Abstract

A method of constructing an elevator, the elevator including a hoistway, an elevator car, a first movable support structure in the hoistway above the elevator car, for supporting the elevator car with a roping, and a roof structure, separate from the movable support structure, in the hoistway above the support structure, where the elevator car is used for transporting passengers and/or goods, and thereafter the first movable support structure is lifted higher in the hoistway, and thereafter the elevator car is used again for transporting passengers and/or goods. The method includes lifting the roof structure higher in the hoistway so as to make more room below the roof structure, the roof structure being a movable roof structure, and in that the movable roof structure is lifted in the hoistway taking support for the lift from a second movable support structure mounted in the hoistway above the roof structure.

First claim

The invention claimed is:

1. A method in constructing an elevator, in which the elevator includes at least one elevator car movable in a hoistway, a first movable support structure, a separately movable roof structure, and a lifting arrangement, the first movable support structure being separate from the at least one elevator car, in the hoistway above the at least one elevator car, the first movable support structure being configured to support said at least one elevator car, the separately movable roof structure being, separate from the first movable support structure, in the hoistway above the first movable support structure, and the lifting arrangement including a second movable support structure mounted in the hoistway at a first mounting position above the separately movable roof structure, the method comprising:
providing the at least one elevator car to be used for transporting passengers and/or goods;
lifting the first movable support structure in the hoistway;
lifting the separately movable roof structure higher in the hoistway to create greater space between the separately movable roof structure and the first movable support structure; and
manually moving the lifting arrangement by manually moving the second movable support structure upwardly in the hoistway to a second mounting position above the first mounting position while the separately movable roof structure is supported by walls of the hoistway.

2. The method according to claim 1 , wherein the lifting arrangement includes a rope and a lifting device.

3. The method according to claim 2 , wherein the manually moving the lifting arrangement further comprises:
manually lifting the lifting arrangement in parts by first manually moving the second movable support structure to the second mounting position by a person, and subsequently lifting the lifting the lifting device by attaching the rope of the lifting arrangement to a pulling rope and pulling the pulling rope from the second mounting position.

4. The method according to claim 3 , wherein the pulling rope is set to extend vertically in the hoistway, by dropping the pulling rope into the hoistway from the second mounting position, so as to connect the parts of the lifting arrangement.

5. The method according to claim 1 , wherein
the elevator includes a third movable support structure between said first movable support structure and said second movable support structure, and
the third movable support structure is lifted higher in the hoistway before lifting the first movable support structure higher in the hoistway.

6. The method according to claim 1 , further comprising:
lowering the lifting arrangement to a platform of the separately movable roof structure prior to lifting the separately movable roof structure.

7. An elevator arrangement, comprising:
at least one elevator car movable in a hoistway;
a first movable support structure, separate from the at least one elevator car, in the hoistway above the at least one elevator car, for supporting the at least one elevator car;
a separately movable roof structure, separate from the first movable support structure, in the hoistway above the first movable support structure; and
a second movable support structure mounted in the hoistway at a first mounting position above the separately movable roof structure for lifting the separately movable roof structure higher in the hoistway, the second movable support structure being manually movable upwardly in the hoistway to a second mounting position above the first mounting position while the separately movable roof structure is supported by walls of the hoistway.

8. The elevator arrangement according to claim 7 , wherein the second movable support structure is movable by a person.

9. The elevator arrangement according to claim 8 , wherein the second movable support structure is made up of plural parts.

10. The elevator arrangement according to claim 7 , wherein
a lifting arrangement is configured to lift the separately movable roof structure in the hoistway, the lifting arrangement including a rope and a lifting device, the lifting device being configured to connect to the separately movable roof structure.

11. The elevator arrangement according to claim 10 , further comprising:
a power supply to lift the lifting device positioned as part of the separately movable roof structure, the power supply being an electrical power supply line and the lifting device being an electrical lifting device.

12. The elevator arrangement according to claim 7 , wherein the separately movable roof structure includes a water-proof membrane.

13. The elevator arrangement according to claim 7 , wherein the separately movable roof structure includes a platform on which a person can walk and a water-proof roof part above the platform.

14. An elevator arrangement, comprising
at least one elevator car movable in a hoistway;
a first movable support structure, separate from the at least one elevator car, in the hoistway above the at least one elevator car, for supporting the at least one elevator car;
a separately movable roof structure, separate from the first movable support structure, in the hoistway above the first movable support structure; and
a second movable support structure mounted in the hoistway above the separately movable roof structure for lifting the separately movable roof structure higher in the hoistway, wherein
the second movable support structure is movable by a person.
