ROBA®-duplostop®: Safety brake in a double pack for elevator drives

  • Safe due to fail-safe principle
  • Simple assembly
  • Preset air gap
  • Silenced
  • Insulation class F

The ROBA®-duplostop® is a redundant safety brake for elevator drives.


The ROBA®-duplostop® brake is a quiescent current actuated, electromagnetic safety brake.

In the de-energised state, springs press against the armature disks. The rotor is thus held between the armature disks and the respective screw mounting surface of the machine. The motor shaft is braked via the rotor.  

When the current is switched on, a magnetic field builds up. The armature disks are pulled against the spring pressure to the coil carrier. The rotor is free and the shaft can pass freely.
