The apparatus (500) comprises a positioning unit (100) and an alignment unit (200). The positioning unit extends across the elevator shaft (20) in a second direction and comprises at each end first attachment means (140, 150) movable in the second direction for supporting the positioning unit (100) on opposite wall structures (21) in the elevator shaft (20). The alignment unit (200) extends across the elevator shaft (20) in the second direction and is supported with support parts (260, 270) on each end portion of the positioning unit (100). Each end portion of the alignment unit (200) is individually movable in relation to the positioning unit (100) in a third direction perpendicular to the second direction. The alignment unit (200) comprises further at each end second attachment means (240, 250) movable in the second direction for supporting the alignment unit (200) on opposite guide rails (50) in the shaft (20). The second attachment means (240, 250) comprises gripping means (245, 255) for gripping on the guide rail (50). |
