1500 kN (higher force on request)

These rail clamps are storm brakes suitable for high forces. They are self-blocking type; in case a force acts on the crane and tends to put the same into motion, they press on the rail sideways. This pressing gets stronger as the crane moves. The rail clamps can withstand horizontal force only.

  • Holding force = up to 1500 kN
  • Vertical float = ± 12 mm (to be checked upon rail type)
  • Horizontal float = ± 40 mm
  • Rail tolerance = ± 1,5 mm
  • Opening time = 4 seconds
  • Adjustable closing time (5 ÷ 18 s)
  • Easy maintenance
  • Emergency manual opening device
  • Hand Pump
  • Working temperature different from standard (-20°, +40°)
  • Double side flanges or upper flange (with hydraulic unit supplied separately from rail clamps)
  • Hydraulic unit suitable to operate with more than one rail clamps
  • Electrical board (on plate or box IP55)
  • Limit switch which signals „rail clamps closed”
  • Horizontal and vertical clearance increased
  • Security side stowage pins
  • Manufacturing according Q.C.P. different from our standard
  • Language of documentation different from standard
  • Certificates of materials (EN 10204-2.2, EN 10204-3.1 o EN 10204-3.2) for all main components

Additional PRODUCTS

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.

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 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.
