However, this is not necessary since if a different hoisting machine 5′ is installed to position II than to position I, this installation work can be started at the upper parts of the hoistway 1 already before said removing 400.
[0127] After said installing 500, the method comprises transporting 600 passengers and/or goods with the elevator car vertically in the hoistway while the hoisting machine is in said second position II, said transporting 600 comprising moving the elevator car with the hoisting machine and the second hoisting roping.
[0128] The steps of said removing 400 performed for the first roping 6 which occur between transportations 200 and 600 particularly facilitate achieving a simple, very swiftly installable, lightweight, and cost effective early usability to serve users with an elevator car moving in lower parts of an elevator hoistway very early after starting of construction work of the building. The roping and other structures can be kept simple and lightweight, e.g. because the suspension roping is changed between transportations 200 and 600.
[0129]
[0130] A first embodiment implementing the method described referring to
[0131]
[0132] In the preferred embodiment, said connecting of phase 100 comprises arranging the roping in question 6 to pass around a drive wheel of the hoisting machine 5 in question and suspend the car 3 and counterweight 15 on opposite sides of the drive wheel 17, preferably such that the roping 6 passes on a first side of the drive wheel 17 down to the car 3, around one or more rope wheels thereof and up to a rope terminal device 7, and on a second side of the drive wheel 17 down to the counterweight 15, around one or more rope wheels thereof and up to a rope terminal device 7.
[0133] In the preferred embodiment illustrated, said installing 100 a hoisting machine 5 in the first position comprises mounting the hoisting machine 5 on one or more guide rail lines 4a,4b to be supported vertically by said one or more guide rail lines 4a,4b. Said mounting may comprise fixing the hoisting machine 5 on an guide rail section forming part of an earlier installed part of a vertically oriented guide rail line 4a or prefixing the hoisting machine 5 on an guide rail section to be installed. Accordingly, the hoisting machine 5 may preferably, although not necessarily, be prefixed on a guide rail section so that these can be installed as a unit For this purpose, the method preferably comprises before said installing 100 a phase 90 of providing a hoisting machine unit U as illustrated in
[0134] In the preferred embodiment, the installing 100 comprises mounting a first support structure 10 in the hoistway 1 and suspending the elevator car 3 movably with an auxiliary hoisting arrangement 11,12 from the first support structure 10.

Preferably, the counterweight 15 is positioned at a lower end of the hoistway 1 while the performing installing work of said hoisting machine 5 and/or said first roping 6. Thus, the relative position of the car 3 and counterweight 15 is easily adjustable correctly at opposite ends of their movement zones, and such that the roping 6 is simply connectable to the car 3 and counterweight 15.
[0136] The method preferably comprises installing landing doors 9 before said transporting 200. Therefore, the aforementioned elevator components preferably include landing doors 9 and/or their structures (e.g. sills, frames horizontal guide rails when the landing doors are sliding doors).
[0137] The installing 100 preferably comprises using the roof top of the elevator car 3 as an installation platform for installing other elevator components (i.e. components other than said car 3) into the hoistway 1. Said other components preferably include the aforementioned hoisting machine 5 and/or the first roping 6, possibly landing doors 9 and/or their structures (e.g. sills, frames horizontal guide rails when the landing doors are sliding doors). Said using the roof top of the elevator car 3 as an installation platform comprises performing installation work by a person working on the roof top of the elevator car 3. Preferably, the method comprises at a suitable moment after said installing 100 displacing the auxiliary hoisting arrangement 11,12, and suspending a working platform 13 with said auxiliary hoisting arrangement 11,12 from a second support structure 14, which is higher than said first support structure 10.
[0138]
[0139] The method preferably comprises during said transporting 200 one or more of: [0140] installing guide rail sections on top of said one or more guide rail lines 4a,4b in portion of the hoistway 1 which is higher than said hoisting machine 5; [0141] installing landing doors 9 higher than said hoisting machine 5, in particular between floors and the hoistway 1, which floors are higher than said hoisting machine 5; [0142] constructing new floors into the building higher than said hoisting machine 5.
Thus, during said transporting 200, construction and/or installing work can be performed above the level of said first position I, at the same time as the car 3 operates serving needs below the level of said first position I.
[0143] Said installing guide rail sections on top of said one or more guide rail lines 4a,4b in portion of the hoistway 1 which is higher than said hoisting machine 5 and/or said installing landing doors between floors and the hoistway, which floors are higher than said hoisting machine 5 comprises moving a working platform 13 in a portion of the hoistway 1 which is higher than said hoisting machine 5, and in particular performing installation work by a person working on the working platform 13. Additionally or alternatively, an installation robot can perform installation work working on the working platform 13. The working platform 13 is preferably as described referring to
[0144] After said transporting 200, in particular after a period thereof, stopping 300 said transporting 200 is performed. This preferably comprises stopping the aforementioned automatically moving of the elevator car 3.
[0145] After said stopping 300, the method comprises removing 400 said hoisting machine 5 from said first position I and the first roping 6 from the hoistway 1, said removing 400 comprising disconnecting the first hoisting roping 6 from the elevator car 1 and counterweight 15.
[0146] The method further comprises installing 500 a hoisting machine 5;5′ in a second position II which is higher than the first position I, and a second roping 16 for being moved by the hoisting machine 5;5′ as illustrated in
[0147] In the preferred embodiment, said connecting of phase 500 comprises arranging the second roping 16 to pass around a drive wheel 17;17′ of the hoisting machine 5;5′ and suspend the car 3 and counterweight 15 on opposite sides of the drive wheel 17;17′, preferably such that the second roping 16 passes on a first side of the drive wheel 17;17′ down to the car 3, around one or more rope wheels thereof and up to a rope terminal device 7, and on a second side of the drive wheel 17;17′ down to the counterweight 15, around one or more rope wheels thereof and up to a rope terminal device 7.
[0148] The hoisting machine that is installed in said second position II in said installing 500 may be said same hoisting machine 5 earlier installed in and removed from said first position I in said installing 100. In this case, the hoisting machine 5 can be hoisted on top of the car roof to the proximity of the second position II. Alternatively, the hoisting machine 5 installed in the first position I is a first hoisting machine, and the hoisting machine 5′ installed in the second position II is a second hoisting machine. Then, the installation work of the hoisting machine 5′ can start already before the removing 400, which makes the remaining steps of the method swift and downtime can be minimized.
[0149] After said installing 500, the method comprises transporting 600 passengers and/or goods with the elevator car 3 vertically in the hoistway 1 while the hoisting machine 5;5′ is in said second position II, said transporting 600 comprising moving the elevator car 3 with the hoisting machine 5;5′ and the second hoisting roping 16. Said transporting 600 is illustrated in
[0150] After said installing 500, the hoisting machine 5;5′ installed in said second position II and said second roping 16 are left permanently at their places to form part of the final elevator.
[0151] In the preferred embodiment, in the method said first roping 6 is used in transporting passengers and/or goods with an elevator car only while the hoisting machine 5 is in said first position I. Correspondingly, said second roping 16 is used in transporting passengers and/or goods with an elevator car only while the hoisting machine 5:5′ is in said second position II. This use of each roping in only one hoisting machine position makes the roping 6;16 and other structures simple and lightweight. The method is quick to take into use and yet a jumping ability is achieved. Use of each roping 6;16 in only one hoisting machine position I;II is reflected by features of the preferred embodiment of the method, in particular in that said installing the first hoisting roping 6 comprises fixing the ends of the first roping to terminal devices 7, in particular such that neither of the opposite ends of individual ropes of the first hoisting roping 6 continues to a rope supply storage such as a rope reel. Thus, no excessive amount of rope need to be provided or stored for later feeding into the system, which might complicate structures and/or the method itself.
[0152] A second embodiment implementing the method described referring to
[0153] Generally preferably, each said first and second roping 6,16 comprises plurality of ropes. Generally preferably, all the ropes of said first roping 6 are installed to pass along the same route, and correspondingly all the ropes of said roping 16 are installed to pass along the same route.
[0154] Generally preferably, in the moving of each said transporting 200,600 the elevator car 3 is moved along and guided by one or more guide rail lines 4a.
[0155] Generally, the layout could also be different from what is shown in Figures.
[0156] As mentioned after said installing 500, the hoisting machine 5;5′ installed in said second position II and said second roping 16 are preferably left permanently at their places to form part of the final elevator. However, it is not necessary, since it is alternatively possible to continue the method with a further jump, including a further stopping, removing, installing and transporting correspondingly as aforementioned steps 200-600 the installation position being a third position higher than said second position and the roping to be installed being a third roping. In this case, the second position II would not be in a machine room.
[0157] Generally, although the successive order presented in
[0158] Generally, the method for constructing an elevator can comprise also additional steps not showed. Although, the method has been described advantageously containing a first and second roping, and first and second position respectively, the method could be continued e.g. with further jumps.
[0159]
[0160] In the preferred embodiment of Figures, said first guide 21 particularly comprises a first guide opening 210 for receiving a guide flange F of said guide rail line 4a; and said second guide 21 comprises a second guide opening 22o for receiving a guide flange F of said guide rail line 4a; and said guide channel structure 24 comprises a third guide opening 24o for receiving a guide flange F of said guide rail section 4a″ to be installed; wherein the vertical projections of said first, second and third guide opening 21o,22o and 24o overlap.
[0161] In the preferred embodiment of Figures, each said first, second and third guide opening 21o,22o and 24o is bordered on three lateral sides by a guide part 21a-21c;22a-22c;24a-24c, in particular by a guide face of a guide part 21a-21c;22a-22c;24a-24c.
[0162] In the preferred embodiment illustrated in Figures, the guide arrangement 40 further comprises a third guide 23 for engaging a vertical guide rail line 4a for taking lateral support from said guide rail line 4a, which third guide 23 is above the second guide 22 at a vertical distance thereof, and the vertically elongated guide opening 24o of elongated guide channel structure 24 extends between the second guide 22 and the third guide 23. This facilitates guidance of the guide rail section 4″ to be guided by the guide channel structure 24. Hereby, the guide channel structure can receive the guide rail section 4″ already prepositioned whereby the guide rail moves into its guidance gently and smoothly. Hereby, also the longitudinal channel structure can be protected from impacts, excessive loads and/or excessive cranking by the guide rail section 4″ being passed to its guidance. The lower two guides 21,22 can maintain the guide rail installation apparatus 13 stable even though the third guide 23 is higher than the upper end of the guide rail line 4a.
