A lift system for moving a car along a track in a guided manner. The lift system having a guide rail system, a car and a drive unit arranged on the car. The guide rail system forms a closed track along which the car can be moved between floors when in operation. The drive unit has a motor, a gear wheel system connected to the motor by a shaft and a guide disk. The guide rail system has a pinion system and guide edges spaced apart from one another, which cooperate with the guide disk. When in operation, the motor drives the gear wheel system and the gear wheel system acts on the pinion system in order to move the car along the track in a guided manner.

Disclosed is a car mover, configured for autonomously moving an elevator car along a track beam in a hoistway lane, having: a car mover body; a drive wheel operationally connected a lateral side of the car mover body, and configured to rotate about a drive wheel axis; a first guide wheel operationally connected to the lateral side of the car mover body, wherein the first guide wheel is offset from the drive wheel so that, in operation: the first guide wheel engages a lateral sidewall of the track beam when the drive wheel laterally moves on the track beam, to thereby restrict lateral motion of the drive wheel on the track beam.

A robotic transporter system for elevator cars including: a propulsion system configured to move an elevator car through an elevator shaft; and a robotic transporter configured to move the elevator car within a parking area, the robotic transporter including: an elevator containment slot to receive the elevator car and the propulsion system of the elevator car when the elevator containment slot is aligned with the elevator shaft.

A transport mechanism for transporting a travel body that can self travel and includes: a motor; a drive wheel to which rotary torque of the motor is transmitted; and a first gear to which the rotary torque of the motor is transmitted is provided. The transport mechanism includes: a transport body configured on which the travel body is placed for transportation, the transport body including a second gear that can mesh with the first gear of the placed travel body; a movement mechanism for moving the transport body, on which the travel body is placed, by the rotary torque of the motor transmitted to the second gear; and an idling section for causing an idle state in which the drive wheel rotates idle in a state where the first gear and the second gear mesh with each other and rotation of the second gear is permitted.

An elevator system including a hoistway, an elevator car disposed in the hoistway, the elevator car including a first braking device configured to engage a first braking surface in a first direction in the event of a guidance occurrence, and a second braking device configured to engage a second braking surface in a second direction in the event of the guidance occurrence.

An illustrative example embodiment of an elevator includes an elevator car and a drive mechanism connected with the elevator car. The drive mechanism moves with the elevator car in a vertical direction. The drive mechanism includes drive members that are configured to engage surfaces associated with walls near opposite sides of the elevator car, climb along the surfaces to selectively cause movement of the elevator car, and selectively prevent movement of the elevator car when the drive members remain in a selected position relative to the wall.
