Apparatus for alignment of an elevator guide rail

摘要

Example embodiments relate to an apparatus including a stationary first part, a movable second part, and a link arm mechanism connecting the first part and the second part. The first and the second link arm may be interconnected with a fifth articulated joint. First ends of the link arms may be connected with articulated joints movably on the first part. Second ends of the link arms may be connected with articulated joints on the second part. The second part may be moved with a first actuator in a first direction, with a second actuator in a third direction and with a third actuator in a fourth angular direction around the fourth articulated joint.
