Crane safety brakes

Hydraulic Safety Emergency Brakes

The SB series crane safety brakes are high-power braking devices designed for low-speed shafts (drum shafts). These brakes are widely suitable for emergency safety braking on medium and large cranes, port handling machinery lifts, and boom tilting mechanism low-speed shafts. They are also ideal for the operational and emergency safety braking of mining hoists, lift equipment, and high-power inclined belt conveyors, as well as for safety braking in cable car and cable crane drive mechanisms. Additionally, they provide emergency braking for the low-speed shafts of hoist mechanisms in special lifting applications, such as casting cranes.

Main Features of Crane Safety Brakes

• Featuring a normally closed design, these brakes are safe and reliable. The braking force is applied by a specially designed disc spring, while hydraulic power releases the brake (see the hydraulic station catalog for hydraulic station selection).
• Equipped with high-performance, asbestos-free hard friction pads, they offer a stable friction coefficient without damaging the brake disc and are resistant to water and salt fog (sea spray).
• The brakes are highly responsive, with short closing (braking) times.
• Optional switches, such as release limit and pad wear limit, are available for signal display or interlock protection.
• A well-designed sealing structure and premium imported seals provide effective sealing and long service life.
• Flexible installation options make the brakes easy to use, adjust, and maintain.

Operating Conditions for Crane Safety Brakes

• Ambient temperature: -20°C to +50°C
• Relative humidity: ≤90%
