Lever brakes that close with spring actuation and open with hydraulic actuation are highly specialized braking mechanisms used in various industrial applications. The spring serves as the primary power source for closing the brake, ensuring reliable braking even in the event of hydraulic system failure. The hydraulic actuation for opening allows for controlled and precise release of the brakes. This design offers both safety and efficiency, as the brakes are always in the closed position due to the spring-based closing function and can only be opened by active hydraulic intervention.
