Safety Brakes for Roller Shutters: Essential Protection for People and Property

Safety is paramount when it comes to the operation of roller shutters—particularly in commercial, industrial, and high-traffic environments. One of the most critical components ensuring safe operation is the safety brake. At HVP Security Shutters, we supply and install roller shutters equipped with robust safety brake systems, designed to protect both users and assets in the event of a mechanical failure.

What Is a Safety Brake?

A safety brake is a centrifugal braking device fitted to roller shutters, especially those powered by electric motors. Its primary function is to arrest the shutter’s descent if the motor or its operational brake fails. This prevents the shutter from dropping suddenly and uncontrollably, which could otherwise result in serious injury, equipment damage, or compromised security.

How Does a Safety Brake Work?

Normal Operation: During routine use, the shutter is held in position by the motor’s operational brake.

Failure Scenario: If the operational brake fails (for example, due to a mechanical fault or power loss), the shutter may begin to descend under its own weight.

Activation: The safety brake detects when the shutter is descending at an abnormal speed. Using centrifugal force, it immediately engages to halt the downward movement.

Electrical Isolation: Many modern safety brakes are also fitted with a micro-switch. When the brake activates, this switch disconnects the motor from the electrical supply, preventing further operation until the system is inspected and reset.

Resetting or Replacing a Safety Brake

Once a safety brake has been triggered, it must be reset or replaced before the shutter can be used again. This is a specialist procedure that should only be carried out by a qualified and experienced roller shutter engineer. Attempting to reset or replace a safety brake without proper training can compromise the safety of the system and may invalidate your warranty.

Why Are Safety Brakes Important?

Prevents Injury: Stops the shutter from free-falling, protecting anyone beneath or near the door.

Protects Property: Prevents damage to vehicles, stock, and equipment located below the shutter.

Compliance: Safety brakes are a legal requirement on many commercial and industrial roller shutters under UK and European safety regulations.

Peace of Mind: Ensures your roller shutter system is as safe as possible, even in the event of an unexpected failure.
