STATIC RAIL BRAKE – CLASSIC
Rail Brakes directly apply disc spring force on the top of the rail head. They utilize the weight of a crane in the braking process and provide the braking force along the rail. Once released, the brake hangs above the rail at a pre-designed clearance. Actual braking capacity depends on the applied force calculated with 0.5 coefficient of friction for static braking with serrated shoe.
BENEFITS
Brelx design with disc springs allows for large variations of the rail height by means of a longer spring stroke, still achieving balanced braking force / stroke curve. It provides consistently greater braking / holding force at increased shoe to rail clearances. Unique design and spring selection allows unrestricted spring movement for greater rail height fluctuation still ensuring long spring life.
KEY FEATURES
Rail Brake Mechanism: Spring set – Hydraulic release
- Largest installation clearance (@16mm air gap) in the industry
- Oversized longer lasting springs for reduced maintenance
- Flow control valve installed on the brake for controlled setting time
- IFM Proximity switch for release indication
- Serrated shoe easily removed and replaced
- Brakes are fabricated from high quality structural steel
- Small number of moving parts means that maintenance can be done with Eliminates
- Emergency release Spacers
- Installation bolts can be used as Emergency Release Bolts
- Manual release (hand pump installed on the Hydraulic Power Unit)

DYNAMIC RAIL BRAKE – CLASSIC
Rail Clamps are static Storm Brakes which clamp onto both sides of a crane rail head, this provides the friction force necessary to prevent the crane from moving along it’s rails in case of sudden wind bursts. They are activated on loss of electrical power and are spring set. Can be hydraulically OR electrically released.
STATIC RAIL BRAKE – SELF ADJUSTING
Thruster Service Brakes are mainly used on high speed driveshafts. They apply on the shaft disc to stop rotational motion. They are spring set and hydraulically OR electrically released.
