Twin-Circuit Spring-Operated Brakes

Emco Lenze offers Twin-Circuit Spring-Operated Brakes, BFK454. It is used for lift systems. It is of good quality. It is highly reliable. It is TUV-tested and meets the requirements of the TRA 200 or EN 81 for lift systems. The twin-circuit system is created by dividing the armature plate; the spring force that provides the braking torque acts: to 80% directly on the front armature plate and to 20% indirectly on the rear armature plate. The front armature plate is axially guided by the rear armature plate. Due to this design, at least the spring force acting directly on the front armature plate can be maintained in the case of a failure. Advantages: small dimensions, low moment of inertia, fast reduction of braking torque, depending on the operating conditions, easy maintenance and checking of the twin-circuit function, and friction surface not divided.
