Product IntroductionThe disc brake is a key executive component of the hoist braking system. Together with the hydraulic power unit and piping system, it forms a complete braking system for the hoist’s service braking and safety braking. It generates braking force via disc springs and releases the brake using hydraulic pressure, with braking force acting along the axial direction.
Application Scope:
The disc brake is a high-performance, high-reliability braking device and a key safety component for various heavy-duty hoisting and conveying equipment.
Integrating advanced electromechanical-hydraulic control technology and precision structural design, it provides safe, accurate, and efficient braking solutions for mining hoists, port cranes, construction winches, and heavy-duty material handling systems.
| Structure Features & Working Principle: |
This product adopts a rear-mounted cylinder with dual-circuit hydraulic structure, integrating disc spring stored energy braking force and hydraulic system energy release control functions. During operation, the hydraulic station provides oil pressure to drive the piston and compress the disc springs to release the brake. When the hydraulic pressure is released, spring force acts evenly on both sides of the brake disc through the brake shoes, forming a reliable braking torque. The system supports single or multiple units in combination to effectively balance axial forces and meet different load levels and dynamic braking requirements. |
| Structure Features: ○Uses high-performance ferrule-type hydraulic fittings with an IP67 sealing rating to prevent leakage and contamination. ○The piston rod surface undergoes QPQ salt bath composite treatment for excellent wear and corrosion resistance. ○Integrated spring-hydraulic composite drive mechanism with fast response and precise torque adjustment capabilities. ○Modular component design supports quick disassembly, assembly, and maintenance, significantly reducing equipment downtime |
| Performance Features: ○Low moment of inertia design with a response time ≤ 0.3s, enabling millisecond-level braking intervention. ○The braking torque is linearly and infinitely adjustable with a control accuracy of ±2%. ○Compact design compatible with various industry-standard interfaces and mounting configurations, supporting long-term stable operation under continuous heavy-duty conditions with a mean time between failures ≥ 10,000 hours. ○Equipped with overheat protection and automatic wear compensation functions to significantly improve system safety margin. |
The disc brake can be seamlessly integrated with intelligent hydraulic stations, PLC control systems, and safety monitoring modules to form a complete braking solution. The system supports remote monitoring, fault diagnosis, and predictive maintenance, enabling real-time data interaction with the hoist's main control system to ensure precise synchronization between the braking process and equipment operation status. As the core unit of modern industrial braking systems, the disc brake provides reliable safety assurance for mining, port operations, construction, and heavy industry through its outstanding reliability, precise control performance, and strong environmental adaptability. |

Customer SiteThe disc brake is a key actuator in the hoist braking system, forming a complete braking system together with the hydraulic station and pipeline system. It is used for both working braking and safety braking of the hoist.
The disc brake generates braking force through disc springs and releases the brake using hydraulic pressure, with the braking force acting axially. The magnitude of braking force, maintenance, and adjustment significantly affect the safe operation of the entire hoist system. Installation and operating units must pay close attention to ensure operational safety.
Performance Features:
Braking torque is highly adjustable.
Low inertia, fast action, and high sensitivity.
High reliability: multiple brakes (typically 2–12) can work simultaneously. If one fails, only a small portion of braking force is lost, and the hoist can generally still be stopped. In case of hydraulic station or system failure, braking is automatically applied.
Good versatility: many parts are interchangeable, and the same model of disc brakes can be used on different hoists in varying quantities. Simple structure, easy maintenance, and adjustment.
1. The piston and brake shoes of the disc brake should operate simultaneously under the design hydraulic pressure, without crawling or sticking.
2. Under no-load conditions, the minimum operating pressure of the disc brake piston should not exceed 0.3 MPa.
3. Under the design hydraulic pressure, the stroke of the disc brake shoes should not differ from the design stroke by more than 10%.
4. When maintained at 1.25 times the design pressure for 10 minutes, no oil leakage should appear at any seal.
5. The disc brake should be equipped with a brake shoe over-wear protection device and a spring fatigue warning device.
6. The disc brake should be fitted with an air release device.
To meet the requirements of various series of mine hoists, disc brakes are available in different specifications.
