Abstract:
The invention relates to a lift installation (1) comprising a lift cage supporting frame (2) that can travel in a travel space (3) provided for a journey of the lift cage supporting frame (2). Said lift installation is also provided with a first lift cage (15) and a second lift cage (16) arranged on the lift cage supporting frame (2). Furthermore,a hydraulic moving element (24) is arranged in a lower end region (22) of the travel space (3). In this way, the first lift cage (15) can be moved in relation to the second lift cage, by the moving device (24), in the lower end region (22) of the travel space (3).
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:
A method for allocating destination calls in an elevator system, said elevator system comprising at least one multi-deck elevator, in which method the passenger gives his/her destination floor by means of a destination call device at the beginning of the journey route, defining the starting point and final point of the passenger's journey route in the elevator system, which method comprises the steps of generating possible route alternatives from the starting point to the final point of the passenger's journey route, determining a cost function containing at least one travel time term, determining the value of the travel time term corresponding to each route alternative in the cost function, calculating the total cost of each route alternative by using the cost function, allocating for the passenger the route alternative that gives the minimum total cost and guiding the passenger to a waiting lobby and/or elevator consistent with the route alternative allocated.
Abstract:
Elevator cabs A-C move upwardly through three or more contiguous overlapping hoistways 38-40 in the upper decks of double deck car frames 41-43, and move downwardly through the hoistways in the lower decks (or vice versa). To switch between decks, the cabs are offloaded from the hoistways into auxiliary elevators 50, 51 at the terminal ends of the shuttle, and are moved to be adjacent to the other deck by the auxiliary elevator and loaded thereon for the trip in the opposite direction. A second embodiment has additional auxiliary elevators 64, 65 and additional cabs D, E so that loading and unloading of passengers do not delay movement of the cabs in the hoistways.
