ROBA®-duplostop®: Doubled safety brakes for elevator machines

  • Reliable due to fail-safe principle
  • Easy installation
  • Preset air gap
  • Noise-damped
  • Class of insulation F

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


The ROBA®-duplostop® brake is a spring-applied, electromagnetic safety brake.

In de-energized condition, springs press against the armature disks. The rotor is therefore held between the armature disks and the relevant screw-on surface of the machine. The motor shaft is braked via the rotor.  

When the power is switched on, a magnetic field is built up. The armature disks are attracted against the spring pressure to the coil carrier. The rotor is released, and the shaft is able to rotate freely.
