Abstract: An elevator safety device (120) is configured for restricting the movement of an elevator car (106) of an elevator system (102) along its pathway in order to prevent the elevator car (106) from moving beyond at least one limit position. The elevator safety device (120) is configured for performing at least one learning run (220a, 220b) for setting the at least one limit position.

Abstract: An elevator system 2 is provided which comprises: a hoistway 6 accessible by at least one hoistway door 10a, 10b, 10c; at least one elevator car 4 located in the hoistway 6; a hoistway door switch 12a, 12b, 12c associated with the at least one hoistway door 10a, 10b, 10c; at least one inspection switch 16; at least one emergency stop switch 18; and an elevator controller 24. The elevator controller 24 is configured to monitor the hoistway door switch 12a, 12b, 12c, the inspection switch 16 and the emergency stop switch 18 and to prevent inspection mode operation of the elevator car 4 until at least one change of state is detected of each of the hoistway door switch 12a, 12b, 12c, the inspection switch 16 and the emergency stop switch 18.

CPC classification number: B66B5/0087 , B66B5/027
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.
