5 . The arrangement according to claim 1 , wherein the hoisting machine comprises a drive wheel positioned towards the structure of the hoistway which provides mounting structure for an adjacent one of the at least one car guide rail, or
wherein the hoisting machine comprises the drive wheel positioned towards the elevator car.
6 . The arrangement according to claim 1 , wherein the hoisting machine is placed on the at least one counterweight guide rail, when viewed in a horizontal direction,
and/or wherein
the hoisting machine is configured to be demounted from a first installation position in the hoistway and to be mounted to an upper second installation position in the hoistway, and
the second installation position is provided with second car guide rails and second counterweight guide rails forming continuing car guide rail lines and continuing counterweight guide rail lines to a bottom portion of the hoistway before said demounting.
7 . The arrangement according to claim 1 , wherein the hoisting machine is askew from the wall of the hoistway.
8 . The arrangement according to claim 1 , wherein the vertical projection of the hoisting machine is separate from the at least one car guide rail.
9 . A method for constructing an elevator comprising providing a construction arrangement according to claim 1 , and moving the hoisting machine from a first installation position to an upper second installation position in the hoistway, and mounting the hoisting machine between said at least one car guide rail and said at least one counterweight guide rail.
10 . The method according to claim 9 , wherein
additionally to the mounting of the hoisting machine to a mounting structure,
integrating a first rope fixing to the mounting structure to form an integrated first rope fixing for a plurality of hoisting ropes.
11 . The method according to claim 9 , wherein positioning a drive wheel comprised by the hoisting machine towards the structure of the hoistway which provides mounting structure for an adjacent one of the at least one car guide rail, or
