An elevator communication system includes a first elevator controller; a second elevator controller; and a first ethernet bus portion connected to the first elevator controller, the first ethernet bus portion having sequential bus segments interconnected by at least one switch. The first ethernet bus portion is arranged in a first elevator shaft. A second ethernet bus portion is connected to the second elevator controller and includes sequential bus segments interconnected by at least one switch. The second ethernet bus portion is arranged in a second elevator shaft. A switch of the first ethernet bus portion and a switch of the second ethernet bus portion are interconnected to enable data transmission between the switch of the first ethernet bus portion and the switch of the second ethernet bus portion. The first elevator controller is communicatively connected to the second elevator controller.

An elevator system includes first and second elevator cars movable vertically in a first elevator shaft, a closed support belt routed around lower and upper deflection rollers, a drive machine driving the support belt, and an actuable coupling device arranged on each of the first and second elevator cars. The support belt has first and second coupling elements to and from which the coupling devices can be coupled and decoupled whereby a drive connection between the respective elevator car and the support belt can be established and released. A coupled elevator car is moved in the first elevator shaft by the support belt driven by the drive machine. The coupling elements are arranged such that they are not routed around the deflection rollers during movement of the first elevator car from a lower end position to an upper end position or vice versa.

An elevator system wherein a cab is moved within a shaft by a tractive drive system that transmits torque frictional force on the interior surface of the shaft, enabling the cab to travel without cables and travel for long distances. The tractive drive system automatically regulates these normal forces. A method of controlling a plurality of these cabs disposed within a plurality of shafts by means of electronic systems.

An elevator system includes an elevator car that is movable in an elevator shaft in the vertical direction, a closed support belt guided about a lower deflection roller and an upper deflection roller and a drive machine driving the support belt. A drive connection is made between the support belt and the elevator car with a coupling device arranged on the elevator car that is coupled to a coupling element of the support belt. The coupling element is a connection element that connects two free ends of the support belt together.

An elevator shaft element, an elevator arrangement and a method. The elevator shaft element comprises a frame module arranged for receiving an elevator car therein. The frame module is constructed from a transport and/or storage unit, comprising side walls, a bottom wall and a roof wall. The unit is arranged to be positioned vertically such that said side walls, bottom wall and upper wall of the unit define an inner space of the elevator shaft. Elevator car guides for guiding movement of the elevator car in the elevator shaft element are attached to said bottom wall and/or roof wall.

The present disclosure concerns a method for operating an elevator system which comprises a shaft system and at least three cars, which is designed for separately moving the cars in at least a first direction of travel and in a second direction of travel. The at least three cars are moved separately in sequential operation each time and for each car a stop point at which the car can stop if necessary is continuously predicted at least for one direction of travel. The distance of the predicted stop points of neighboring cars from each other is thereby continuously determined. The elevator system is transferred to a safety mode if a negative distance of the stop points is determined.

A wireless power transfer system for wirelessly powering a conveyance apparatus of a first conveyance system and a conveyance apparatus of a second conveyance system including: a wireless electrical power transceiver located along a surface of the conveyance apparatus of the first conveyance system, a wireless electrical power transceiver located along a surface of the conveyance apparatus of the second conveyance system, the surface of the conveyance apparatus of the second conveyance system being opposite of the surface of the conveyance apparatus of the first conveyance system, wherein the wireless electrical power transceiver of the first conveyance system is configured to wirelessly transfer electrical power to the wireless electrical power transceiver of the second conveyance system when the wireless electrical power transceiver of the first conveyance system and the wireless electrical power transceiver of the second conveyance system are located proximate to one another.

An elevator system includes a car, a main rope, a car, a detector, and a sway detection unit. The car moves vertically. The main rope moves as the car moves. The car moves vertically. The detector is provided on the car. The detector detects the position of the main rope. The sway detection unit detects, on the basis of the position detected by the detector, that abnormal swaying requiring a control operation is occurring in the main rope.

A method for operating an elevator system, which may include at least two cars that can move independently of one another within a common elevator shaft, may involve determining with an elevator controller to cause a first car of the at least two cars to perform a transportation process from a start stopping point to a destination stopping point. The elevator controller may determine a starting time and travel parameters according to which the first car carries out the transportation process from the start stopping point to the destination stopping point. The starting time and the travel parameters may be determined by taking into account state parameters of a second car of the at least two cars.

An elevator system may include a plurality of cars that are disposed vertically one above another in a common shaft. The plurality of cars may be independently movable. Further, the plurality of cars may include evacuation devices that permit the passage of passengers from a car to be evacuated into an adjacent car that is disposed vertically above or below the car to be evacuated. In some cases, an evacuation device of an uppermost car of the plurality of cars includes an opening floor hatch, and an evacuation device of a lowermost car of the plurality of cars includes an opening roof hatch.
