A method for constructing an elevator into a destination location from a plurality of prefabricated elevator modules includes fabricating a plurality of elevator modules, in particular at a location apart from said destination location. The fabricating includes providing one or more module frames having a longitudinal axis; positioning one or more of the module frames in horizontally oriented position, wherein in the horizontally oriented position the longitudinal axis is horizontal; and while the one or more module frames are in the horizontal position, performing installation work on said one or more module frames. The method includes arranging the modules into the destination location on top of each other such that said modules are in a vertically oriented position.

Method for constructing an elevator

The invention relates to a method for constructing an elevator, comprising piling plurality of prefabricated modules on top of each other, such that the hoistway spaces of the prefabricated modules are vertically aligned forming a continuous vertically elongated hoistway where the elevator car and the counterweight can be fitted to move; and arranging the elevator car and the counterweight to be vertically movable in the hoistway. The plurality of prefabricated hoistway modules comprise a prefabricated top module comprising a machinery for driving a hoisting roping, and the prefabricated top module comprises one or more car guide rail sections and one or more counterweight guide rail sections, wherein the machinery for driving a hoisting roping is mounted on a support structure, which is mounted on plurality of said guide rail sections of the prefabricated top module. The invention also relates to an elevator obtained with the method.

Method for constructing elevator and such elevator

The invention relates to an elevator, comprising a hoistway with a plurality of hoistway sections attached to each other to provide a hoistway with a hoistway space, an elevator car arranged in the hoistway space to be vertically movable in the hoistway space between door openings at landings of a building, and doors at the door openings. In order to avoid problems caused by a mutual change of height of a hoistway and a building, a sensor provides to a control system a signal indicating a level difference between a first reference point of the hoistway and a second reference point of the building.
