Abstract: An illustrative example embodiment of an elevator propulsion device includes at least one drive member configured to engage and climb along a vertical structure, a motor module including at least one motor configured to cause movement of the drive member and corresponding movement of an elevator cab, and a power supply including at least one energy source that is configured to provide power to the motor. The power supply is situated adjacent the motor module such that a mass of the at least one energy source provides a noise barrier to reduce transmission of noise from the motor into the elevator cab.

Abstract: An illustrative example embodiment of an elevator system includes a platform and a plurality of supports configured to selectively engage a nearby structure. The plurality of supports include at least a first support and a second support. The first and second supports alternate between engaging the nearby structure to support the platform while the other one of the supports is disengaged from the nearby structure. At least one of the first and second supports is configured to move relative to the platform while engaging the nearby structure to cause vertical movement of the platform.

Abstract: Elevator safety brake and/or safety actuator health monitoring systems and methods including an elevator car moveable within an elevator shaft along a guide rail, and a first safety brake assembly arranged on the elevator car and configured to engage with the guide rail to provide emergency braking to the elevator car. The first brake assembly includes a first safety brake and an electronic safety actuator operably connected to the first safety brake. A health monitoring element is in communication with the electronic safety actuator. The health monitoring element is configured to record information associated with operation of the first safety brake assembly, compare the recorded information against at least one predetermined threshold, and when the recorded information exceeds the at least one predetermined threshold, generate a notification that maintenance is required.

Abstract: An illustrative example embodiment of an elevator system includes a cab configured to accommodate at least one passenger or item inside the cab. A motorized module includes a base, a connector supported on the base and at least one drive member supported on the base. The connector is configured to selectively establish a releasable connection between the motorized module and the cab. The drive member is configured to engage a vertical surface, climb along the vertical surface to selectively cause vertical movement of the base, and selectively prevent movement of the base when the drive member remains in a selected position relative to the vertical surface. At least one motor is associated with the drive member to selectively cause the drive member to climb along the vertical surface. The motorized module is vertically movable independent of the cab when the motorized module is released from the cab.

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.
