Abstract
A lift installation provided with a vertically moveable lift cage having an entrance. The lift cage is rotatably connected to a supporting structure adapted to rotatably couple to a helical guide formed into or connected to the shaft wall. The shaft structure rotates relative to the shaft wall causing the support structure, and thus the lift cage, to move vertically. The lift cage is rotatable about the vertical axis such that the entrance can be rotated with respect to the shaft wall.
