Abstract:
An elevator system including a braking system, and a method of retrofitting an elevator for such braking system is disclosed. The braking system may comprise a first brake having a first magnetic brake coil, the first brake movable between a disengaged and an engaged position, a second brake having a second magnetic brake coil, the second brake movable between a disengaged and an engaged position, and a brake control device having a brake power source. The brake control device may be electrically connected to the first and second brakes and may be configured to selectively delay or sequence the movement of the first brake and the second brake to the engaged position with residual current from the brake coils.
