Abstract

A material transport and installation arrangement comprising a first working platform system in an elevator shaft for reaching a first installation height; and a first material hoisting system for moving elevator components vertically in the elevator shaft is disclosed. The arrangement is characterized in that it comprises a second working platform system in the elevator shaft for reaching a second installation height, the second working platform system comprising a second platform hoist, second platform roping and a vertically moveable second working platform, the second working platform being below the first working platform; and a second material hoisting system for moving elevator components vertically in the elevator shaft, the second material hoisting system comprising a second material hoist, second material roping and a second material holder. Further, a method for parallel transport and installation of elevator components is disclosed.

First claim

1 . A transport and installation arrangement for parallel transport and installation of elevator components, the arrangement comprising
a first working platform system in an elevator shaft for reaching a first installation height, the first working platform system comprising a first platform hoist, first platform roping and a vertically moveable first working platform; and a first material hoisting system for moving elevator components vertically in the elevator shaft, the first material hoisting system comprising a first material hoist, first material roping and a first material holder, the first material holder being moveable along at least one counterweight guide rail, wherein the arrangement further comprises a second working platform system in the elevator shaft for reaching a second installation height, the second working platform system comprising a second platform hoist, second platform roping and a vertically moveable second working platform, the second working platform being below the first working platform; a second material hoisting system for moving elevator components vertically in the elevator shaft, the second material hoisting system comprising a second material hoist, second material roping and a second material holder.

2 . The transport and installation arrangement according to claim 1 , wherein the first working platform system and/or the second working platform system are mounted to the top part of the elevator shaft, or wherein the first working platform system and/or the second working platform system are mounted to one or more lifting beams installed above the first and second installation heights.

3 . The transport and installation arrangement according to claim 1 , wherein the second platform roping runs through the first working platform.

4 . The transport and installation arrangement according to claim 3 , wherein the first working platform comprises a protective collar surrounding the second platform roping.

5 . The transport and installation arrangement according to claim 1 , wherein the first working platform system is mounted to the top part of the elevator shaft, or the first working platform system is mounted to one or more lifting beams installed above the first and second installation heights; and the second working platform system is mounted on the first working platform.

6 . The transport and installation arrangement according to claim 1 , wherein the first working platform system and/or the second working platform system are moveable along elevator car guide rails.

7 . The transport and installation arrangement according to claim 1 , wherein the second material hoisting system is positioned laterally to the first working platform and the second working platform for moving elevator components vertically in the elevator shaft independently of the height at which the first working platform and the second working platform are.

8 . The transport and installation arrangement according to claim 1 , wherein the second material hoisting system is suspended in front of the vertical center-line of elevator landing entrances.

9 . The transport and installation arrangement according to claim 1 , wherein the first material hoisting system is configured to transport guide rail sections and the second material hoisting system is configured to transport pre-assembled landing door arrangements.

10 . The transport and installation arrangement according to claim 1 , wherein the first working platform comprises a protection extension extending in a horizontal direction around the first working platform to prevent accidental falling of items from the first working platform.

11 . The transport and installation arrangement according to claim 1 , wherein the first working platform and/or the second working platform comprise a limit switch for maintaining a predetermined minimum distance between the first working platform and the second working platform.

12 . The transport and installation arrangement according to claim 1 , wherein the first working platform or the second working platform comprises an elevator car sling or an elevator car.

13 . The transport and installation arrangement according to claim 1 , wherein the first working platform is usable for installing elevator car guide rails and counterweight guide rails and the second working platform is usable for installing pre-assembled landing door arrangements.

14 . The transport and installation arrangement according to claim 1 , wherein at least one first or second installation height is at the height of at least 50 meters form the bottom of the elevators shaft; or wherein at least one first installation height is at the height of at least 100 meters form the bottom of the elevators shaft; or wherein at least one first installation height is at the height of at least 150 meters form the bottom of the elevators shaft; or wherein at least one first installation height is at the height of at least 250 meters form the bottom of the elevators shaft.

15 . A method for parallel transport and installation of elevator components comprising simultaneously or in any order the steps of
a) assembling a first working platform system; b) assembling a first material hoisting system; c) assembling a second working platform system; and d) assembling a second material hoisting system;
wherein the method comprises the further step of
e) transporting elevator components vertically in the elevator shaft by the first material hoisting system and the second material hoisting system and installing the elevator components.

16 . The method according to claim 15 , wherein the method further comprises the step of installing a length of elevator car guide rails and/or a length of counterweight guide rails at any point before step e).

17 . The method according to claim 15 , wherein the elevator components are transported in parallel by the first material hoisting system and the second material hoisting system and/or the elevator car components are installed in parallel from the first working platform and the second working platform.

18 . The method according to any of claims 15 , wherein the first working platform is used for installing elevator car guide rails and counterweight guide rails and the second working platform is used for installing pre-assembled landing door arrangements.

19 . Use of the material transport and installation arrangement according to claim 1 .
