YW-L250/E23 Hoist Drum Brake, Normally Closed Safety Brake

Core Competitive Advantages

1. Fail-Safe Braking & Ultra-Stable Performance

Featuring a spring-engaged and electro-hydraulic released structure, the brake automatically locks tightly and triggers emergency braking once power failure, sudden shutdown or system abnormality occurs, completely avoiding equipment runaway, sliding and safety accidents. Equipped with E23 high-precision hydraulic thruster, it realizes smooth and gap-free braking and release actions, with no impact and no jitter during operation. The adjustable braking delay time (1-15 seconds via damping valve) meets the precise braking timing requirements of different equipment, ensuring consistent and reliable braking effect for long-term continuous operation.

2. Heavy-Duty Load Capacity & High Efficiency Heat Dissipation

Matched with 250mm standard brake drum diameter, the YW-L250/E23 brake outputs strong and stable rated braking torque, capable of bearing heavy load operation of large industrial equipment. The integral cast steel brake body enhances overall structural rigidity, resisting deformation and vibration during high-intensity operation. The optimized hollow heat dissipation structure accelerates air circulation, quickly takes away friction heat generated by frequent braking, effectively reduces thermal attenuation and friction pad aging, and greatly improves continuous working stability and service life.

3. Ultra-High Environmental Adaptability & Durability

The whole machine is designed with industrial-grade protection, with a protection grade up to IP65, effectively blocking dust, rain, moisture and industrial corrosive gas. It can work stably in a wide temperature range of -20℃ to +50℃, adapting to outdoor open-air, dusty factory workshops, humid port terminals and other harsh working environments. The friction pad adopts high wear-resistant and high-temperature resistant composite material, with low wear rate and long service life; the surface of metal parts is treated with anti-rust and anti-corrosion coating, which avoids rust and oxidation and reduces equipment failure rate in long-term use.

4. Low Maintenance & Cost-Effective Operation

The modular integrated structure design simplifies the overall mechanical structure, reduces redundant parts, and greatly lowers the probability of mechanical failure. The friction pad adopts a quick-disassembly structure, which can be replaced and maintained without disassembling the whole brake, saving maintenance time and labor costs. The E23 hydraulic thruster supports long-term stable operation with low energy consumption, no noise and low failure rate. Compared with traditional brakes, it reduces daily operation and maintenance costs by more than 30%, bringing long-term economic benefits to users.
