FAQs
1. What is an Industrial Roller Shutter Safety Brake?
An Industrial Roller Shutter Safety Brake is a mechanical safety device installed on rolling shutter doors to prevent the door curtain from falling uncontrollably if the motor brake fails, power is lost, a spring breaks, or another mechanical fault occurs. It acts as a secondary “fall-arrest” system, stopping the heavy door from dropping like a guillotine and protecting people and property.
2. How does a Roller Shutter Safety Brake work?
Most models are centrifugal brakes mounted on the roller shaft. During normal controlled operation, the brake stays disengaged. If the door descends at excessive speed, centrifugal force triggers the mechanism, which applies friction or locks against the shaft/guides to bring the door to a safe stop. Many include energy-damping features for a softer arrest and an electrical switch that cuts power when activated.
3. Is a Safety Brake legally required?
In the UK and EU, it is often mandatory or strongly recommended for doors weighing more than approximately 20 kg (especially those with pedestrian or vehicle access underneath) to comply with safety regulations such as DHF TS011, EN 12453, EN 12604, and Workplace Health & Safety requirements. A proper risk assessment is always advised.
4. Why is a Safety Brake necessary for industrial roller shutters?
Industrial doors are heavy and used frequently. If the primary motor brake or suspension components fail, the door can drop suddenly, causing serious injury, fatalities, or property damage. The safety brake provides essential backup protection beyond the motor’s built-in brake.
5. What types of Safety Brakes are available?
Common types include centrifugal shaft-mounted brakes, integrated brakes in direct-drive motors, cable-based fall-arrest systems, and torque-limiting devices. They come in different sizes and load ratings to match various door weights and widths. Some are resettable; others must be replaced after activation.
