Preferably, the vertical movement ranges of the first passenger elevator car 3 and the goods elevator car 7 at least partially overlap (i.e. when viewed in horizontal direction), but most preferably they are the same as presented, or at least substantially the same. Vertical movement of the goods elevator car 7 is automatically controlled by an elevator control system 8;4′. The goods elevator car 7 preferably comprises at least a transport platform 7a. This may be sufficient since it does not need to fulfil requirements set for a passenger elevator. For example, it does not need to have a door, which enables efficient loading of heavy and large goods thereon, e.g. large transport containers.

[0056] The method further comprises using the first passenger elevator PE1 to transport passengers between floors F0,Fn of the building 1 under construction and using the goods elevator GE to transport goods between floors F0-Fn of the building 1 under construction. An advantage is that the efficiency of flow of people and goods is efficient and safe already during construction of the building 1. Requirements of passenger transport and goods transport being different, these operations can hereby be separated and optimized such that small amount of changes will be required in a later transition to serving needs of the final building.

[0057] In the preferred embodiment of FIG. 1, the first and second hoistway 2,6 are beside each other such that their heights at least partially overlap (i.e. when viewed in horizontal direction). Thus, they can be used to transport passenger and goods to same floors F0,Fn of the building under construction 1. Most preferably, their heights overlap completely as presented, or at least substantially completely, meaning that at least 80 percent of their heights overlap.

[0058] In the preferred embodiment of FIG. 1, the first and second hoistway 2,6 are separated by a concrete wall extending between them. However, it is not necessary to separate said hoistways by a structure between them, since the space between them could alternatively be empty. Also, alternatively the separation could be provided by a other structures that concrete wall, such as beams extending between the first and second hoistway 2,6.

[0059] The building 1 under construction is preferably such that it has not reached its final height yet, the upper parts thereof still being missing. Hereby, preferably during the method, the building 1 under construction is constructed to be higher, most preferably during the method new floors are constructed on existing floors of the building 1 under construction.

[0060] In the preferred embodiment of FIG. 1, each said elevator hoistway 2, 6 is a space inside the building under construction 1 wherein an elevator car can move vertically.

[0061] In the preferred embodiment of FIG. 1, each said elevator hoistway 2, 6 is delimited by one or more inner walls W of the building 1, said walls W preferably being concrete walls.

[0062] The first passenger elevator car 3 is preferably vertically movable along one or more vertically oriented guide rail lines 15 in the elevator hoistway 2. Likewise, preferably the goods elevator car 7 is vertically movable along one or more vertically oriented guide rail lines 16 in an elevator hoistway 6.

[0063] In said using the first passenger elevator PE1 to transport passengers between floors of the building under construction; and said using the goods elevator to transport goods between floors (F0-Fn) of the building under construction 1, the first passenger elevator car 3 is preferably moved by a first motor M1 arranged to move a first roping 12 connected with the first passenger elevator car 3. Correspondingly, the goods elevator car 7 is preferably moved by a second motor M2 arranged to move a second roping 14 connected with the goods elevator car 7. The motors M1 and M2 can be arranged to engage the first and second roping 12, 14, respectively, via a drive sheave 11,13.

[0064] FIG. 2 illustrates an arrangement as provided at a phase of the method, which phase follows the phase illustrated in FIG. 1.

[0065] The method comprises, subsequent to using the first passenger elevator PE1 and the goods elevator GE a period of time, constructing a second passenger elevator PE2 in place of the goods elevator GE, as presented in FIG. 2. Said constructing comprises constructing a second passenger elevator car 9 for transporting people in place of the goods elevator car 7, wherein the second passenger elevator car 9 is vertically movable beside the first passenger elevator car 3 in an elevator hoistway 6, i.e. the second elevator hoistway, vertical movement of the second passenger elevator car 9 being controllable by an elevator control system 4′, and in which constructing a second passenger elevator car 9 the second passenger elevator car 9 is made to comprise an interior delimited by floor, walls, ceiling and at least one automatic door 10; and thereafter using both the first and second passenger elevator to transport passengers between floors F0-Fn of the building 1.

[0066] The door 10 being an automatic door makes the car 9 well suitable for safely serving of passengers, in particular for ensuring closing and opening doorway of the elevator car 9. Opening and closing movement of said automatic door 10 is preferably automatically controlled by the aforementioned elevator control system 4′ controlling the vertical movement of the second passenger elevator car 9.

[0067] In said constructing a second passenger elevator car 9 in place of the goods elevator car 7, the second passenger elevator car 9 is preferably arranged to be vertically movable along one or more of the vertically oriented guide rail lines 16 of the goods elevator car 7. Thus, transformation of the goods elevator GE to form a second passenger elevator PE2 in its place is performed utilizing the hoistway 6 as well as components of the goods elevator GE.

[0068] Likewise, it is preferred that said constructing a second passenger elevator car 9 in place of the goods elevator car 7 is performed such that one or more of a car frame 24, guide members 25, such as roller guides or slide guides and a transport platform 7a form(s) corresponding part(s) of the second passenger elevator car 9.

[0069] Thus, transformation of the goods GE elevator to form a second passenger elevator PE2 in its place is performed utilizing components of the goods elevator GE, which facilitates swiftness and economy of the transformation. Some of the referred features are optional and illustrated in FIG. 6.

[0070] FIG. 3 illustrates optional details for the solution presented in FIG. 1, according to a first preferred alternative, for controlling vertical movement of the first passenger elevator car 3 and the goods elevator car 7, as well as movement of the automatic door 5 of the first passenger elevator car 3. In this embodiment, vertical movement of the first passenger elevator car 3 and vertical movement of the goods elevator car 7 are automatically controlled by different elevator control systems 4 and 8, respectively. FIG. 3 also illustrates the door machinery 5a for moving the automatic door 5 of the first passenger elevator car 3.

[0071] In the embodiment of FIG. 3, said using the first passenger elevator PE1 comprises receiving by an elevator control system 4 first signals s1 associated with the first passenger elevator; and said using the goods elevator GE comprises receiving by an elevator control system 8 second signals s2 associated with the goods elevator; and said using the first passenger elevator PE1 comprises automatically controlling by the elevator control system 4 vertical movement of the first passenger elevator car 3 only in response to the first signals s1 of said first and second signals s1, s2, and said using the goods elevator GE comprises automatically controlling by the elevator control system 8 vertical movement of the goods elevator car 7 only in response to the second signals s2 of said first and second signals s1, s2.

[0072] FIG. 4 illustrates optional details for the solution presented in FIG. 1, according to a preferred second alternative, for controlling vertical movement of the first passenger elevator car 3 and the goods elevator car 7, as well as movement of the automatic door 5 of the first passenger elevator car 3. In this embodiment, vertical movement of the first passenger elevator car 3 and vertical movement of the goods elevator car 7 are automatically controlled by the same elevator control systems 4′. FIG. 4 also illustrates the door machinery Sa for moving the automatic door S of the first passenger elevator car 3.

[0073] In the embodiment of FIG. 4, said using the first passenger elevator PE1 comprises receiving by an elevator control system 4′ first signals s1 associated with the first passenger elevator; and said using the goods elevator GE comprises receiving by an elevator control system 4′ second signals s2 associated with the goods elevator GE; and said using the first passenger elevator PE1 comprises automatically controlling by the elevator control system 4′ vertical movement of the first passenger elevator car 3 only in response to the first signals s1 of said first and second signals s1, s2, and said using the goods elevator GE comprises automatically controlling by the elevator control system 4′ vertical movement of the goods elevator car 7 only in response to the second signals s2 of said first and second signals s1, s2.

[0074] In the preferred embodiment of FIG. 4, the first and second signals s1, s2 are received from different signal sources 17, 18, as showed in FIG. 1. Hereby, at least during a period when the first passenger elevator is in use to transport passengers between floors of the building under construction and the goods elevator is in use to transport goods between floors F0-Fn of the building under construction, the first and second signals s1, s2 are received from different signal equipment. This is advantageous, since it facilitates simplicity of the arrangement for calling a specific elevator in the building under construction 1, and special requirements of these different elevators can be simply met, e.g. with regard to positioning of components. For instance, many of the requirements of the goods elevator GE may be temporary. Hereby, the configuration of the devices for calling the goods elevator GE can be simply made temporary to be later modified. Hereby, for instance route of the goods to the goods elevator can be taken into account. The devices of the passenger elevator need not be dangerously close to the route of the goods to the goods elevator GE. Also, the signal equipment can be different and/or operate differently. Signaling is implemented in FIG. 1 such that the first signals s1 are received from a first signal equipment 17, and the second signals s2 are received from a second signal equipment 18. Preferably, separation of signaling is facilitated further such that the first signal equipment cannot send the second signals s2, and the second signal equipment 18 cannot send the first signals s1. Although advantageous as described above, it is not necessary that the first and second signals s1, s2 are received from different signal sources 17, 18. One or more of the objects of the invention can be achieved despite the details of the signals, such as what kind of signals, and how and from where signals are received.

[0075] Generally, the first and second signal equipment 17,18 can be of any known kind. However, preferably, the first signal equipment 17 comprises a user interface operable by a user, such as a user interface comprising a touch screen or buttons. The first signal equipment 17 are preferably arranged to receive a selection input by the user. The first signal equipment 17 can comprise for instance a portable communication device, such as a mobile phone or a tablet, comprising said user interface operable by a user. Likewise, the second signal equipment 18 can comprise for instance a portable communication device, such as a mobile phone or a tablet, comprising said user interface operable by a user.

[0076] In general, it is preferable, although not necessary, that the signal equipment 17 and/or 18 comprises at least a user interface mounted immovably on the building 1 under construction. Thus it can be accessed and operated at a certain location near the elevator PE1,GE.

[0077] FIG. 5 illustrates optional details of FIG. 2, according to a preferred alternative, for controlling vertical movement of the first passenger elevator car 3 and the second passenger elevator car 9, as well as movement of the automatic door 5 of the first passenger elevator car 3 and movement of the automatic door 10 of the second passenger elevator car 10. In this embodiment, vertical movement of the second passenger elevator car 9 is controllable by the same elevator control system 4′ as vertical movement of the first passenger elevator car 3. Should the control have been earlier arranged in accordance to FIG. 3, the method may necessitate modifying the control systems. Should the control have been earlier arranged in accordance to FIG. 4, the method may not necessitate modifying the control system 4′.

[0078] In the embodiment of FIG. 5, said using both the first and second passenger elevator comprises receiving by the same elevator control system 4′ signals s3 associated with both of the first and second passenger elevator; and automatically controlling by the same elevator control system 4′ vertical movement of the first and second passenger elevator car 7, 9 in response to the signals s3 associated with both of the first and second passenger elevator. Thus, the same elevator control system 4′ decides can choose to move either one of the first and second passenger elevator PEI, PE2 in response to receiving a signal s3. Responding to a signal s3 by either one of the elevators is advantageous in this way is advantageous since they are both passenger elevators and a more sophisticated optimization is achievable when the same elevator control system 4′ can choose the best available elevator for responding to a signal from plurality of elevators. Of course, alternatively the first and second passenger elevator PE1, PE2 could be served in response to signals from different sources.

[0079] The traveling zone of the first passenger elevator PE1 and/or the goods elevator GE can be extended to reach higher during the method. Then, preferably the method comprises shifting the using of the first passenger elevator PE1 on one or more temporary pauses during each of which the traveling zone of the car 3 of the first passenger elevator PE is extended to reach higher and after which the using is continued. Likewise, preferably the method comprises shifting the using of the goods elevator on one or more temporary pauses during each of which the traveling zone of the car 7 of the goods elevator GE is extended to reach higher and after which the using is continued. Such extension is preferable when the height of the building 1 under construction rises during the method. If and when the traveling zone of one or both of the elevators PE1, GE is extended, it is preferable to utilize technology of so called ‘jump elevators’, for example. Then it is preferable to utilize in the method a movable support structure S for supporting the car 3,7 of the elevator PE1, GE in question, which support structure S is mounted in the hoistway 2,6 of the elevator PE1, GE in question such that can be lifted to a higher position in the hoistway 2,6. Additional length of roping 12,14 of the elevator PE1, GE in question is preferably also stored in a rope supply storage (not showed), such as one or more rope reels, wherefrom it can be supplied via a releasable rope clamp (not showed). There are also other kind of elevators the traveling height of which can be extended, where one or more of the above described features of a ‘jump elevator’ may be unnecessary due to different type of solution.

[0080] FIGS. 6 and 7 illustrate preferred, although optional, details of the goods elevator GE and the method. As illustrated, the method preferably, although not necessarily, comprises moving a load on to and/or from the goods elevator car 7 using a loading device 19 mounted on top of a floor F0,Fn of the building 1 under construction in front of an opening 21 leading to the hoistway 6 in which the goods elevator car 7 is movable and/or using a loading device 22 mounted on top of a transport platform 7a of the goods elevator car 7. Thus, efficiency of the goods elevator GE specialized for goods transport can be further facilitated. Particularly, loading of heavy objects, such as transport containers, is facilitated to the extent that transport becomes quick, safe and simple to make at least partially automatic.

[0081] Preferably, this is implemented such that the loading device 19;22 comprises a conveying track T on top of which the load L can be moved supported by the conveying track T, the conveying track T comprising one or more rotatable elements 23, such as one or more rotatable rollers, as showed in FIG. 7, or alternatively one or more rotatable belts or one or more rotatable chains on top of which the load can be moved supported by the one or more rotatable elements.

Preferably, the control system (4 in FIG. 3; 4′ in FIG. 4) controlling vertical movement of the first passenger elevator car 3 is configured to receive first signals s1 associated with the first passenger elevator PE1 for enabling using the first passenger elevator PE1 to transport passengers between floors of the building 1 under construction, and to control vertical movement of the passenger elevator car 3 only in response to the first signals s1 of said first and second signals s1,s2; and the control system (8 in FIG. 3; 4′ in FIG. 4) controlling vertical movement of the goods elevator car 3, is configured to receive second signals s2 associated with the goods elevator for enabling using the goods elevator GE to transport goods between floors of the building 1 under construction, and to control vertical movement of the goods elevator car 6 only in response to the second signals s2 of said first and second signals s1,s2.

[0084] In general, the goods elevator car 3 is preferably made very simple and optimized for goods transport in a building under construction 1 without fulfilling requirements of a passenger elevator car, namely requirements of passenger elevator safety codes. Also many common requirements of an end user of a passenger elevator need not met. In the preferred embodiments presented, the goods elevator car 3 is made simple and it does not comprise an interior delimited by floor, walls, ceiling and an automatic door. One or more lateral sides of the goods elevator car can thus be open and/or the upper side of the goods elevator car can thus is open. In general, it is preferable that the goods elevator car 3 does not comprise an automatic door, e.g. one opening and closing movement of which is automatically controlled by an elevator control system. Actually, it is even more preferable that the goods elevator car 3 does not comprise a door at all, since hereby loading of the goods elevator car 3 is quick and efficient. Of course, a landing door can be used nevertheless for blocking access to the hoistway 6 when the goods elevator car 3 is absent from the floor in question.

[0085] The arrangement comprises a first signal equipment 17 for sending first signals s1 to a control system 4;4′ and a second signal equipment 18 for sending second signals s1 to a control system 8;4′. Preferably, separation of signaling is facilitated such that the first signal equipment 17 cannot send the second signals (s2), and the second signal equipment 18 cannot send the first signals s1.

[0086] Generally, the first and second signal equipment 17,18 can be of any known kind.
