoist reducer, and in crane drives.
SFB brakes are successfully used on winch motors in ship constructions, and as service brakes on port cranes.
Storm brakes
The SOS system is the first anti-overload system without hydraulic parts for securing container lifts. This prevents the risk of damage to the structure when starting the engine, which is the main source of inertia in addition to the brake disk.
In case of an overload, the Malmedie Safety Clutch (MSC) instantly separates the motor and its high inertia mass from the gearbox. DELLNER BUBENZER safety brakes (SF) immediately stop the load and prevent the rope from being lost / broken. LiTec ® service brake discs further reduce inertia.
Components
- malmedie safety coupling,
- MSC DELLNER BUBENZER LiTec ® inertia brake disc with reduced torque,
- SB 28 DELLNER BUBENZER service brake SB 28,
- DELLNER BUBENZER SF safety brake with CMB force control sensors (quick execution setting),
- DELLNER BUBENZER SOS PLC,
- malmedie TTX drum coupling,
Main characteristics
- MSC relaxation time <1 mx,
- protection is performed in less than 100 ms,
- separate and independent SOS PLC,
- housing 600 x 600 x 300 mm retrofit,
- manual system reset after mandatory inspection.
