Abstract:
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.
Abstract:
A plurality of express shuttle elevators S1-S4 exchange elevator cabs at a transfer floor 26 with local elevators L1-L10 by means of a carriage 107, the casters of which 93 are guided by tracks 70-83. The transfer floor has linear induction motor (LIM) primary segments 60-67 disposed on the transfer floor; the carriage has a LIM secondary 128 thereon for propulsion. The carriages can be locked 91, 92 to the transfer floor for loading, and cabs can be locked 131 onto the carriages for stability when being moved. A controller (Figs. 10-13) keeps track of the progress of the cabs from one elevator to another.
Abstract:
An elevator system for up-peak servicing of a building having a dual lobby. The system includes a controller having an electronic processor coupled to a memory, a plurality of elevator cars controllably connected to the controller, and a dual lobby routine stored within the memory. The dual lobby routine includes instructions for dispatching (125) at least one of the elevator cars to a lower lobby during up-peak, indicating (130) a sector assigned to the car, nudging (150) (if needed) the car if a lower lobby time-out is exceeded (135,145), dispatching the car to the upper lobby if a load weight threshold is not exceeded (155), and then indicating the sector assigned to the car while the car is located at the upper lobby.
Abstract:
The arrival of each of four dual-hoistway shuttle elevators S1-S4 is synchronized with a selected one of ten local elevators L1-L10, or ten low rise elevators L1-L10 and ten high rise elevators H1-H10 at a transfer floor 26 by limiting 140 the speed of the shuttle, gradually 149, or rapidly 154, 155 decreasing the speed of the shuttle, delaying a local elevator by holding its doors open for extra time, or controlling the speed of a local elevator, by cancelling or avoiding hall calls. Empty local elevators may be allowed to remain at the high end of the building, or compelled to travel to the lobby if needed. Elevators approaching a transfer floor may be synchronized by adjusting the speed of one of them until the remaining distance is the same for both. Hall calls may be prevented, cancelled, or negatively biased in dependence upon the tardiness of a local elevator. Synchronization may be achieved between shuttle elevators and local elevators, between portions of multi-hoistway shuttle elevators, and amongst elevator combinations employing three or more hoistways.

Abstract:
The invention relates to elevator systems, in which a number of elevators operate in the same hoistway. The elevator system comprises at least one shuttle elevator and at least two local elevators, the elevator cars of which are arranged to travel in the same elevator hoistway such that they can serve at least one shared transfer floor of a transfer level. The control system of the elevator system receives destination calls given from a destination call appliance, forms a plurality of route alternatives and allocates a destination call to one or more elevators by selecting the best route alternative. When allocating a destination call, the control system takes into account that the elevator cars of the local elevators that travel in the same elevator hoistway cannot simultaneously be at a shared transfer floor in cases in which the route alternative comprises a part-trip with a local elevator and a change of elevator at a shared transfer floor.
Abstract:
Die Erfindung betrifft ein Verfahren zur Auswahl des günstigsten Aufzugs einer mindestens zwei Aufzugsgruppen (GR) aufweisenden Aufzugsanlage, wobei zum Erreichen eines Zielstockwerks (Z) aus einem Startstockwerk (S) ein Weg (W1;..., Wn) mit Umsteigen (U1, U2, U3) verfügbar ist, der in mehreren Teilstrecken (W1T1,..., W1Tn; WnT1,..., WnTn) zerlegt wird und jeder der Teilstrecken (W1T1, ..., W1Tn; WnT1, ..., WnTn) ein Aufzug einer der Aufzugsgruppen (GR) zugeteilt wird. Mit diesem Verfahren wird unter anderem das Mehrwegproblem bei einer Zielruf-Multigruppensteuerung mit Umsteigefahrten gelöst.
