Spring-applied brakes

Synonym(e) / Plural(e)
  • Spring-applied brake

An electromagnetic spring-applied brake, also known as an electromechanical brake or electric spring-applied brake, is a mechanical safety brake that generates a reliable braking torque through the force of pre-tensioned compression springs. This design is often referred to as a fail-safe brake, as it automatically acts as a spring-applied brake in a de-energized state - i.e. without electrical voltage. The springs press the friction surfaces together and thus ensure an immediate braking effect. The brake is only released electromagnetically and allows movement when a specific current is applied.

As a holding brake or power-off brake, this technology is primarily used in applications where safe stopping or emergency braking in the event of a power failure is crucial. Its use is particularly widespread in mechanical engineering and automation technology, for example in CNC machines, robotics or handling systems, where it enables precise positioning and emergency stops. It also ensures the safe holding or braking of loads in conveyor technology and logistics, such as roller conveyors, belt conveyors or storage technology.

In elevator and escalator technology, the electromagnetic spring-applied brake is used as a safety brake in emergencies or in the event of a power failure. The packaging industry uses them to control movement sequences in packaging machines and to stop them immediately in the event of malfunctions. In wind turbines, it is used both as a working brake for rotor positioning and as an emergency brake for maintenance work.

The electromagnetic spring-applied brake is also used in medical technology, for example in diagnostic devices or operating tables, to ensure precise and safe movements. It also ensures that rollers or conveyor belts stop precisely in textile machines and printing plants.

The electromagnetic spring-applied brake therefore not only serves as a working brake for regular operating conditions, but also as a reliable safety brake in critical situations. Thanks to its robust design and independent operation without a power supply, it offers maximum safety in industrial applications where reliability and precise control are a priority.
