Understanding: Basics of fail-safe brakes for safety doors.
If a heavy safety door blocks the escape route in an emergency due to a power failure, there is a serious risk. A fail-safe manually releasable brake for safety doors can significantly improve plant safety. ATEK Drive Solutions offers suitable solutions and expert support for this.
The necessity of fail-safe brakes and manual release
A manual release is also of great importance for fail-safe brakes. In the event of a power failure, automatic systems could fail. Manual release allows for the opening of a safety door, even when other technical systems have failed. For example, a trapped employee can be freed faster after an emergency stop activation, which can shorten the response time. Basics of safety brakes.
Specific requirements for safety door brakes
Safety doors, especially in industrial environments, can weigh several hundred kilograms and must hold reliably in emergencies. The brake for safety doors must provide high holding forces and be designed for frequent switching cycles as well as a long service life, for example, over a million actuations. Precise design prevents premature wear and secures functionality. We assist in selecting the appropriate emergency stop brake..Recognizing: Functionality and technologies of manually releasable brakes
Das Fail-safe principle in these brakes, especially in a fail-safe manually releasable brake for safety doors, is usually based on spring pressure technology. Without a power supply, pre-tensioned springs press the brake pads together and generate the braking moment – a simple and reliable principle. Die manual release, often a lever, mechanically overcomes this spring force. For example, a technician can release the brake with a defined effort, about 150 Newtons. Mechanical brake details.
- Fail-safe principle: Is based on spring pressure technology for reliable function without power supply.
- Brake moment generation: Pre-tensioned springs press the brake pads together during a power failure.
- Manual release: A mechanical device (e.g., a lever) overcomes the spring force.
- Defined force effort: Allows technicians to manually release the brake (e.g., with about 150 Newtons).
- Preferred technology:Spring pressure brakes are often the first choice for fail-safety combined with easy manual release..
- Typical use: Especially relevant for electric drives and servomotors.
Types and technologies at a glance
In addition to Spring pressure brakes there are electromagnetic and hydraulic systems. For the combination of fail-safety and easy manual release, spring pressure brakes are often the preferred choice, especially in electric drives. ATEK Drive Solutions has a wide portfolio, such as the over 10,000 times integrated servomotors with spring pressure brakes illustrate.Application: Brakes for safety doors in industry and public spaces
Use in industrial facilities and machine construction.
These brake solutions, for instance, are used in manufacturing lines to secure heavy protective doors of machining centers or robot cells. A fail-safe manually releasable brake for safety doors allows quick access for maintenance or in case of malfunction, even when the system is powered off. ATEK has delivered over 500 such systems to the German machine building industry. Brakes for cranes.
Importance for public buildings and escape routes
Outside of industry, safety is also important, for example in heavy fire doors or safety locks in public buildings. Manual release ensures that escape routes remain passable even in the event of a complete system failure, which significantly contributes to personal safety. Emergency exit doors must be manually operable in accordance with DIN EN 179; a requirement that these safety brakes fulfill.Selecting: Ensure the right specifications and standards for brakes
