MW630-5000 Electromagnetic Drum Brake Hengyang Heavy Industry Noisy

Due to the limitation of the electromagnetic attraction of the short stroke electromagnetic brake, the braking torque of the short stroke brake is generally not large. Mechanisms that require high braking torque often use long stroke electromagnetic drum brakes.

Hengyang Heavy Industry's long stroke electromagnetic drum brake relies on the main spring to apply and the electromagnet to release.

The commonly used long stroke electromagnetic drum brake is the JCZ type 200-600 brake. It is mostly used on Overhead crane of 20-30 tons or more.

The advantage of Hengyang Heavy Industry's electromagnetic drum brake is its simple structure, which can be interlocked with the control circuit of the motor. Therefore, when the motor stops working or an accident power outage occurs, the electromagnet can automatically power off and the brake will automatically switch on, ensuring safe and reliable operation. However, there is a major drawback that the electromagnet has a strong impact, causing severe braking on the mechanism and causing mechanical vibration of the transmission mechanism. At the same time, due to frequent starting and braking of the lifting mechanism, the electromagnet produces a huge collision sound, and the service life of the electromagnet is short, requiring frequent repair and replacement.
