storm brakes
SIBRE storm brakes hold rail-mounted cranes securely in place against wind and uncontrolled movement.
The range covers rail and wheel brakes, each built on a different mechanism to suit various holding forces and mounting requirements.
RPS - Rail brake
Spring force for maximum control.
The RPS combines proven SHI technology to provide reliable static braking for rail mounted cranes.
- Spring applied, hydraulically released rail brake based on the SHI-caliper design
- Presses down onto the top of the railhead to hold the crane stationary
- Runs off a shared hydraulic power pack (up to 4 brakes per pack)
- Holding force from 100 kN to 400 kN
Holding force 100 kN / 160 kN
Holding force 225 kN
Holding force 275 kN
Holding force 400 kN
RTCB - Rail brake
The RTCB uses the crane’s own weight to block reliably in an emergency.
Electro-hydraulically released, it offers a robust solution for rail-mounted crane systems.
- Gravity applied, electro-hydraulic thruster released wheel chock brake
- Bi-directionally acting, static storm brake for gantry travel
- Self-contained — no shared hydraulic power pack required
- Holding force from 225 kN to 700 kN
RHI - Wheel Brake
The RHI combines a spring-loaded design with hydraulic release. Ideal for applications that require maximum precision and reliability.
- Acts directly on the crane’s travel wheel — spring applied, hydraulically released.
- Capable of dynamic braking in emergency conditions
- Holding force from 29 kN to 125 kN (μ = 0.35) across the range
Lever arm caliper, braking force 30 kN to 125 kN (μ = 0.35)
Direct acting caliper, braking force 20 kN to 58 kN (μ = 0.35)
RB - Rail Clamp
Security that clings on.
The RB rail clamp from SIBRE ensures maximum safety for rail-mounted crane systems. Thanks to a braking mechanism that inherently compensates for lining wear, it offers reliable protection in extreme weather conditions.
- Spring applied, electro-hydraulic released (via integrated HPU)
- Grips both sides of the rail head to hold cranes stationary in high winds or power loss
- Continuously guided on the rail by flange wheels, accommodating vertical and horizontal rail fluctuation
- Holding force from 200 kN to 1000 kN (μ = 0.5) across the range
Spring-applied, holding force 200 kN to 1,000 kN (μ = 0.5)
