RPS-SA Rail Brakes Self Adjusting | Stromag

RPS-SA Rail Brakes compensate an extra large ±19mm rail vertical fluctuation, they are automatocally adjusted before braking

RPS-SA brakes apply spring force on the top of the rail, they use the weight of the crane in the braking process and provide the friction force along the rail. Two step braking ensures that the shoe is in contact with the rail before spring force is applied.

They are spring set and hydraulically or electrically released. Once released, the brake hangs above the rail at a pre-designed clearance. Actual braking capacity depends on the applied force and applicable coefficient of friction (different for static and dynamic braking).

Product Features

  • Completely spring-set rail brake
  • Allows up to 38mm rail vertical fluctuation while providing uniform rated capacity over the full range of movement
  • Consistent spring stroke for longer spring life
  • Serrated / Smooth shoes fully protected from hitting the top of the rail for less wear and tear
  • All components, including the hydraulic release cylinder are fully enclosed in a sealed housing, out of the elements
  • Flow control valve installed on the brake for controlled setting time
  • Proximity switch for release indication signal
  • Brake shoes easily removed and replaced
  • Made with high quality structural steel
  • Compact design fits most existing locations, even those with drop pins. Low height allows retrofitting with adapter flanges.
