Description

Technical Field

[0001] The invention relates to an elevator arrangement and a method for constructing an elevator. The elevator is preferably an elevator for transporting passengers and / or freight. Background Art

[0002] With so-called skip elevators, the bottom part of the elevator shaft is put into use before the building is completed. In this case, the upper part of the building and the top part of the elevator shaft can be built at the same time, because the elevator moving in the bottom part of the elevator shaft is already serving people on the lower floors of the building being built. Typically, in a skip elevator, during construction, the elevator car moving in the lower part of the elevator shaft is supported and moved by a hoisting machine supported on a machine room that can move vertically in the elevator shaft.

[0003] During use of the car for transporting passengers and / or freight beneath a movable support structure, the car may be suspended from a movable machine room by hoisting ropes.

[0004] Typically, construction work in a hoistway above a vertically movable machine room has been performed by working on a mounting platform suspended from above and movable above the movable machine room, or alternatively by working on a scaffolding installed in the hoistway.

[0005] When the elevator shaft being built above the vertically movable machine room has reached a sufficient stage of completion, the completed section of the elevator shaft can be put into service. At this stage, a "jump" is performed, in which the vertically movable machine room is lifted higher in the elevator shaft. Thereafter, the car can reach a higher position than before the jump and start serving additional floors.

[0006] In the prior art, one disadvantage is that the movable machine room is strong, large, heavy, and laborious to build and install in the hoistway and to move therein. One disadvantage is that it is difficult to find an alternative solution that works well and has one or more of the following characteristics: light weight, quick to build, simple to use for jumping, does not require a large number of solid support points, and can be quickly converted into the final elevator. One disadvantage is that the jumping process restricts the positioning of the lifting machine, making many layouts impractical. Summary of the invention

[0007] The object of the invention is to introduce an improved elevator arrangement and an improved method for building an elevator. One object is in particular to introduce a solution by which one or more of the above-mentioned disadvantages of the prior art and / or the disadvantages discussed or hinted at elsewhere in the description can be solved.

[0008] One object is in particular to provide a solution by which the top part of the elevator shaft can be built and / or its components installed simultaneously while the elevator car moving in the bottom part of the elevator shaft is already serving people on the lower floors of the building under construction, which solution is one or more of the following: light weight, fast to build, simple to use in a jump, does not require a large number of solid support points, and can be quickly converted into a finished elevator. Furthermore, an object is to provide a solution that also allows positioning the machine in a compact space.

[0009] A new method for building an elevator is proposed, which includes

[0010] Providing a lifting machine unit, the lifting machine unit comprising a lifting machine and a guide rail section, the lifting machine being fixed on the guide rail section;

[0015] installing one or more guide rail sections into the guide rail line above the guide rail sections of the lifting machine unit, in particular on top of the highest guide rail section of the guide rail line, to extend the guide rail line to reach higher; and

[0016] After said period of use, removing said lifting machine unit from said first position; and

[0017] installing a guide rail segment into the guide rail line at a location where a guide rail segment of a lifting machine unit is removed during said removal, the guide rail segment being installed preferably to have the same or at least substantially the same length as the guide rail segment of the lifting machine unit; and

[0018] Raise the lifting machine unit; and

[0019] installing the lifting machine unit to a second position higher than the first position, wherein the installing comprises placing a guide rail section of the lifting machine unit on top of the guide rail line; and

[0020] When the hoisting machine unit is in said second position, the elevator car is used (second use) for transporting passengers and / or freight.

[0021] With this solution, one or more of the above objects can be achieved. In particular, the elevator can be one or more of the following when built thereby: light weight, fast to build, simple to use for jumping and quickly converted into a final elevator. The method can also be implemented without the need to provide a large number of solid support points in the hoistway wall or other structure for anchoring the parts of the elevator that need to be lifted during the method.

[0022] Preferred further details of the method are presented below, which further details may be combined with the method alone or in any combination.

[0023] In a preferred embodiment, the method comprises providing a lifting arrangement which can be actuatable to lift and / or lower a guide rail section directly above a guide rail section of the lifting machine unit.

[0024] In a preferred embodiment, the method comprises, before removing the lifting machine unit from said first position, lifting a guide rail segment above a guide rail segment immediately adjacent to the lifting machine unit, in particular by actuating a lifting arrangement.

[0025] In a preferred embodiment, the guide rail section being installed has the same or at least substantially the same length as the guide rail section of the lifting machine unit.

[0026] In a preferred embodiment, during the process of lifting the guide rail sections, the guide section directly above the guide section of the lifting machine unit is lifted so that the guide section directly above the guide section of the lifting machine unit is raised from a state vertically supported by the guide section of the lifting machine unit, and / or a gap is formed or the gap is enlarged between the guide section of the lifting machine unit and the guide section directly above the guide section of the lifting machine unit.

[0027] In a preferred embodiment the method comprises between said removing and installing, vertically supporting with a lifting arrangement a guide rail segment previously located directly above the guide rail segment of the lifting machine unit, in particular for preventing it from falling into the position where the guide rail segment of the lifting machine unit was removed.

[0028] In a preferred embodiment, after said installing the guide rail segment into the guide rail line at the location where the guide rail segment of the lifting machine unit was removed during said removal, the method comprises lowering the guide rail segment which was previously directly above the guide rail segment of the lifting machine unit towards the installed guide rail segment. This lowering is preferably performed by actuating a lifting arrangement.

[0029] In a preferred embodiment, said lifting of the lifting machine unit is performed using a vertically movable working platform in the hoistway above the car.

[0030] In a preferred embodiment, the lifting and / or lowering is performed by one or more actuable lifting devices of the lifting arrangement. In particular, the aforementioned one or more actuable lifting devices are actuable to lift and / or lower the guide rail section directly above the guide rail section of the lifting machine unit.

[0031] Preferably, the aforementioned one or more actuatable lifting devices are supported by a guide rail section directly below a guide rail section of the lifting machine unit, preferably via brackets fixed to the guide rail section directly below the guide rail section of the lifting machine unit.

[0035] In a preferred embodiment, the method comprises, during said first and / or second use, installing elevator components from a working platform in a hoistway section above the elevator car. Preferably, said installing comprises installing one or more guide rail segments into the guide rail line above the guide rail segments of the hoisting machine unit, in particular on top of the highest guide rail segment of the guide rail line, to extend the guide rail line to reach higher. Preferably, said installing further comprises immovably fixing the guide rail segments with one or more brackets in the hoistway.

[0036] In a preferred embodiment, installing a guide rail segment into the guide rail line at the location where the guide rail segment of the lifting machine unit is removed during the removal process comprises: connecting the lower end of the guide rail segment to be installed to the upper end of the guide rail segment (1a) by means of a fixing element fixed directly to the upper end of the guide rail segment (1a), and connecting the upper end of the guide rail segment to be installed to the lower end of the guide rail segment (1c) by means of a fixing element fixed directly to the lower end of the guide rail segment (1c). The guide rail track 1a is here the guide rail segment that was previously located directly below the guide rail segment of the lifting machine unit, and the guide rail segment (1c) is the guide rail segment that was previously located directly above the guide rail segment of the lifting machine unit.

The embodiment with guide rail clamps provides good adaptability of the guide rail line to changes in building dimensions and easy fixing thereof. The embodiment with guide rail clamps also provides easy lifting and / or lowering of the guide rail section directly above the guide rail section 1b of the lifting machine unit.

[0038] In a preferred embodiment, consecutive guide rail sections of the guide rail line, to which the guide rail sections of the lifting machine unit belong, are immovably connected to each other, preferably by means of fixing members, such as fish plates, fixed directly to opposite ends of the consecutive guide rail sections.

[0039] In a preferred embodiment, the method comprises, after said installing the guide rail segments into the guide rail wire, removing the lifting arrangement and installing it to a higher position in the hoistway. Thus, it can be used later to remove the lifting machine unit from the second position.

[0040] In a preferred embodiment, said removing preferably comprises suspending said lifting machine unit with a hanger connected to said lifting machine unit and supported by a structure different from said guide rail line.

[0041] In a preferred embodiment, the first and / or second use comprises receiving a call signal from one or more user interfaces, such as one or more user interfaces and / or mobile user interfaces located at a floor and / or in an elevator car, by an elevator control system, the elevator control system being connected to a motor of a hoisting machine unit, and automatically controlling the rotation of the motor, thereby controlling the movement of the elevator car, in response to the call signal.

[0042] A new elevator arrangement is also proposed, comprising a hoistway; a hoisting machine unit, which is located in a first position in the hoistway, the hoisting machine unit comprising a hoisting machine and a guide rail segment, to which the hoisting machine is fixed; and one or more vertically oriented guide rail lines in the hoistway for guiding an elevator car or a counterweight, comprising a vertically oriented guide rail line for guiding an elevator car or a counterweight and comprising a plurality of guide rail segments, in particular guide rail segments stacked on top of each other, wherein the guide rail segment of the hoisting machine unit is one of the plurality of guide rail segments, and wherein the guide rail line comprises one or more guide rail segments located below the guide rail segment of the hoisting machine unit. The guide rail line comprises one or more guide rail segments above the guide rail segment of the hoisting machine unit; and the elevator arrangement comprises a hoisting arrangement, which can be actuated to lift and / or lower the guide rail segment directly above the guide rail segment of the hoisting machine unit.

[0043] With this solution, one or more of the above objects can be achieved. Thus, it is facilitated to move the lifting machine unit from said first position to a new position. Furthermore, it is facilitated to replace it with another guide rail segment. In particular, the elevator can thus be built to be one or more of the following: light, fast to build, simple to use for jumping and fast to convert into a final elevator. The method can also be implemented without the need to provide a large number of strong support points in the hoistway wall or other structures for anchoring the parts of the elevator to be lifted during the method.

[0044] Preferred further details of the elevator arrangement have been described above and will be described below, which further details may be combined with the elevator arrangement alone or in any combination.

[0045] In a preferred embodiment, the lifting arrangement can be actuated to lift the guide rail section directly above the guide rail section of the lifting machine unit, in particular such that the guide rail section directly above the guide rail section of the lifting machine unit is raised from being vertically supported by the guide rail section of the lifting machine unit and / or such that a gap is formed or enlarged between the guide rail section of the lifting machine unit and the guide rail section directly above the guide rail section of the lifting machine unit. Hereby, it is facilitated that the weight of the guide rail section above the guide rail section of the lifting machine unit can be lifted from being carried by the guide rail section of the lifting machine unit and / or additional gap can be provided. Hereby, moving the lifting machine unit from said first position to a new position is facilitated.

[0046] In a preferred embodiment, the lifting arrangement is actuatable to lower the guide rail section to directly above the guide rail section of the lifting machine unit. This facilitates that it can be lowered to rest on the guide rail section, thereby replacing the guide rail section of the lifting machine unit.

[0047] In a preferred embodiment, the lifting machine comprises a drive wheel for driving the lifting ropes and a motor for rotating the drive wheel.

[0048] In a preferred embodiment, the lifting machine is located between the guide rail section of the lifting machine unit and the hoistway wall when in the first and / or second position. The lifting machine is then located, in particular, on the side of the guide rail section opposite the elevator car when viewed from above. In this case, there is often insufficient space for removing and lifting the lifting machine to a higher position, so that the arrangement and the method are particularly advantageous when the lifting machine is so positioned.

[0049] In a preferred embodiment, one or more guide rail sections of the guide rail line (to which the guide rail section of the lifting machine unit belongs) are located (or are installed in the installation step of the method) above the guide rail section of the lifting machine unit, and are laterally immovably supported in the hoistway by one or more brackets, so that when the lifting machine is in the first position I and / or the second position II, the vertical projection of the one or more brackets overlaps the vertical projection of the lifting machine. In this case, the lifting of the lifting machine to a higher position is usually blocked by the brackets, so that the arrangement and the method are particularly advantageous in this case.

[0050] In a preferred embodiment, the guide rail segments of the guide rail line are stacked on top of each other.

[0051] In a preferred embodiment, each guide rail segment of the plurality of guide rail segments vertically supports the guide rail segment directly above it.

[0052] In a preferred embodiment, the elevator arrangement comprises a hoisting roping. Preferably, the ropes of the hoisting roping extend via releasable rope clamps into a rope supply reservoir in the form of one or more rope reels, from which additional rope required in the method can be taken out. For example, the rope supply reservoir can preferably be installed on a landing or in a pit of the hoistway.

[0054] In a preferred embodiment, the lifting arrangement comprises one or more lifting devices which can be actuated to lift and / or lower the guide rail section directly above the guide rail section of the lifting machine unit, preferably in particular via brackets fixed to the guide rail section directly above the guide rail section of the lifting machine unit. The advantage of lifting via said brackets is that the vertical forces required for lifting and / or lowering can be transferred to the guide rail section in a simple manner.

[0055] In a preferred embodiment, the lifting arrangement comprises one or more lifting devices which are supported by the guide rail section directly below the guide rail section of the lifting machine unit, preferably via brackets fixed to the guide rail section directly below the guide rail section of the lifting machine unit. This type of support has the advantage that the vertical reaction forces required for lifting and / or lowering can thereby be obtained in a simple manner.

[0056] In a preferred embodiment, consecutive guide rail sections of the guide rail line, to which the guide rail sections of the lifting machine unit belong, are immovably connected to each other, preferably by means of fixing members, such as fish plates, which are directly fixed to opposite ends of the consecutive guide rail sections.

[0057] In a preferred embodiment, each of the lifting devices is a hydraulic jack or a screw jack.

[0058] In a preferred embodiment, each of the lifting devices is actuatable to extend or retract in a vertical direction.

[0059] In a preferred embodiment the elevator arrangement comprises a hanger connected to the hoisting machine unit.Preferably the hanger is supported by a structure different from the guide rail wires.

[0060] In a preferred embodiment, the elevator arrangement comprises a second hoisting arrangement comprising a suspender and a second hoisting device, for example mounted on the working platform, and said suspender is movable by means of the second hoisting device.

[0061] In a preferred embodiment, the structure in addition to the guide rail line is a working platform which is vertically movable in the hoistway.

[0062] In a preferred embodiment, the lifting arrangement is actuable manually or by an automatic actuation system.

[0063] In a preferred embodiment, each of the lifting devices is actuable manually or by an automatic actuation system. In the first case, each lifting device is preferably actuable by manually operating a manual operating device to achieve lifting. Correspondingly, each lifting device is preferably actuable by manually operating a manual operating device to achieve lowering. For the purpose of manual actuation, the lifting arrangement preferably comprises manually operable actuating means. In the latter case, the arrangement may comprise an automatic actuation system.

[0064] In a preferred embodiment, the lifting arrangement comprises an operating interface operable to control actuation of the actuatable lifting arrangement.The operating interface is preferably in the form of an operating panel, such as a button panel or a touch screen.

[0079] Figure 1 An elevator arrangement A in one stage of a method for building an elevator according to one embodiment is shown. The arrangement A comprises a hoistway H and a hoisting machine unit 5 statically mounted in a first position I in the hoistway H. The hoisting machine unit 5 comprises a hoisting machine 6 and a guide rail segment 1b, to which the hoisting machine 6 is fixed. The guide rail segment 1b to which the hoisting machine 6 is fixed carries the entire weight of the hoisting machine 6. The arrangement A comprises a vertically oriented guide rail line 1 in the hoistway, which is a guide rail line for guiding a movable elevator unit, such as an elevator car 2 or a counterweight 3, and comprises a plurality of guide rail segments 1a, 1b, 1c stacked on top of each other. The guide rail segment 1b of the hoisting machine unit 5 is one of the plurality of guide rail segments 1a, 1b, 1c, and the guide rail line 1 comprises one or more guide rail segments 1a located below the guide rail segment 1b of the hoisting machine unit 5. Furthermore, the guide rail line 1 comprises one or more guide rail sections 1 a , 1 c located above the guide rail section 1 b of the lifting machine unit 5 .

[0080] The elevator arrangement A comprises a lifting arrangement 7 which can be actuated to lift and / or lower a guide rail segment 1c directly above the guide rail segment 1b of the lifting machine unit 5. Thus, it is facilitated to remove the lifting machine unit 5 from said first position I to move it to a new position. Furthermore, it is facilitated to replace it with another guide rail segment.

[0081] The lifting arrangement 7 is actuatable to lift the guide rail section 1c directly above the guide rail section 1b of the lifting machine unit 5, in particular to raise the guide rail section 1c directly above the guide rail section 1b of the lifting machine unit 5 from being vertically supported by the guide rail section 1b of the lifting machine unit 5 and / or to create a gap or enlarge the gap between the guide rail section 1b of the lifting machine unit 5 and the guide rail section 1c directly above the guide rail section 1b of the lifting machine unit 5. Thus, lifting the weight of the guide rail section above the guide rail section 1b of the lifting machine unit 5 from being carried by the guide rail section 1b of the lifting machine unit 5 and / or to provide additional clearance. Thus, removal of the lifting machine unit 5 from said first position I to a new position is facilitated.

[0082] Furthermore, the lifting arrangement 7 can preferably be actuated to lower the guide rail segment 1c directly above the guide rail segment 1b of the lifting machine unit 5, for example after lifting said guide rail segment 1b. This facilitates that it can be lowered to rest on the guide rail segment 1b of the lifting machine unit 5 or on the guide rail segment 1d replacing it.

[0083] Furthermore, the elevator arrangement A comprises hoisting ropes 4, and the hoisting machine 6 comprises a drive wheel 6a for driving the hoisting ropes 4, and a motor 6b for rotating the drive wheel 6a.

[0084] Furthermore, the lifting arrangement 7 preferably comprises one or more Figure 1 In the embodiment of , there are in particular two lifting devices 8. The lifting devices 8 can be actuated to lift or lower the guide rail segment 1c located directly above the guide rail segment 1b of the lifting machine unit 5, in particular via a bracket 9 fixed to the guide rail segment 1c.

[0085] Furthermore, the lifting arrangement 7 is preferably such that the lifting device 8 is supported by a guide rail segment 1 a directly below a guide rail segment 1 b of the lifting machine unit 5 , in particular via a bracket 10 fixed to the guide rail segment 1 a .

[0086] Each lifting device 8 is preferably a hydraulic jack. Figure 1 As shown. However, the lifting arrangement can also be implemented differently by any known lifting device, such as a screw jack or a scissor jack or possibly some other type of lifting device, such as a Tirak crane. In the case shown, each hydraulic jack 8 includes a hydraulic cylinder member 8a and a piston member 8b. In addition, each hydraulic jack 8 preferably makes the hydraulic cylinder member 8a include a hydraulic chamber (not shown), and the piston member 8b can move in the hydraulic chamber. Therefore, hydraulic fluid can be pumped into the hydraulic chamber or extracted from the hydraulic chamber to control the movement of the piston member 8b. In this case, the actuation of the lifting device 8 can include pumping fluid into the hydraulic chamber or extracting fluid from the hydraulic chamber. The actuation can be set to be performed manually or by an actuation system. In the first case, each hydraulic jack can be actuated to achieve lifting by manually operating a manual operating device, such as a hand pump (e.g., a pumping rod), and the user can pump hydraulic fluid into the chamber to achieve lifting by the manual operating device. Likewise, in the first case, the hydraulic jacks may be actuated to effect lowering by manually operating a manual operating means, such as a release valve, which releases the hydraulic fluid from the chamber to effect lowering. In the manual version, each lifting device may have its own manual operating means, or alternatively they may share one manual operating means, whereby synchronized actuation is possible. In the latter case, arrangement A may include, for example, Fig. 9An automatic actuation system 18 is shown, which preferably includes a hydraulic pump and a hydraulic valve system for actuating the hydraulic jack.

[0087] like Figure 1 As shown, the elevator arrangement A preferably also comprises a hanger 11 connected to the hoisting machine unit 5. Thus, it is facilitated to remove the hoisting machine unit 5 from its first position without risk of falling. The hanger 11 is supported by a structure 12 different from the guide rail line 1. Thus, when suspension is required, the vertical forces can be taken up by a structure other than the guide rail line 1 to which the guide rail segment 1b of the hoisting machine unit 5 belongs.

[0088] In addition to the guide rail line 1, the structure 12 is preferably a working platform 12 which is vertically movable in the hoistway H. In a preferred embodiment, this is implemented in such a way that the elevator arrangement A comprises a second lifting arrangement, which comprises the aforementioned suspender 11 and a second lifting device 14, which is for example mounted on the working platform 12 and the suspender 11 can be moved by the lifting device 14.

[0089] As mentioned above, Figure 1 An elevator arrangement A is shown in a stage of a method for building an elevator according to an embodiment. Figure 2-6 8 show preferred details of the arrangement A and its use. Preferably, the elevator arrangement A comprises an elevator car 2 and a counterweight 3; a hoisting rope system 4 connects the elevator car 2 and the counterweight 3 to each other. The passage of the elevator car 2 and the counterweight 3 and the hoisting rope system 4 is, for example, Figure 4 . Preferably, the ropes of the hoisting rope system 4 extend via releasable rope clamps 16 into a rope supply reservoir 15 in the form of one or more rope reels, from which additional rope can be taken if / when a jump is required. For example, the rope supply reservoir 15 can preferably be installed on a landing or in a pit in the hoistway.

[0090] like Figure 8 As shown, the lifting arrangement A may include an operating interface 500 operable to control the actuation of the actuatable lifting arrangement 7. The operating interface 500 is then preferably in the form of an operating panel, such as a button panel or a touch screen. Figure 8As shown, the operation interface 500 is preferably wirelessly or wiredly connected to the automatic actuation system 18 of one or more lifting devices 8. On the other hand, the automatic actuation system 18 is preferably connected to each of the one or more lifting devices 8. For example, when one or more lifting devices 8 are hydraulic jacks, the automatic actuation system 18 can be a hydraulic automatic actuation system. In this case, the automatic actuation system 18 will preferably include a hydraulic pump and a hydraulic valve system for actuating the hydraulic jack. If and when one or more lifting devices 8 are screw jacks, the automatic actuation system 18 can include an electric motor for actuating the screw jack.

[0091] like Figure 1 As shown, consecutive guide rail sections of the guide rail line 1 are connected to each other, for example by means of fixing elements 19, such as fish plates, which are fixed, for example by bolts, directly to opposite ends of the consecutive guide rail sections 1a, 1b; 1b, 1c. Figure 2 Shown from one side Figure 1 The fixing member 19 is at a stage where the connection of consecutive guide rail sections 1a, 1b; 1b, 1c has been released and the lifting machine unit 5 is being removed.

[0092] Figure 4 An elevator arrangement in a stage of a method for building an elevator according to an embodiment is shown.

The guide rail 1d is here the guide rail segment being installed, and the guide rail 1a is here the guide rail segment 1a that was previously immediately below the guide rail segment 1b of the lifting machine unit 5, and the guide rail segment 1c is the guide rail segment 1c that was previously immediately above the guide rail segment 1b of the lifting machine unit 5.

[0111] Preferably, the method comprises removing the lifting arrangement 7 after said installing the guide rail segment 1d in the guide rail line 1. The method may comprise installing it to a higher position in the hoistway H if further jumps are to be performed.

[0112] To facilitate repositioning of the rope fixings, the method preferably includes installing one or more rope fixings 17 and / or one or more rope clamps 16 on the working platform 12 so as to be lifted together with the working platform 12 to a higher position, such as Figure 5 This can be accomplished by installing support beams or equivalent (in Figure 4 The hoistway H is realized by a support beam (only partially shown) on which one or more rope fixings 17 and / or rope clamps 16 are attached to the working platform 12 to move upward with the working platform 12. After lifting, the one or more rope fixings 17 and / or rope clamps 16 can be reinstalled at a higher position in the hoistway H by reinstalling the support beam or equivalent to which the one or more rope fixings 17 and / or rope clamps 16 are attached. For example, the support beam or equivalent can be installed on the guide rail line 1 and / or the guide rail line 13 or their brackets, or on a separate bracket in the hoistway.

[0113] In order to facilitate easy adjustment of the rope length, in the method, during the lifting of the lifting unit 5, the lifting ropes 4 are preferably passed around the drive wheel 6a of the lifting unit 5. One or more rope clamps 16 are preferably opened during the lifting of the lifting unit 5, so that additional rope can be pulled out from the rope supply storage 15 via the one or more rope clamps 16, such as Figure 5 During the lifting process of the lifting unit 5, the upward movement of the drive wheel 6a can generate the said pulling of the additional rope.

[0114] like Figure 5 As shown, the method preferably includes suspending the car 2 on the working platform 12 so as to be lifted to a higher position by the working platform 12.

[0115] It is generally preferred that the guide rail line 1 comprises a plurality of guide rail sections 1a, 1b, 1c stacked on top of each other, preferably such that each or at least some of the guide rail sections 1a, 1b, 1c vertically supports the guide rail sections 1a, 1b, 1c directly above it.

[0116] It is generally preferred that the guide line 1 comprises guide rail sections 1a, 1c which are laterally immovably supported in the hoistway 2 by one or more brackets 20. Each of said brackets 20 preferably frictionally engages the guide rail sections 1a, 1c with a guide rail clamp 21, thereby allowing vertical movement of the guide rail sections 1a, 1c. The embodiment using the guide rail clamp provides good adaptability of the guide line to changes in building dimensions and easy fixation thereof. The embodiment using the guide rail clamp also provides easy lifting and / or lowering of the guide rail section 1c directly above the guide rail section 1b of the lifting machine unit 5. It is not necessary that each guide rail section of the guide line is laterally immovably supported by a bracket, as they can be connected to each other, for example, with fixing members 19.

[0117] The weight of a guide rail segment which is laterally immovably supported in the elevator shaft by one or more brackets may be carried entirely or at least partially by said brackets. Thus, the bottommost guide rail segment of the guide rail line does not need to carry the total weight of all the guide rail segments above it. However, when using guide rail clamps, the clamping force may vary and thus how much of the weight of each individual guide rail segment is carried by the clamp.

[0118] Typically, the term directly above guide rail segment 1b means guide rail segment 1c which is the next guide rail segment above the guide rail segment 1b in question, and the term directly below guide rail segment 1b means guide rail segment 1a which is the next guide rail segment below the guide rail segment 1b in question.

[0119] It is generally preferred that the hoisting ropes 4 are arranged to suspend the car 2 and counterweight 3 in a suspension ratio of 2: 1. However, this is not essential, as the ratio may alternatively be 1: 1, or possibly any other ratio.

[0120] It is generally preferred that the first and / or second use includes receiving a call signal from one or more user interfaces 90, such as one or more user interfaces and / or mobile user interfaces located at a floor and / or in an elevator car, by the elevator control system 100, the control system 100 being connected to the motor 6b of the lifting machine unit 5, and the elevator control system 100 automatically controlling the rotation of the motor 6b in response to the call signal, thereby controlling the movement of the elevator car 2. Fig.10 A user interface 90 of the hoisting machine 6 of the hoisting machine unit 5, an elevator control system 100 and a motor 6b are shown as well as their preferred connections.

[0121] Typically, in the preferred embodiment of the method and arrangement A shown, the lifting machine 6 is located between the guide rail section 1b of the lifting machine unit 5 and the wall of the hoistway H when in the first position I and / or the second position II. Then, when viewed from above, the lifting machine 6 is located in particular on the side of the guide rail section 1b opposite the elevator car 2. In this case, the space for removing the lifting machine 6 and lifting the lifting machine 6 to a higher position is usually insufficient, so that the method and device according to the invention are particularly advantageous when the lifting machine 6 is so positioned. However, even if the environment is different, one or more advantages can be achieved.

[0122] Typically, in the preferred embodiment of the method and arrangement A shown, one or more guide rail sections 1c of the guide rail line 1 are located (or are installed in the installation step of the method) above the guide rail section 1b of the lifting machine unit 5, and are laterally immovably supported in the hoistway H with one or more brackets 20, so that when the lifting machine 6 is in the first position I and / or the second position II, the vertical projection of the one or more brackets 20 overlaps the vertical projection of the lifting machine 6. In this case, the lifting of the lifting machine 6 to a higher position is usually blocked by the bracket 20, and therefore the method and arrangement A according to the invention are particularly advantageous in this case. However, even if the environment is different, one or more advantages can be achieved.
