  • the guiding devices 45 are already aligned before the lower ends of the guide shoe carriers 41 have reached the upper ends of the car guide rails 6 already installed.
  • the elevator unit can then be lowered further without the car guide rails already fixed to the elevator shaft walls colliding with the guide shoe carriers 41 or the supports present thereon for fastening the guide shoes.
  • the guide devices 45 fixed in place in the elevator shaft 2 interact with the associated alignment elements 5 mounted on the elevator unit 10 in such a way that the at least one elevator unit hanging on the cable of the lifting device 25 remains in the aligned position.
  • the upper and lower guide shoes 35.1, 35.2 and the respective associated car guide rails 6 can be fitted into one another, and the guide shoes 35.1, 35.2 can be mounted and fixed - for example by a fitter - on the guide shoe carriers 41 of the machine platform 10.1.
  • FIG. 5 shows a fourth embodiment of the method, in which also an outside of the Elevator shaft 2 preassembled, in the present example formed by the machine platform 10.1 elevator unit 10 is lowered by means of the construction crane 25 in the elevator shaft 2.
  • the upper and lower guide shoes 35.1, 35.2 are already mounted on the elevator unit 10 when the machine platform is lowered into the elevator shaft.
  • a guide device 45 with upwardly opening guide channel 45.1 is fixedly attached to two opposite elevator shaft walls 2.2.
  • an alignment rail 7, which is aligned in the vertical direction with the associated guide device 45 and serves as an alignment element 5, is mounted.
  • the guide devices 45 and the alignment rails 7 are positioned relative to one another in the vertical direction such that when the machine platform 10.1 is lowered into the elevator shaft 2, the lower ends of the alignment rails are already aligned and guided by the guide devices before the lower guide shoes 35.2 of the machine platform have reached the momentarily upper ends of the car guide rails 6.
  • the machine platform 10.1 which is aligned by the interaction of the guide devices 45 with the alignment rails 7, is lowered further, the lower guide shoes 35.2 of the machine platform first come into engagement with the cabin guide rails 6—preferably slightly chamfered at their upper ends. After further lowering of the aligned machine platform 10.1, the upper guide shoes 35.1 also come into engagement with the cabin guide rails 6.
  • additional guide devices 48 can be arranged on the guide shoe supports 41 of the machine platform 10.1 below the mentioned upper guide shoes 35.1.
  • Such additional guide devices 48 which are difficult to dismantle in the arrangement shown, are preferably made of plastics or hardwood or are formed by welded parts integrated into the guide shoe carrier 41.
  • FIGS. 5A and 5B show in an elevation and in a side elevation shown in section upper end of a guide shoe carrier 41 with an upper guide shoe 35.1 mounted on the latter and with the above-mentioned additional guide device 48. From these representations it can be seen how the additional guide device 48 helps, when lowering the machine platform 10.1 forming the elevator unit, the upper guide shoes 35.1 mounted on this and the upper ends of the - in Figure 5B shown in phantom - to lead car guide rails 6 into each other.
  • FIG 1 Elevator system 1 shows a slightly modified embodiment of FIG 1 Elevator system 1 shown, in which the usable lifting height of the elevator car 10.2 is also adapted to an increasing height of a building or an elevator shaft 2 that is in its construction phase.
  • the machine platform 10.1 which carries the elevator car 10.2 and the counterweight 8 is not lifted from time to time with the help of a construction crane, but this lifting of the machine platform 10.1 is carried out by means of a lifting platform 10.3 which is equipped with a lifting device 60 and forms a further elevator unit 10.
  • the advantage of this embodiment is that for the lifting of the machine platform 10.1 to be carried out from time to time, no construction crane with sufficient lifting power to lift the machine platform has to be available. For the lifting of the much lighter lifting platform 10.3 required before each lifting of the machine platform 10.1, a light lifting device (in 6 Not shown).
  • the light lifting device and the associated support element must also be placed correspondingly further up in the elevator shaft. If, at the given point in time when the lifting platform is being raised, no construction crane is available for lifting the light-weight lifting device, both the support element and the light-weight lifting device can be transported to a higher level via the stairwell, for example.
  • the lifting platform 10.3 described above which can be raised in the elevator shaft 2, is also guided on the car guide rails 6 via guide shoes 35 mounted on the lifting platform.
  • the lifting platform 10.3 is also introduced into the elevator shaft 2 with the aid of a construction crane in the pre-assembled state, lowered to a planned level in the elevator shaft and supported there via support elements 30 in the elevator shaft.
  • the different variants of the alignment process and the guide devices and alignment elements used are the same as those described above in connection with the Figures 2 - 5 are described.
  • At least the guide devices 45 attached to the elevator shaft walls 2.2 or to the elevator units 10 - but preferably also the alignment rails 7 serving as alignment elements 5 and fixed to the elevator units 10 - are each dismantled after the elevator units have been lowered into the elevator shaft and the guide shoes 35.1, 35.2 of the elevator units have been brought into engagement with the car guide rails 6.
  • the dismantled elements are reused when lowering other elevator units in the same building or when lowering elevator units in other elevator systems.
  • At least the guide elements 47.1-47.3 of the guide devices 45 are made of an impact-damping and/or friction-reducing material, or at least the guide surfaces 47.1.1-47.1.3 of the guide elements 47.1-47.3 are coated with such a material. This ensures that when the at least one elevator unit 10 is lowered into the elevator shaft 2 and the alignment process takes place, the alignment effect is improved and the alignment elements 5 formed by car guide rails 6 or alignment rails 7 and interacting with the guide devices 45 are not damaged.
