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.

Abstract: An elevator car (102) including at least one barrier (110) extending from an external surface (106, 108) of the elevator car (102). The elevator car (102) further includes a switch (208) connectable in series with a safety chain circuit. The at least one barrier (110) is configured to be displaced from a first position (202) to a second position (204) upon contact with an object (120), such that the displacement to the second position (204) opens the switch (208) to initiate an emergency stop procedure of the elevator car (102).

Abstract: An elevator car is provided and includes a car frame which translates along a guide rail during ascents or descents, a safety disposed along the car frame to selectively engage with the guide rail to selectively permit vertical elevator car movement, an electronic safety actuator (ESA) and a control system. The ESA actuates the safety and includes an ESA body secured to the car frame with horizontal maneuverability and defining a groove through which the guide rail translates during the vertical elevator car movement, a magnetic guide operably disposed within the groove to exert magnetic force on the guide rail and a sensor disposed within the groove to sense horizontal distance between the guide rail and corresponding portions of the ESA body. The control system controls the magnetic guide to exert a magnetic force in accordance with reading of the sensor to maneuver the ESA body horizontally.

Abstract: Elevator systems are provided. The elevator systems include an elevator car movable along an elevator shaft having a pit floor and a shaft top, the elevator car having a car door lock arranged to enable opening of doors by a landing door lock mechanism when the elevator car is located at a landing and an elevator safety system. The elevator safety system includes a car door lock securing device arranged to prevent manual opening of the elevator car doors when in a first state and permits opening of the elevator car doors when in a second state and a car apron affixed to the car door sill and operable from a stowed state to a deployed state, wherein when the car apron transitions from the stowed state to the deployed state, the car door lock securing device is transitioned from the first state to the second state.

Abstract: Elevator systems having a first guide rail and a second guide rail, an overtravel feature on at least one of the first or second guide rails, the overtravel feature located a first distance from a top surface of the respective guide rail, an elevator car moveable along the first and second guide rails, the elevator car including a car guidance element, and a control unit configured to perform an overtravel distance test. The control unit is configured to measure a second distance being a distance of travel of the elevator car between a landing position and a location of the overtravel feature, combine the first distance and the second distance to calculate a measured overtravel distance, and compare the measured overtravel distance with a predetermined overtravel setpoint.
