Abstract
The apparatus includes a positioning unit and an alignment unit. The positioning unit extends across the elevator shaft in a second direction and comprises at each end a first attachment mechanism movable in the second direction for supporting the positioning unit on opposite wall structures in the elevator shaft. The alignment unit extends across the elevator shaft in the second direction and is supported with support parts on each end portion of the positioning unit. Each end portion of the alignment unit is individually movable in relation to the positioning unit in a third direction perpendicular to the second direction. The alignment unit includes further at each end a second attachment mechanism movable in the second direction for supporting the alignment unit on opposite guide rails in the shaft. The second attachment mechanism includes a gripper for gripping on the guide rail.
