Abstract

Method in the manufacture of an elevator, in which method the parts of a platform, more particularly its support structure, are used for forming the structure that supports the machinery of the final machine room of the elevator, which platform has earlier been in its position in a position disposed lower in the elevator hoistway, and which platform was used in the aforementioned lower disposed position for supporting the machinery.

First claim

The invention claimed is:

1. A method for installation of an elevator, the method comprising:
moving, without use of a worksite crane, a first platform of the elevator and a separate first support structure by a plurality of jump-lifts in progressive steps upwards in an elevator hoistway, the first platform including at least machinery for moving an elevator car during the installation of the elevator; and
utilizing at least a movable support structure of the first platform to form a final support structure supporting the machinery in a final machine room of the elevator after completion of a final jump-lift among the plurality of jump-lifts, wherein
the first platform is positioned below the separate first support structure in the elevator hoistway,
the separate first support structure supports the first platform during the installation of the elevator,
the separate first support structure is positioned below a separate second support structure in the elevator hoistway, and
the separate second support structure supports the separate first support structure via a hoisting device and a rope or cable during the installation of the elevator.

2. The method according to claim 1 , further comprising:
transferring, via the final jump-lift, the machinery from a position in the elevator hoistway into a space reserved for the final machine room.

3. The method according to claim 2 , wherein the transferring comprises:
lifting the movable support structure through an aperture leading into the space reserved for the final machine room; and
lowering the movable support structure onto load-bearing structures of a building.

4. The method according to claim 3 , wherein the load-bearing structures include at least one of,
a part of a floor of the space reserved for the final machine room,
a third support structure supported on the floor, or
a wall structure of a top part of the elevator hoistway.

5. The method according to claim 3 , further comprising:
removing, prior to the lifting of the movable support structure, at least one of
at least a part of the hoisting device,
at least a part of a frame of the first platform supporting the machinery,
a working platform above the machinery,
buffers, or
the separate first support structure.

6. The method according to claim 2 , after transferring the machinery into the space reserved for the final machine room, the method further includes
supporting the first platform in position in the final machine room, wherein
in the final machine room, the machinery is at least partly supported by the movable support structure.

7. The method according to claim 2 , wherein:
the space reserved for the final machine room includes a floor; and
the space reserved for the final machine room is wider than the elevator hoistway in at least one lateral direction.

8. The method according to claim 1 , further comprising:
transferring, while being supported by the first platform, the machinery into a space reserved for the final machine room of the elevator by lifting the movable support structure through an aperture leading into the space while the movable support structure is in a contracted position;
extending the movable support structure into an extended position in which the movable support structure extends over load-bearing structures of a building; and
lowering the movable support structure onto the load-bearing structures of the building.

9. The method according to claim 8 , wherein after lowering the movable support structure onto the load-bearing structures of the building, the method further includes,
filling the aperture between the elevator hoistway and the space with casting material.

10. The method according to claim 9 , wherein the filling comprises:
casting the casting material onto a plate placed in the aperture, a top surface of the plate being below a top surface of a floor of the space reserved for the final machine room.

11. The method according to claim 9 , further comprising:
casting a platform having a top surface on substantially the same level as a top surface of a floor of the final machine room.

12. The method according to claim 8 , wherein, in the extended position, the movable support structure extends over a load-bearing structure of the building on at least two opposite sides of the aperture.

13. The method according to claim 1 , further comprising:
lifting the separate first support structure with the hoisting device, which takes a vertical support force needed for lifting from a structure of a space reserved for the final machine room of the elevator, such that the support force is taken from a position higher than a level of a top surface of a floor of the space reserved for the final machine room.

14. The method of claim 13 , wherein the vertical support force is taken from at least one of,
a roof of the space reserved for the final machine room,
walls of the space reserved for the final machine room, or
an additional support structure arranged in the space reserved for the final machine room, the additional support structure being supported by the floor of the space reserved for the final machine room.

15. The method according to claim 1 , further comprising:
utilizing the machinery to move the elevator car and serve passengers during the installation of the elevator and while the machinery is positioned lower in the elevator hoistway relative to the separate first support structure.

16. The method according to claim 1 , further comprising:
serving passengers using the elevator before reaching a final lifting height of the elevator; and
transferring the machinery into a space reserved for the final machine room of the elevator when the first platform reaches an upper part of the elevator hoistway, the space reserved for the final machine room of the elevator being an extension of the elevator hoistway, and being above the upper part of the elevator hoistway.

17. The method according to claim 1 , wherein the utilizing comprises:
forming the final support structure supporting the machinery in the final machine room of the elevator at least partly from the movable support structure of the first platform such that a space above the movable support structure is the final machine room, and the elevator hoistway is below the movable support structure.

18. The method according to claim 1 , further comprising:
supporting, after each of the plurality of jump-lifts, the first platform in position in the elevator hoistway by extending the movable support structure to rest on a top surface of a load-bearing structure of a building on at least two opposite sides of the elevator hoistway.

19. The method according to claim 1 , wherein the machinery used to move the elevator car during the installation of the elevator between the plurality of jump-lifts is used as the machinery for moving the elevator car of the elevator after installation of the elevator is complete.

20. The method according to claim 9 , wherein the filling comprises:
forming at least part of a roof structure of the elevator hoistway.

21. A method for installation of an elevator, the method comprising:
moving, without use of a worksite crane, a first platform of the elevator by a plurality of jump-lifts in progressive steps upwards in an elevator hoistway, the first platform including at least machinery for moving an elevator car during the installation of the elevator;
removing at least a part of a frame of the first platform, to decr
