Hydraulic Disc Brake
Description:
A winch hydraulic disc brake is a type of powerful braking system used in heavy-duty winches, especially in cranes, hoists, marine equipment, and mining machinery. It ensures controlled stopping and holding of the load, even in demanding environments.
It can be a model SBD-A clamp brake system, a mode SB(YQP) disc brake system and a model YPZ disc brake system.
SBD-A Hydraulic Safety (Emergency) Brake:
The SBD hydraulic safety brake is a high-power braking device designed for use on low-speed shafts. It is widely applied as an emergency safety brake in large and medium-sized cranes, port loading and unloading equipment, and the lifting and boom luffing mechanisms of such machinery. Additionally, it serves as both a working brake and an emergency safety brake for mine hoists, heavy-duty lifting systems, and high-power inclined belt conveyors.
SBD-A Features:
-
Normally closed design ensures safety and reliability.
-
Quick and responsive braking with flexible operation and short braking time.
-
Equipped with limit switches for brake opening and brake lining wear detection.
-
Uses non-asbestos brake linings with a stable friction coefficient, ensuring no damage to the brake disc.
-
Features a well-engineered structure with high-quality imported seals for durability.
-
Easy to install, operate, and adjust, ensuring user-friendly maintenance.

SB(YQP) Hydraulic Disc Brake System:
The SB(YQP) hydraulic disc brake system is a high-performance, normally closed braking solution designed for critical applications requiring reliable stopping and holding power. Engineered for use on low-speed shafts, it is ideally suited for cranes, port handling equipment, mine hoists, and heavy-duty belt conveyors.
SB(YQP) Features:
-
Normally Closed Design
The brake remains in a braking state when unpowered, ensuring fail-safe operation and high reliability. -
Disc Spring Force Braking
Utilizes special disc springs to provide quick, sensitive braking action with minimal response time and strong braking force. -
Hydraulic Release Mechanism
Braking is released via hydraulic actuation, enabling simple operation and fast response. -
Optimized Sealing Structure
Designed with a reliable sealing system for effective performance, extended service life, and stable long-term operation. -
Flexible Installation and Maintenance
Allows versatile mounting positions. Easy to install, adjust, and maintain, reducing operational complexity. -
Interlocking Protection and Fault Indication
Equipped with a limit switch for brake opening and a wear detection switch for brake linings. These features provide interlock protection and real-time fault display, enhancing operational safety.

-
High Efficiency: Equipped with self-lubricating bearings at the main swing hinge, ensuring high transmission efficiency and maintenance-free operation.
-
Spring Mechanism: Brake spring housed within a spring tube and torque rod, with a visible torque indicator for easy torque adjustment.
-
Brake Pads: Uses asbestos-free, card-insert type brake pads—safe, reliable, and quick to replace.
-
Self-Balancing Pad Clearance: Interlocking back clearance mechanism keeps brake pad distances equal on both sides, preventing uneven wear or improper contact with the brake wheel.
-
Brake Timing Control: Brake opening and closing can be delayed via the rise/fall valve in the actuator device.
-
Optional Features: Can be equipped with various brake accessories to enhance functionality.
-
Automatic Compensation: Wear of brake linings is automatically compensated, ensuring consistent brake pad clearance and torque.
-
Position Display Switch: Indicates whether the brake is open or closed and provides interlock protection signals.
-
Wear Limit Switch: Alerts when brake pad wear reaches the limit and can trigger interlock protection.
-
Manual Release Device: Allows manual brake release when the system is inactive, facilitating maintenance and inspection.
Working Environment:
-
Ambient Temperature: -20°C to +50°C.
-
Relative Humidity: ≤ 90%.
-
Altitude: Installation site must comply with GB755-2008 altitude requirements.
-
Operating Environment: Must be free of flammable, explosive, or corrosive gases. For hazardous environments, explosion-proof or anti-corrosion models should be used.
-
