The SBD-A safety brake has become the preferred choice for lifting machinery, with its essential safety design, strong braking performance, strong environmental adaptability, and easy maintenance, fully meeting the core requirements of lifting machinery for safety, reliability, efficiency, and low operation and maintenance costs.
Core safety design, in line with the essential requirements of lifting conditions
- Normally closed+disc spring braking, reliable failure protection: adopting a normally closed design, braking is achieved by applying force from a specially designed disc spring under normal conditions, and released by hydraulic drive; When there is a power outage, voltage loss, or other malfunction, the disc spring immediately pushes the clamp body brake to prevent serious accidents such as heavy objects falling or slipping, which is the core guarantee of lifting safety.
- Fast braking response and efficient emergency braking: With short braking time and sensitive action, it can output stable braking force in a very short time, reducing the risk of sudden situations during lifting operations, especially suitable for emergency braking needs of lifting and amplitude changing mechanisms.
- Comprehensive monitoring and interlocking: It can be equipped with switches such as opening limit and pad wear limit, and fault display and interlocking protection can be achieved through PLC, which facilitates early warning and timely troubleshooting, avoiding operation with defects.
Advantages of brake performance and working condition adaptation
- Strong and stable braking force: specially designed for low-speed shafts (drum shafts), with braking force covering 72KN-220KN, suitable for the heavy load requirements of large and medium-sized cranes; The asbestos free hard friction pad has a stable friction coefficient, a smooth braking process, and does not damage the brake disc.
- Outstanding environmental adaptability: Friction pads are insensitive to water, salt spray, etc. The sealing structure and imported seals ensure long-term stable operation and longer service life in humid, dusty, and corrosive environments such as ports, metallurgy, and mines.
- Compact structure and flexible installation: It can adapt to brake discs of different specifications, with no limited installation position, and can be flexibly integrated into the lifting and variable amplitude mechanisms of lifting machinery, suitable for various crane models.
Operations and Cost Advantages
- Easy maintenance and low cost: automatic compensation for pad wear, no need to frequently adjust clearances; Strong universality of components, simple replacement and maintenance process, reducing downtime and maintenance costs.
- Long life design: asbestos free pads are wear-resistant, imported seals enhance protection, the overall structure is durable, reduces replacement costs for long-term use, and fits the characteristics of high-frequency operation of lifting machinery.
Widely applicable scenarios
- It is mainly used for low-speed shaft emergency braking of large and medium-sized cranes, port loading and unloading machinery, mining winches, etc. It is particularly suitable for the harsh working conditions of special lifting equipment such as casting cranes and is the mainstream selection for safe braking of lifting machinery.
