(23) In the preferred embodiment, as
(24)
(25) Each said loading device 4 and said loading and unloading device 5 is a motor driven conveyor comprising a conveying track T on top of which the container can be moved supported by the conveying track T. The conveying track T comprises one or more rotatable elements 23 as more specifically illustrated in
(26)
(27) Obtaining the destination floor information (such as a floor code) indicating the destination floor of the container 9 facilitates that the control system 11, preferable more specifically the sub-control system 30 for controlling operation of the goods elevator GE, can automatically move the load receiving unit 7 vertically in the elevator shaft 6 to the destination floor of the container 9 loaded thereon.
(28) Generally, it is preferable that the obtaining the destination floor information (such as a floor code) indicating the destination floor (F1-Fn) of the container 9 is performed by a sub-control system 30 of the control system 11, which sub-control system 30 is configured to automatically operate the elevator goods elevator GE. It is possible that a different part of the control system 11 already possesses the destination floor information of the container 9, but for facilitating automatic moving the load receiving unit 7 vertically in the elevator shaft S to the destination floor of the container 9 loaded thereon, it is preferred that the sub-control system 30 configured to control operation of the goods elevator GE obtains the destination floor information indicating the destination floor.
(29) Preferably, the obtaining the destination floor information indicating the destination floor of the container 9 identified in the order is performed when it is at the loading floor F0 or at least partially on the load receiving unit 7. Thus, the sub-control system 30 responsible for elevator operations obtains this information in time so that it can carry out transporting the container 9 to a correct floor. The destination floor obtained can be provided by the aforementioned determining the destination floor of the container 9 using the data detected from the identification 10.
(30)
(31) Each said unloading device 6 and said loading and unloading device 5 is a conveyor comprising a conveying track T on top of which the container 9 can be moved supported by the conveying track T. The conveying track T preferably comprises one or more rotatable elements 23 as more specifically illustrated in
(32) Generally, it is preferable that the transporting device 3 for moving the container 9 at least horizontally to a container loading floor F0 of the building 1 under construction is a motor driven conveyor comprising a conveying track T on top of which the container 9 can be moved supported by the conveying track T. The conveying track T preferably comprises one or more rotatable elements 23 as more specifically illustrated in
(33)
(34) The solution can be implemented also with different means for transportation. The transporting device 3 for moving the container identified in the order at least horizontally to a container loading floor F0 of the building 1 under construction can for instance comprise an automated guided vehicle configured to travel automatically a route between the storage 8 and the loading floor F0.

Presence of an automatic door (i.e. a door opening and closing movement which is motor driven under control of a control system) 22 is not necessary when transporting said containers 9 with the goods elevator GE. However, such a door 22 is a typical requirement for convenient and safe use for passengers. Preferably, opening and closing movement of said automatic door 22 is motor driven under control of a control system. This control system may be for instance a newly installed control system or the control system 11 used during the method for transporting construction material and/or construction equipment into and inside a building 1 under construction or a part thereof such as the aforementioned sub-system 30 as such or as modified, in particular to fit into passenger elevator use. After said constructing, the method comprises using the passenger elevator car 9 to transport passengers between floors of the building 1. Said using passenger elevator car comprises receiving call signals from user interfaces and moving the passenger elevator car 9 in response to said call signals.
(38) Generally, it is preferable that the load receiving unit 7 of the elevator for transporting goods GE does not comprise an automatic door, possibly not a door at all, as it is the case in the illustrated examples.
(39) The load receiving unit 7 of the goods elevator need not be provided with closed space, accordingly it is advantageous, although not necessary, that is does not comprise an interior delimited by floor, walls, ceiling and an automatic door.
(40) In context of said transition between construction time arrangement and the final arrangement in the building 1, the covers 23 of the shaft opening, which covers may be manual or automatic doors 23 for instance, can also be replaced with automatic doors 24. It may not be necessary to use covers 23 for covering the shaft opening 21, for instance if passage to the shaft S is efficiently blocked by other means e.g. by fences.
(41) Preferably, the load receiving unit of the elevator for transporting goods is vertically movable along one or more vertically oriented guide rail lines in an elevator shaft during said method for transporting construction material and/or construction equipment into and inside a building 1 under construction.

Thus, transformation of the goods elevator to form a passenger elevator in its place is performed utilizing components of the goods elevator, which facilitates swiftness and economy of the transformation. In a preferred embodiment, one or more components comprised in the goods elevator car, such as one or more of a car frame, guide members, such as roller guides or slide guides, a transport platform, are utilized in the constructing a passenger elevator car in place of the goods elevator car. In this case, preferably said constructing a second passenger elevator car in place of the goods elevator car is performed such that one or more of a car frame, guide members, such as roller guides or slide guides, a transport platform form corresponding part(s) of the passenger elevator car. Thus, transformation of the goods elevator to form a passenger elevator in its place is performed utilizing components of the goods elevator, which facilitates swiftness and economy of the transformation.
(43)
(44) In the preferred embodiment, the method further comprises determining storage position of the container 9 identified in the order, e.g. based on data stored in a database D. Such data can associate a storage position for each container 9 stored in the storage 8. The database D can be stored in the control system 11, such as a main control system 100 thereof or in a cloud 101, for instance.
(45) Said retrieving the container 9 identified in the order from the storage 8 comprises automatically moving the aforementioned transporting device 2 to the proximity of the storage position determined and thereby to proximity of the container 9 identified in the order, and automatically picking up the container from said storage position with the transporting device (2), and automatically transporting the container (9) away from its storage position with the transporting device (2). Thereby automatic retrieving of the containers 9 is facilitated.
(46) Preferably, said automatically transporting the container (9) away from its storage position with the transporting device (2) comprises automatically placing the container 9 to be carried by another transporting device, such as a transporting device 3 for moving the container at least horizontally to a container loading floor (F0) of the building (1) under construction. Thereby automatic passing of the container 9 further in the process is facilitated.
(47) The step of automatically transporting the container (9) away from its storage position with the transporting device (2) can also comprise, e.g. prior said placing the container 9 to be carried by another transporting device, automatically carrying the container (9) away from the storage (8, whereby automatic transport of the container 9 out from storage is achieved.
(48)
(49) In
(50) Structurally the picking up equipment 2b can be designed in many alternative ways. It could for instance be a pair of forks, in which case the transporting device 2 can be for example an automatically operable forklift, which can push its forks below a container 9 and lift it up. In
(51) Preferably, a detector 18a is mounted on the transporting device 2, which detector 18a is configured to detect identifications 10 of containers 9 and/or identifications 24 of storage positions when the transporting device 2 is retrieving a container 9 identified in the order from the storage 8.

(56) In the arrangement presented in
(57) The destination floor information (such as a floor code) indicating the destination floor of the container 9 identified in the order may or may not be included in the order, this being optional, since the destination floor information (such as a floor code) indicating the destination floor can be obtained also separately from said obtaining the order, e.g. when the container 9 identified in the order is at the loading floor F0 or at least partially on the load receiving unit 7.
(58) The control system 11 comprises one or more detectors 18a,18b,18c for detecting the identifications 10 of the containers 9. Such detectors facilitate automatic operation of the transporting devices since in this way the control system 11 can monitor and control progress of delivery of the container 9 identified in the order. For this purpose, it is preferable that the one or more detectors 18a,18b,18c are automatically operated by the control system 11.
(59) In
(60) In the preferred embodiment illustrated in
(61) In the preferred embodiment illustrated in
(62) In the preferred embodiment illustrated in
(63) In the preferred embodiment illustrated in
(64) Generally, the obtaining an order identifying a container 9 to be delivered is performed by the control system 11. Preferably, said obtaining comprises receiving an order signal s from an equipment 21 communicating with the control system 11. This makes it possible that orders are sent to the control system 11. This facilitates that the order can come based on need or schedule that is not known by the control system 11. For example, a construction worker can order from the storage 8 at an optimal moment construction material and/or equipment that is needed at the constructions site. In the preferred embodiment illustrated in
(65)
(66) Although preferable, it is not necessary that the control system 11 is configured to receive an order signal s from an external source since alternatively (or additionally) it can be configured to make orders itself, e.g. based on a schedule stored on the control system 11 itself.
(67) Generally, the method and arrangement according to the invention are advantageous in context where the construction site is large and potentially high in traffic, such as when the building under construction is tall. The advantages are most considerable in this kind of context and scale. For this reason, preferably, said different destination floors F1-Fn include at least 5 different destination floors, preferably more, such as more than 10 different destination floors, possibly more than 20 different destination floors, possibly even more than 50 different destination floors. In the arrangement, an while performing the method, respectively, the building under construction can be, although this is not necessary, relatively high, such as more than 100 meters high, for example. The building 1 under construction can be a tower building which rises during the construction. The invention is, however, advantageous also in cases where the building under construction has already reached its final height. For the aforementioned same reason, it is also preferable that said storage 8 stores more than 20, preferably more than 50, more preferably more than 100, of said containers.
(68) Generally, it is preferable that each said identification 10 of a container stores or presents in a detectable manner an identification code of the container in question and/or its destination floor code.

Preferably, each storey comprises plurality of adjacent storage positions each suitable for receiving a container 9. The storage preferably comprises an identification 24 per each storage position identifying the storage position in question.
(71) In
(72) Preferably, the containers 9 are such large that the interior of each container is at least 4 m3 in volume, preferable larger. Thus, they can all serve for transporting inside them various different large objects. The width height and length of each container are each at least 1 m, preferable larger.
(73) Preferably, the body of the container comprises metal, preferably majority (i.e. more than half) of its weight is produced by metal material. This means that the containers 9 are metal containers and they are durable for use in many construction sites.
(74) The bodies 9a of each of the containers 9 preferably delimits an interior where the construction material and/or equipment stored by the container 9 are positioned, and the interiors 9b of the containers 9 are preferably of same or at least substantially same size and shape.
(75) Generally, it is preferable that the aforementioned elevator shaft S is a space inside the building. This is advantageous since in this way, the construction time vertical transport as described can simply be performed using a space which can safely and efficiently used also for passenger transport of the elevator of the final building. The elevator shaft S is preferably a space surrounded by walls W of the building, said walls preferably being concrete walls.
(76) Generally, it is preferable that the identification codes of the containers 9 are different from each other.
(77) Preferably, said one or more detectors comprise plurality of detectors within the building under construction at spaced apart locations, preferably including one or more of: a detector 18a in the storage, a detector 18b at the loading floor F0, a detector 18c on the load receiving unit, a detector 18d at one or more destination floors F1-Fn. This facilitates tracing of the container 9 during its transportation.
(78) The detectors 18a-18d are preferably more specifically such that each said detector 18a-18d has a detection range, whereby detection of an identification 10 of a container 9 within the detection range indicates that the container 9 is within the detection range and thereby the location of the container 9. The detector is preferably an RFID-detector in which case the identification equipment 10 preferably comprises an RFID-device such as an RFID-tag. The detector can alternatively be for instance a so called Bluetooth device.
(79) The database D preferably stores a location code associated with the identification code of each container, the location code preferably indicating location of the container 9 in question. This facilitates monitoring of the location of the container 9 during its transportation.
(80) The database D can be stored physically anywhere as long as it is accessible sufficiently reliably. Preferably, it is stored in a cloud 101 comprised in the control system 11.
(81) The database D is preferably readable by a user interface program installed on a mobile communication device 21, such as a phone or a tablet.

(84) A program installed on a mobile communication device 22, such as a phone or a tablet is preferably configured to detect a change in location code of a container 9. The program can preferably further be configured to indicate, e.g. on a display thereof, to the user of the mobile communication device 22 an alarm or the updated location of the container 9.
(85) As mentioned, the conveying track T preferably comprises one or more rotatable elements 23 which can be rotatable rollers, for instance. In this case, the rollers preferably comprise a line of rollers with parallel rotational axes so that a container 9 can be moved supported by the conveying track linearly. A more sophisticated implementation of a conveying track can be used, where omnidirectional movement on the conveying track can be achieved, for example using a conveying track comprising so called omni-directional movement modules such as known from a commercially available Omnidirectional Cellular Conveyor, for example.
