Working Principle
Hydraulic fail-safe disc brakes are designed to ensure safety in the event of a system failure or power loss. These brakes use a spring to apply the braking force and hydraulic pressure to release the brake. When the system detects an anomaly or power failure, the spring immediately pushes the brake block against the rotating brake disc, achieving rapid braking. This design ensures that even under the most adverse conditions, the movement of the machinery can be quickly stopped and accidents prevented.
