UCM fix
Ideal for modernization
and retrofitting

The UCM-Fix is an emergency braking system that prevents both uncontrolled upward movements and uncontrolled car movement when the car doors are open

= can be used for UCM SAfü.

The system makes use of a spring-loaded accumulator operated by a quiescent current.
The brake is therefore forcibly actuated in the de-energized state.

The UCM-Fix is delivered completely ready for installation with the following parts:

  • Brake magnets with brake pads.
  • Mounting bracket (designed and manufactured specifically for the system).
  • Optional: Terminal box with overexcitation to control the magnets.


The following parts are only required for early opening doors and the readjustment function:

  • Magnetic tapes with fastening set.
  • Control unit EN81 A3 with switching power supply 24V.


Further available options if required:

  • Speed limiter double-acting with EN81-20 / 50 certificate.
  • Complete mechanical assembly on site.


Advantages of UCM-Fix compared to other systems:

  • Easy to assemble.
  • The mounting adapter is calculated and designed specifically for the system using FEM simulation, and the corresponding drawing is made available prior to delivery. So no on-site adjustments are necessary!
  • Lowest noise development.
  • Almost maintenance free.


Available performance sizes:

  • UCM-Fix: 600 - 5500 Nm braking force corresponds to 1: 1 systems up to Q approx. 630kg - 3500kg
