The operating brake of type RH is designed as an active lever brake that operates pneumatically and is spring-opened. This means that in normal operating conditions, the forces from integrated springs keep the brake open, preventing the generation of braking torque. Only when compressed air is supplied through the pneumatic system is the active lever brake actuated, creating the desired braking torque. This design ensures safe and controlled braking, as the spring pack reliably opens the operating brake, and only the targeted use of pneumatics activates the braking force. Active lever brakes such as the RH types are primarily used in systems where fast and precise operation of the brake is required.
