3.1.1 General information
The spring-applied brake is designed for the conversion of mechanical work and kinetic energy
into heat. Due to the static brake torque, the brake can hold loads without speed difference.
Emergency braking is possible at high speed. The more friction work, the higher the wear,
(operating speeds

16).
The BFK455 spring-applied brake is a double disc brake with four friction surfaces. The braking
torque is generated within two electrically and mechanically separated braking circuits by
means of several compression springs (1.2) with friction locking. The braking circuits are
released electromagnetically. Due to its division into two braking circuits, the brake is
especially suitable for applications in the fields of lift technology and stage machinery. The
brake is selected on the basis of the characteristic torque for one braking circuit. The second
braking circuit meets the requirement for redundancy.
The braking circuits are divided by two separate armature plates (2) with the respective
compression springs (1.2) assigned and electromagnetic coils (8). The separate connecting
cables for each stator and armature plate render it possible to switch each braking circuit
individually,
