SBD365-C Safety Brake

 

 

💡 Key Features & Characteristics

Fail-Safe Operation (Spring-Applied, Hydraulically Released):

Normally Closed Design: The brake operates on a "power-to-release, spring-to-brake" principle. High-performance disc springs apply the braking force, while a hydraulic station provides the pressure to release it.

Automatic Emergency Braking: In the event of a sudden power loss or hydraulic system failure, the stored energy in the springs instantly clamps the brake pads onto the disc, ensuring a safe and rapid stop.

High-Performance Specifications (SBD365-C):

Rated Clamping Force: Delivers a massive 365 kN of clamping force to generate the required braking torque.

Braking Torque Formula: The braking torque ( MM ) is calculated as: M=μ×d1×FM=μ×d1​×F , where μμ is the friction coefficient (typically 0.35), d1d1​ is the friction diameter of the disc ( D−220D−220 mm), and FF is the total clamping force in kN.

Brake Disc Compatibility: Designed to operate with large brake discs, typically requiring a disc diameter ( DD ) of ≥≥ 1800 mm.

Rapid Response: Features highly sensitive action with a very short braking (closing) time. For disc brake variants, the air gap closing time (idle stroke time) is typically less than 0.3 seconds.

Advanced Mechanical Design:

High-Friction Linings: Equipped with high-performance, non-asbestos hard friction linings. These provide a stable friction coefficient, do not damage the brake disc, and are highly resistant to water, salt spray (ideal for port machinery), and other environmental agents.

Smart Monitoring Options: Can be optionally equipped with limit switches to monitor the "brake released" status and "lining wear limit". These signals can be integrated into a PLC system for interlocking protection and real-time fault indication.

Durable Sealing: Features a well-designed sealing structure, often utilizing imported high-quality seals, to ensure excellent protection against dust and moisture, resulting in a long service life.

Automatic Wear Compensation: Includes mechanisms to automatically compensate for pad wear, maintaining a consistent air gap and stable braking torque over time.

Environmental Adaptability:

Designed to operate reliably in ambient temperatures ranging from -20°C to +40°C (some variants support up to +50°C) and in environments with relative humidity up to 90%.1

🏭 Typical Applications

The SBD365-C is a mission-critical safety component widely used in heavy industries:

Port & Lifting Machinery: Emergency safety braking for the hoisting and luffing mechanisms of large and medium-sized cranes, container cranes, and port handling equipment.

Mining & Hoisting: Service and emergency braking for mine winders, heavy-duty hoists, and large inclined belt conveyors.

Specialized Equipment: Safety braking for cable cars, ropeway cranes, and foundry cranes.1

Note: The SBD365-C is a vital safety device that requires a matched external hydraulic station to function. When installing, ensure the brake disc surface is free of severe rust, oil, or welding marks. Regularly inspecting the thickness of the friction linings and testing the limit switches are essential to maintain the brake's optimal safety integrity and rapid emergency response capabilities.
