LM 20-40-50 Locking Devices

LM 20-40-50 Locking Devices

Locking Force:
Up to 500 kN

Models within LM series (locking devices) are fail safe  and used to mechanically lock a rotational or linear application in a controlled position. The locking devices, which come in manual, hydraulic or electric versions, have a specially designed tapered pawl that is inserted into a machined slot on the brake disc or shaft flange and are equipped with proximity switches for on/off detection.

  • Specially design tapered pawls which allow engagement and disengagement even with residual forces present
  • Massive locking forces which are greater than holding brake
  • Robust and easy maintained design with long life cycle
  • Electric Operation ( 5 Sizes)
  • Hydraulic Operation (5 Sizes)
  • Manual Operation ( 5 Sizes)
  • Dual switch set up (redundancy)
  • Corrosion protection; surface paint layer thickness and shades and, stainless steel components

With a single acting (SA) brake, braking force is generated in one half of the brake and the other half slides towards it using a robust, low friction system, enabling self-alignment and making it ideal for small spaces and applications with axial movement.

The SKP model disc brake is a spring applied, hydraulically released brake which offers a reliable and safe of method of braking linear or rotary motion.

The STL Systems are "multi-function" units, all contained within one interface. It is indeed a modular system that you can choose the function(s) needed. All from single, S (Stopping) T (Turning) or L (Locking) functions.

The Twin Safe is our larger torque twin disc variation of our classic reliable SFB series, used successfully on winch motors in ship building and as a safety, service or holding brake in wharf crane installations.

A retrofitable, compact electronic status indication system to be integrated into the brake as an additional device.

Hydraulic active rotor brake

A hydraulic active rotor brake with a braking force of 44 kN that’s been specially developed for use in damp, dusty and corrosive working environments

Due to its high capacity, our SFRA brake is mainly used as a rotor brake in wind turbines. It is particularly suitable for applications with a high duty cycle.
