The plumbing jig (22) is mounted in the upper part of the elevator shaft from the top floor (11), plumb lines (43) are attached to the plumbing jig from the top floor (11) and, using the plumb lines (43) attached to the plumbing jig (22), the shaft equipment (28) is positioned, whereupon the shaft equipment (28) is fixed in place. The apparatus includes supporting elements (41) that can be fixed to the elevator shaft, a plumbing jig (22) that can be attached to the supporting elements (41) and mounted substantially from the top floor (11), and plumb lines (43) that can be suspended from the plumbing jig (22) and extend into the elevator shaft (2) below the plumbing jig.
