A method of adjusting a load setting of an elevator car that includes receiving one or more load measurements associated with the elevator car and determining a maximum load of the elevator car from the one or more load measurements. The method further includes generating a modified load setting for the elevator car based on the maximum load and replacing the load setting of the elevator car with the modified load setting.

The invention relates to an elevator system comprising: an elevator car; at least one motor operable in two modes wherein in the first mode the at least one motor is consuming electrical energy and in the second mode the at least on motor is generating electrical energy; at least one rechargeable battery coupled to the at least one motor; wherein the at least one rechargeable battery is configured to be charged with an energy generated by the at least one motor when the motor is in the second mode.

An elevator that incorporates a framework that allows multiple autonomous mobile lifts to move independently inside and outside a building or a group of buildings in shafts and corridors in such a way that multiple lifts can share a shaft and/or corridor.

A method for operating an elevator system having a shaft system and elevator cars that are moved separately between floors in a circulation operation may involve moving the elevator cars upward in a first shaft and moving the elevator cars downward in a second shaft. A number of shaft positions that can be respectively adopted by the elevator cars and that correspond to the number of elevator cars is defined, and synchronization of movement of the elevator cars may be carried out with respect to these defined shaft positions. Further, each of the elevator cars may be moved according to a travel curve. To synchronize the movement of the elevator cars the travel curve for each elevator car may be adapted to account for positions of the elevator cars in the same shaft.

The present disclosure relates to a lift system including at least one lift shaft and a plurality of lift cars which can be individually moved. A plurality of the lift cars can be moved in the same lift shaft. The lift system further includes a control system for controlling the lift system. The lift cars of the lift system each have a unique identifier, for example an RFID transponder or a QR code. The disclosure further relates to a method for operating a lift system of this kind.

A multicar elevator system includes a plurality of elevator sub-systems, each elevator sub-system including a shaft forming a loop path including a first vertical section and a second vertical section connected to each other with at least two horizontal sections. The first vertical section in each elevator sub-system is travelable upwards by at least one elevator car and the second vertical section is travelable downwards by at least one elevator car. The elevator system further include a reservation shaft accessible for at least one elevator car from each elevator subsystem. A method for controlling the multicar elevator system is disclosed.

An elevator system includes a first elevator car (28) constructed and arranged to move in a first lane (30, 32, 34) and a first propulsion system (40) constructed and arranged to propel the first elevator. An electronic processor of the elevator system is configured to selectively control power delivered to the first propulsion system (40). The electronic processor includes a software-based power estimator configured to receive a first weight signal and a nm trajectory signal for calculating a power estimate and comparing the power estimate to a maximum power allowance. The electronic processor is configured to output an automated command signal if the power estimate exceeds the maximum power allowance.

An elevator system includes: an elevator control; a plurality of individually movable elevator cars driving in an elevator runway system including at least one elevator runway, preferably at least two elevator runways, whereby the number of elevator cars is higher than the number of elevator runways in the runway system. The elevator cars are movable in the elevator runway system via at least one drive system. Each of the elevator cars is provided with an identifier. The elevator system includes at least one reader device for the identifier and a car handling module in the elevator control processing the information on the elevator cars and their identifiers in connection with their position in the elevator system. The elevator system includes elevator cars differing in at least one parameter (differing parameter). The memory of the elevator control includes car parameters of the cars in operation in the elevator system and the elevator control is configured to use the car parameters in the control of the elevator system. The identifier includes information at least about the differing parameter, and the car handling module is configured to put out of use the car parameters of an elevator car that is to be put out of operation and/or to introduce the car parameters of an elevator car which is to be put into operation.

An elevator system includes a plurality of elevator cars, an elevator controller communicatively coupled to the plurality of elevator cars. The elevator controller is configured to generate a signal to a first elevator car for indicating an elevator call to the first elevator car. The first elevator car is configured to, in response to a receipt of the signal, initiate a communication with at least one second elevator car for receiving information relating to a status of the at least one second elevator car, and in response to a receipt of the information, generate a control signal with respect to serving the elevator call received by the first elevator car. A method for controlling an elevator car in the elevator system is also disclosed.

A method and system for managing an elevator system (10), includes providing at least one elevator car (14) to travel in a hoistway (11), and selectively introducing and removing the at least one elevator car (14) to and from the hoistway (11) via an intermediate transfer station (50) disposed at an intermediate floor location, wherein the intermediate transfer station (50) includes a service lift (54).
