One system:  stop, block, turn / SBT-systems

For ship propulsion up to 25 MW per propeller shaft

STOP-BLOCK-TURN System system is made up of one or several disk brakes, locking elements and turn devices.

Our SBT devices (Stopping - Blocking - Turning) are mainly used on propeller shafts in marine applications: ranging from small yachts to cruise ships or large supply vessels.

The functions "stop", "block" and "turn" can optionally be implemented individually or as a double or triple version:


»stop«, »block« or »turn«


»stop and block«, »stop and turn« or »block and turn«


»stop, block and turn«

All versions are supplied along with a control allowing for local triggering of the device from the engine room or from the navigation bridge. The SBT device is available as an electrical or hydraulic version. State-of-the-art electrical ship drives can additionally be equipped with the "all electric" version which is very quiet.


  • redundant safety limit switch

  • easy replacement of brake pads

  • all common supply voltages of drives possible

  • Control with local operation and interface to the bridge

  • mechanical and manual operation possible
