The energy sub-system is in electrical communication with the primary power source to buffer the first power and to generate a second power for powering a drive sub-system that drives the elevator car.

Disclosed is a ropeless elevator system having: a car mover operationally connected to an elevator car, the car mover configured to move along a car mover track in a hoistway lane, thereby moving the elevator car along the hoistway lane, wherein the car mover has a first tire of a first wheel that is configured to engage the car mover track when the car mover moves along the car mover track, wherein one or more of the first tire and the car mover track has an engagement feature for increasing traction between the first tire and the car mover track.

Disclosed is a ropeless elevator system having a car mover operationally connected to an elevator car, the car mover configured to operate autonomously and move along a hoistway lane, thereby moving the elevator car along the hoistway lane, wherein the car mover is connected to a top or bottom of the elevator car, via a coupling device.

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.

An elevator system including: an elevator car configured to travel through an elevator shaft; a first guide beam extending vertically through the elevator shaft, the first guide beam comprising a first surface and a second surface opposite the first surface; a propulsion system configured to move the elevator car through the elevator shaft; a first on-board energy management system configured to power the propulsion system, the first on-board energy management system is attached to the propulsion system and configured to travel with the propulsion system.

The invention relates to an elevator arrangement with multiple elevator cars in the same elevator shaft, the arrangement at least an uppermost elevator with its operating system, hoisting machinery and elevator car, and a lowermost elevator with its operating system, hoisting machinery and elevator car, which elevator cars are arranged to run in the same elevator shaft along the same guide rails. The types of the two elevators in the same elevator shaft are mutually different from each other.

A running system for an elevator. The running system comprises a car (21), running rails (1), and a driving mechanism, the car (21) is moved on the running mils by means of the driving mechanism, and the running system does not comprises a traction part. Further disclosed is a multi-car elevator running system: the running system is provided with a plurality of cats (21) and at least two set of running rails (1), and each set of running rails (1) can be used for the movement of line cars (21); the running system is further provided with at least one switching mechanism and driving mechanism, the car (21) is moved on the running rails (1) by means of the driving mechanism, different running rails (1) are connected by means of the switching mechanism, and the car (21) is switched to the different running rails (1) by means of the switching mechanism. By means of the configurations, the safety of the elevator during running can be enhanced, the high-speed running of the cars can be implemented, and the speed requirement of a high-rise elevator cart be satisfied.

An intelligent normal force release supervisor including: a processor; and a memory including computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations including: receiving a signal from a dispatching controller that an elevator car and a propulsion system are going to park for a selected period of time; requesting a confirmation from a brake controller to confirm that a brake system of the elevator car and the propulsion system are deployed; receiving the confirmation from the brake controller to confirm that the brake system of the elevator car and the propulsion system are deployed; and transmitting a command to a normal force controller to reduce normal force on wheels of the propulsion system, wherein the normal force controller is configured to actuate a normal force generator to reduce the normal force on the wheels of the propulsion system in response to the command.

A transportation system for a building with multiple floors includes a shaft in the building, a traction sheave drive type elevator and a lift. The elevator vertically conveys persons using an elevator car that is movable in the shaft together with at least two counterweights, the elevator car and the counterweights moving in opposite directions. The elevator car and the counterweights are driven by drive engines with traction sheaves. The lift vertically conveys objects and is designed as a self-propelled lift. The lift has a lift platform designed as a vehicle for supplying goods, which vehicle can be brought in and out the shaft and which lies, when located in the shaft, within a vertical projection of the elevator car.

According to an embodiment, an elevator system including: a beam climber system configured to move an elevator car through an elevator shaft by climbing a first guide beam that extends vertically through the elevator shaft, the first guide beam including a first surface and a second surface opposite the first surface, the beam climber system including: a first wheel; a second wheel; a first traction belt wrapped around the first wheel and the second wheel, the first traction belt being in contact with the first surface; and a first electric motor configured to rotate the first wheel, wherein the first traction belt is configured to rotate when the first wheel rotates.
