Abstract
Lift systems may include a first shaft unit and a second shaft unit, each of which may include a number of lift shafts. One or more single-car systems and/or multi-car systems may be disposed in the first shaft unit, whereas one or more shaft-changing multi-car systems may be disposed in the second shaft unit. A transporting operation may be carried out from an initial floor to a destination floor wherein a control unit determines whether to utilize one or more cars from the single car systems, the multi-car systems, the shaft-changing multi-car systems, or some combination thereof depending on factors such as the destination floors of the passengers, traffic density, energy demand, and/or availability of cars.
Claims20
A lift system comprising:
- a first shaft unit that includes a plurality of lift shafts;
- at least one of a single-car system or a multi-car system disposed in the first shaft unit;
- a second shaft unit that includes a plurality of lift shafts;
- a shaft-changing multi-car system disposed in the second shaft unit;
- and
- a control unit that determines whether to transport passengers to destination floors using the single-car system, the multi-car system, the shaft-changing multi-car system, or a combination thereof depending on at least one of the destination floors of the passengers, traffic density, energy demand, or availability of cars.
A lift system comprising:
- a first shaft unit that includes a plurality of lift shafts;
- a single-car system and a multi-car system disposed in the first shaft unit;
- a second shaft unit that includes a plurality of lift shafts;
- and
- a shaft-changing multi-car system disposed in the second shaft unit.
A lift system comprising:
- a first shaft unit that includes a plurality of lift shafts;
- at least one of a single-car system or a multi-car system disposed in the first shaft unit;
- a second shaft unit that includes a plurality of lift shafts;
- and
- a shaft-changing multi-car system disposed in the second shaft unit,
- wherein a car of the shaft-changing multi-car system of the second shaft unit is used as a feeder car in a first part-transporting operation where a passenger then changes cars prior to a second part-transporting operation that delivers the passenger to a destination floor.
A lift system comprising:
- a first shaft unit that includes a plurality of lift shafts;
- at least one of a single-car system or a multi-car system disposed in the first shaft unit;
- a second shaft unit that includes a plurality of lift shafts;
- and
- a shaft-changing multi-car system disposed in the second shaft unit,
- wherein the cars of the shaft-changing multi-car system are synchronized.
A lift system comprising:
- a first shaft unit including at least one lift shaft;
- at least one of a single-car system or a multi-car system disposed in the first shaft unit;
- a second shaft unit that includes a plurality of lift shafts;
- a shaft-changing multi-car system disposed in the second shaft unit;
- and
- a control unit that determines whether to transport passengers to destination floors using the first shaft, the second shaft, or a combination thereof depending on at least one of the destination floors of the passengers, traffic density, energy demand, or availability of cars.
A method for operating a lift system having a first shaft unit and a second shaft unit, the method comprising:
- transporting a passenger to a transfer stop by way of a shaft-changing multi-car system in the second shaft unit;
- transporting the passenger from the transfer stop to a destination floor by way of a single-car system or a multi-car system in the first shaft unit;
- and
- synchronizing the cars of the shaft-changing multi-car system.
