💡 Key Features & Characteristics
Fail-Safe "Normally Closed" Design:
Spring-Applied, Hydraulically Released: The braking force is generated by a powerful set of碟形弹簧 (disc springs). To release the brake, a hydraulic power unit supplies pressure. This ensures that in the event of a power outage or hydraulic system failure, the brake automatically and instantly engages to secure the equipment.
Emergency Braking: Designed specifically for emergency stops and as a safety barrier to prevent load drops or uncontrolled equipment movement.
High-Performance Specifications:
Massive Clamping Force: Delivers a nominal clamping force of 250 kN, making it suitable for heavy-duty applications requiring immense braking torque.
Fast Response Time: Features a highly sensitive mechanism with a short closing (braking) time, ensuring rapid stops during critical situations.
Robust & Durable Construction:
Friction Pads: Utilizes high-performance, non-asbestos hard friction linings. These pads provide a stable friction coefficient, do not damage the brake disc, and are highly resistant to water, salt spray (ideal for port/marine environments), and high temperatures.
Automatic Compensation: Equipped with an automatic wear compensation device. As the friction pads wear down over time, the mechanism automatically adjusts to maintain a constant braking torque and optimal air gap.
Excellent Sealing: Features a rational sealing structure with high-quality imported seals, ensuring long service life and preventing hydraulic oil leaks.
Smart Monitoring & Easy Maintenance:
Limit Switches: Can be optionally equipped with limit switches for "brake open" status and "pad wear limit". These provide interlock protection and fault signals to the system's PLC, enhancing overall operational safety.
Flexible Installation: Designed with large installation tolerances, making it easy to install, adjust, and maintain in complex industrial environments.
🏭 Typical Applications
The SBD250-C is essential for safety-critical machinery in heavy industries:
Port & Harbor: Emergency braking for ship-to-shore cranes, RMGs, and bulk material handling machinery.
Mining: Safety and service braking for mine hoists, winches, and large inclined belt conveyors.
Metallurgy & Construction: Emergency braking for heavy-duty casting cranes, tower cranes, and other lifting mechanisms.
Cable &索道 (Ropeways): Drive mechanism safety braking for cable cars, passenger ropeways, and索道 cranes.
Wind Power & General Industry: Braking systems for wind turbine drives, textile machinery, and other heavy mechanical drives.

Note: The SBD250-C is a critical safety component. It requires a dedicated hydraulic power unit (hydraulic station) to function, which must be selected and matched according to the manufacturer's specifications. Due to its massive 250 kN clamping force, always ensure that the machine's shaft, brake disc, and mounting foundation are structurally capable of withstanding the immense reaction forces generated during emergency braking.
