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

The long stroke electromagnetic block brake relies on the main spring to apply and the electromagnet to release.

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

The advantage of electromagnetic block brakes is that they have a simple structure and 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.
