SP Series Pneumatic Fail-Safe Brakes

Precision and Performance for Industrial Applications

The SP Series Pneumatic Fail-Safe Brake is a dependable braking system engineered for industrial environments where safety and performance are critical. Utilizing a spring-actuated, pneumatically released mechanism, the SP Series is compatible with 15mm and 30mm disc thicknesses. It features a compact structure, high braking torque, and straightforward installation. Applications span multiple sectors, including cranes, metallurgy, mining, port equipment, construction machinery, cableways, lifting systems, wind turbines, and textile production lines.

Key Features

• High Braking Torque: The SP Series provides braking torque from 1650 N·m (5SP) to 10170 N·m (3SP), offering controlled deceleration for high-inertia equipment.
• Automatic Wear Compensation: Built-in compensation mechanisms ensure stable torque delivery, minimize downtime, and extend component lifespan.
• Fast Response Time: Designed for dynamic and emergency braking, response times range from 0.15 to 0.2 seconds depending on model configuration.
• Flexible Installation Tolerances: Allows for disc face run-out up to ±0.2mm and vertical misalignment of the base relative to the disc up to ±0.4‰, simplifying integration.
• Environment-Ready Variants: Corrosion-resistant versions are available for use in outdoor or chemically aggressive environments.

Technical Specifications

• Operating Conditions: Temperature range: −20°C to +50°C. Ambient air must be non-explosive and free from flammable gases. Relative humidity ≤ 90%.
• Altitude Compliance: Designed according to GB755-2000 altitude standards for industrial equipment.
• Operating Pressure: Requires 5 bar pneumatic pressure for release operation.
• Response Time: Between 0.15 and 0.2 seconds depending on model and system configuration.
• Dimensional Data:
  • 5SP: Disc ΦB 315 mm; Weight: 34 kg; Dimensions (A: 220 mm, C: 165 mm, D: 119 mm)
  • 450SP: Disc ΦB 380 mm; Weight: 34 kg; Dimensions (A: 450 mm, C: 165 mm, D: 119 mm)
