A passenger/goods conveyor includes at least one transport entity connected with at least one mover, which co-acts together with at least one stator beam defining a movement trajectory for the transport entity. The at least one mover and the stator beam form a linear motor, the stator beam carrying on at least two opposite sides stator faces with stator poles which again co-act with corresponding mover counter faces including mover units facing the stator poles. The mover units are arranged successively in a running direction of the mover, whereby between the two stator faces and the corresponding mover counter faces air gaps are formed, whereby each mover unit includes electro-magnetic components configured to co-act with the stator poles to provide a propulsion force to accelerate and move the mover along the stator beam as well as an attraction force between the stator faces and counter faces to adjust both air gaps. In connection with at least one of the counter faces of the mover, at least one magnetic sensor is positioned facing the stator poles. Thus, the torque angle can always be calculated even after replacement of sensor or drive components.

A control system, installation, and methods for an elevator installation includes at least two elevator cars moveable in at least two shaft segments. The system has at least two shaft control units and at least two elevator car control units. Each of the shaft control units is configured to be respectively assigned to one of the shaft segments and each of the elevator car control units is configured to be respectively assigned to one of the elevator cars. The control system is configured to provide a mutual first communication link between the shaft control units. The control system is configured, for each of the shaft segments, to respectively provide a second communication link between the elevator car control units which are assignable to the elevator cars and the shaft control unit which is assignable to the respective shaft segment.

A system for allocating elevator use based on an individual request includes a request module that receives a reservation request of an elevator car from a user, an allocation module that identifies a reserved elevator car based on the reservation request; and a mechanical control module that moves the reserved elevator car in response to commands provided by the user and the reservation request.

A method for controlling car separation in a multi-car elevator system, the method including: initiating, by a controller, a change in a profile of a target elevator car; determining that N elevators cars are affected by the change in the profile of the target elevator car, wherein elevator car N is an elevator car farthest from the target elevator car; calculating for each of the N elevator cars an updated profile; for each of the N elevator cars, beginning with the Nth elevator car and ending with the target elevator car, performing: determining if the updated profile for the elevator car will provide separation between the elevator car and a neighboring elevator car; and when the updated profile for the elevator car will provide separation between the elevator car and the neighboring elevator car, executing an elevator car profile update process for the elevator car.

An elevator arrangement includes a plurality of elevators in a building, which plurality includes a plurality of zoned elevators moving in an elevator hoistway, which have different ranges of movement of the elevator car in the building to each other, and which zoned elevators each have a top limit and a bottom limit of the range of movement of the elevator car, to above the top limit and to below the bottom limit of which range of movement travel of the elevator car of the zoned elevator in question is prevented. The vertical location, in relation to the building, of the top limit and/or bottom limit of the range of movement of the elevator car of each aforementioned zoned elevator can be changed. The arrangement also comprises a lobby elevator, the range of movement of the elevator car of which differs from the ranges of movement of the elevator cars of the aforementioned zoned elevators, and the stopping floors of the lobby elevator comprise a plurality of lobby floors, each of which is a stopping floor of one or more zoned elevators belonging to the aforementioned zoned elevator plurality. A method is provided for re-adjusting the elevator arrangement, wherein the range of movement of the elevator car of the zoned elevator in question is changed to reach to a different height in the elevator hoistway by changing the vertical location in relation to the building of the top limit and/or the bottom limit of the range of movement of the elevator car of the zoned elevator in question.

An elevator system is a one-shaft double-car elevator system and includes a floor-recognition abnormality detector to detect, with respect to one of the cars, a floor recognition abnormality that at least one of a car position and floor information cannot be normally recognized, a terminal-floor driving mechanism to make, on the basis of a notification of floor-recognition abnormality information detected by the floor-recognition abnormality detector, the other one of the cars travel to a terminal floor in a direction opposite to a direction toward the one of the cars, and a floor-recognition-abnormality correcting-operation mechanism to perform, on the basis of terminal-floor traveling information from the terminal-floor driving mechanism, a floor-recognition-abnormality correcting-operation to correct the floor recognition abnormality of the one of the cars; therefore, an operation to recover from the abnormality can be safely performed without collision of the cars.

An elevator system may include upper and lower shuttle cars in a first shaft. The shuttle cars are at least at times fixedly coupled to one another and can move vertically upward and downward together. Upper and lower distribution cars in a second shaft may be movable vertically upward and downward separately. The upper shuttle and upper distribution cars may each comprise a stopping point at an upper shuttle level. The lower shuttle and lower distribution cars may each comprise a stopping point at a lower shuttle level. The second shaft may include a first stop element that can selectively limit a driving range of the upper distribution car to the upper shuttle level and a range vertically above it. A second stop element in the second shaft may selectively limit a driving range of the lower distribution car to the lower shuttle level and a range vertically below it.

A car mover for autonomously moving an elevator car along a lane in a hoistway, including: first and second wheels of the car mover, configured to apply a pinch force against a track therebetween and to rotationally drive along the track, by respective first and second wheel motors of the car mover; and a controller configured to execute: a lateral clearance control self-learning module, wherein based on adjustment data, one or more operational parameters applied by one or more of the first and second wheel motors are adjusted; and a lateral clearance feedback control module, wherein based on one or more of a first lateral clearance adjacent the first wheel on the track and a second lateral clearance adjacent the second wheel on the track, torque applied by one or more of the first and second wheel motors is increased or decreased.
