  • Elevator brake including coaxially aligned first and second brake members
    Patent number: 9637349
    Abstract: An example elevator brake includes a first braking member that is biased by a first spring member into engagement with a braking surface. The first braking member includes a first armature arranged to be actuated by an electromagnetic actuator to disengage the first braking member from the braking surface against the biasing force of the first spring member. A second braking member is biased by a second spring member into engagement with a braking surface. The second braking member includes a second armature arranged to be actuated by an electromagnetic actuator to disengage the second braking member against the biasing force of the second spring member. A first electromagnetic actuator actuates the first armature and a second electromagnetic actuator actuates the second armature.

  • Single brakeshoe test (electrical) for elevators
    Patent number: 8746413
    Abstract: A control arrangement (100) for an elevator brake, comprises a control circuit (110) adapted to generate, according to a demand for releasing a first braking member of the elevator brake, a first actuating signal and to generate, according to a demand for releasing a second braking member of the elevator brake, a second actuating signal; a first terminal (112) for outputting the first actuating signal to a first electromagnetic actuating means (26) of the elevator brake, a second terminal for outputting the second actuating signal to a second electromagnetic actuating means (30) of the elevator brake; the control arrangement (100) being adapted to allow at least the following modes of operation: A) a normal operation mode in which the first and the second actuating signals are supplied synchronously to the first and second electromagnetic actuation means (26, 30), respectively, and B) a single braking member test operation mode, in which one of the first and second actuating signals is supplied to the respect
