ROBA®-diskstop®: Safety brake system for brake discs

ROBA®-diskstop®: Safety brake system for brake discs

  • Simple assembly
  • Low maintenance
  • Insulation class F
  • Safe due to fail-safe principle
  • For high braking torques
  • ROBA®-diskstop® safety brakes are designed as a protective device against overspeed of the ascending car and against uncontrolled movements when the lift door is open.
  • The ROBA®-diskstop® is suitable for large braking torques.

Limits of use

  • direct sunlight or UV light


The ROBA®-diskstop® brake is an electromagnetic safety brake actuated by quiescent current.

In the de-energised state, springs press the armature disk against the brake disk. The brake disc is held between the lining carriers.

When a voltage is applied, the magnetic force of the coil in the coil carrier pulls the armature disk against the coil carrier against the spring pressure. The brake is released and the brake disc can pass through.
