The TWZ(B) Series Normally Open Foot-Pedal Operated Drum Brake is specifically designed for the slewing structures of various medium and small-sized portal cranes and tower cranes. This brake is equipped with a manual clutch device, enabling reliable braking when the crane is in non-operating conditions. It provides robust and safe braking solutions, ensuring stability and preventing unwanted movement in crane systems.
Product Features
- Interlocking Mechanism with Equal Retreat Distance The TWZ(B) series features a sophisticated interlocking mechanism that ensures equal retreat distances on both sides of the brake linings. This design completely eliminates the risk of uneven retreat distances, preventing one side of the brake lining from floating and potentially causing issues with brake engagement.
- Self-Lubricating Bearings at Key Pivot PointsCritical pivot points are equipped with self-lubricating bearings that ensure high transmission efficiency and a long service life. These bearings do not require lubrication during operation, which reduces maintenance needs and increases operational uptime.
- Card-Insertion Brake Linings and Blocks The brake linings and blocks are designed with a card-insertion method for secure installation. This design makes replacing the brake linings quick, easy, and safe, improving the efficiency and convenience of maintenance.
Operating Conditions:
- Ambient Temperature: -20℃ to +50℃
- Environmental Conditions: The surrounding environment should not contain flammable, explosive, or corrosive gases. The relative humidity should not exceed 90%.
- Outdoor Use: In environments subject to rain, snow, or exposure to corrosive gases and media, a corrosion-resistant model is recommended.
Product Advantages
Reliable and Safe Braking: The interlocking mechanism ensures uniform retreat distances, preventing uneven wear or floating brake linings, ensuring consistent and reliable braking performance.
Low Maintenance: The self-lubricating bearings require no maintenance during operation, reducing the need for lubrication and minimizing maintenance costs.
Quick and Easy Brake Lining Replacement: The card-insertion system for brake linings and blocks makes replacements faster and safer, reducing downtime and optimizing operational efficiency.
Applications
The TWZ(B) Series Normally Open Foot-Pedal Operated Drum Brake is ideal for use in the slewing structures of various medium and small-sized portal cranes and tower cranes. The brake is especially effective in preventing unwanted movement and ensuring safe operation during non-working states.
Conclusion
The TWZ(B) Series Normally Open Foot-Pedal Operated Drum Brake with a manual clutch device provides a high-performance and reliable solution for crane systems. Its advanced interlocking mechanism, self-lubricating bearings, and easy-to-replace brake linings ensure safe, efficient, and low-maintenance operation. This brake is an essential component for improving the safety and reliability of crane operations in diverse industrial settings.
