Crane Brake

The brake is an important safety device of the crane, which is used to control the movement and stop of the crane to ensure the safety and reliability of the crane during operation.

Small cranes or light load material lifting, can choose electromagnetic brakes, it is fast response, high braking force and low braking noise, but vulnerable to electromagnetic interference and temperature. Large-tonnage cranes or high-load material lifting, it is more suitable for hydraulic brakes, which can provide strong braking force, excellent stability, but the maintenance cost is higher, the design is more complex. Mechanical brakes are often used in small lifting equipment or light load operations, with reliable braking force and low maintenance costs, but with high friction material requirements. The pneumatic brake is suitable for cranes that need fast response and low braking force requirements. It has fast braking response, good stability and long life, but it relies on large air pressure.

Block brake

• Large braking moment: it can produce a large braking moment, enough to meet the braking requirements of various crane mechanisms, especially for the lifting mechanism and the operation mechanism of a large crane, which can reliably prevent the fall of heavy objects and the movement of the crane.
• Simple structure: mainly composed of brake block, brake arm, brake wheel, spring and other components, the structure is relatively simple, easy to manufacture, install and maintain.
• Smooth braking: During the braking process, the friction between the brake block and the brake wheel gradually increases, making the braking process more stable and reducing the impact on the crane structure and cargo.
• Good heat dissipation performance: the contact area between the brake block and the brake wheel is large, the heat dissipation effect is relatively good, and it can maintain good braking performance in the case of frequent braking.

Disc brake

• Rapid brake response: Because the gap between the brake disc and the brake disc is small, and the motion of the brake disc is short, the disc brake can respond quickly to the brake command and achieve rapid braking.
• High braking accuracy: the braking pressure and braking torque can be precisely controlled, making the braking process of the crane more accurate, suitable for occasions with high braking accuracy requirements, such as the lifting of precision equipment.
• Good stability: the structure of the brake disc and the brake disc is relatively stable, and it is not easy to produce deformation and vibration during the braking process, which can ensure the consistency and stability of the braking performance.
• Easy maintenance: the brake disc is worn evenly, the replacement of the brake disc is more convenient, and the brake gap does not need to be adjusted frequently, reducing the maintenance workload.
