The STL Systems are "multi-function" units, all contained within one interface. It is indeed a modular system that you can choose the function(s) needed. All from single, S (Stopping) T (Turning) or L (Locking) functions.

The Twin Safe is our larger torque twin disc variation of our classic reliable SFB series, used successfully on winch motors in ship building and as a safety, service or holding brake in wharf crane installations.

A retrofitable, compact electronic status indication system to be integrated into the brake as an additional device.

Hydraulic active rotor brake

A hydraulic active rotor brake with a braking force of 44 kN that’s been specially developed for use in damp, dusty and corrosive working environments

Due to its high capacity, our SFRA brake is mainly used as a rotor brake in wind turbines. It is particularly suitable for applications with a high duty cycle.
