    Abstract: 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.

    Abstract: The invention relates to a method of constructing an elevator comprising providing an elevator car in a hoistway, said elevator car comprising a cabin frame, and a temporary pulley beam detachably mounted on the cabin frame; mounting a hoisting machine in a first position which first position is at a first vertical level in the hoistway; suspending (first suspending) the elevator car with a hoisting roping from the hoisting machine via said temporary pulley beam; moving the elevator car in the hoistway with the hoisting machine while it is in said first position and suspended by the roping via said temporary pulley beam; mounting a hoisting machine in a second position which second position is at a second higher vertical level inside a machine room located above the hoistway; removing the temporary pulley beam from the elevator car, comprising detaching the temporary pulley beam from the cabin frame; suspending the car with a hoisting roping from the hoisting machine mounted in said second position via said cabin frame without said temporary pulley beam; moving the elevator car in the hoistway with the hoisting machine while it is in said second position and the car is suspended via said cabin frame without said temporary pulley beam. The invention also relates to an elevator arrangement for implementing the method.

    Abstract: The invention relates to a construction arrangement of an elevator, comprising a hoistway formed in a building, the hoistway comprising at least one hoistway opening leading in horizontal direction out from the hoistway, the opening being delimited by a lower edge structure and an upper edge structure; and a load in the hoistway lower than said opening; and a hoisting arrangement for hoisting said load, wherein said hoisting arrangement comprises a support structure mounted higher than said load; and a hoisting device; and at least one flexible tension member connected or at least connectable to said load; wherein the at least one flexible tension member is movable with said hoisting device in particular for thereby transmitting a hoisting force to said load to be hoisted. Said support structure comprises an anchoring beam structure comprising a lower end engaging the lower edge structure, and an upper end engaging the upper edge structure; and a support beam structure connected to the anchoring beam structure and protruding from the anchoring beam structure into the hoistway; and wherein said at least one flexible tension member hangs in the hoistway supported by the support beam structure. The invention also relates to a method implementing the construction arrangement.
