The invention relates to a movable machine room comprising a support platform of a hoisting machine, the support platform comprising one or more releasable mounting mechanisms for releasably mounting the moveable machine room in a hoistway, and a hoisting machine mounted on the support platform; a working platform on top of the support platform, preferably forming a roof of the moveable machine room and/or comprising handrails; and at least one support structure supported by which the working platform rests on the support platform; and wherein each said support structure is selectively actuatable to expand in vertical direction for hoisting the working platform higher above the support platform taking reaction force from the support platform, or to contract in vertical direction for lowering the working platform back towards the support platform. The invention relates to an arrangement and a method implementing the movable machine room.

Movable machine room, elevator arrangement and method for constructing elevator

An elevator arrangement having an elevator includes an elevator car having a floor and a roof. The elevator car is provided with one or more extension spaces which are arranged to extend the height of the elevator car during construction time use.

Elevator arrangement

The invention relates to a method for constructing an elevator comprising constructing a movable machine room in the bottom end of a hoistway formed in a building under construction; and thereafter hoisting the movable machine room; and constructing an elevator car in the bottom end of the hoistway below the movable machine room; and providing a counterweight in the bottom end of the hoistway below the movable machine room; connecting the elevator car and the counterweight with a suspension roping; and thereafter hoisting the movable machine room to a first transport position; and thereafter mounting the movable machine room to the first transport position in the hoistway vertically supported on stationary structures; and thereafter using the elevator car for transporting passengers and/or goods below the movable machine room while the machine room is mounted in said first transport position and the elevator car and the counterweight hang suspended from the machine room by the hoisting roping; and thereafter hoisting the movable machine room upwards to a second transport position; wherein the second transport position is higher than said first transport position; and thereafter mounting the movable machine room to the second transport position in the hoistway vertically supported on stationary structures; and thereafter using the elevator car for transporting passengers and/or goods below the movable machine room while the movable machine room is mounted in said second position.
