Abstract

See full text

An elevator shaft door sill installation apparatus includes first and second assembly jig parts mounted at gage guide rails and a laser arranged at one of the parts for aligning the sill in the vertical direction. The alignment of the sill in the horizontal direction is undertaken with a line set including at least two lines, a first line having a first run extending from the first part to a first sill corner and from there by a second run to the second part, and a second line extending from the second part to a second sill corner. If the lines are tightened and a marking between the first and second runs is at the first corner of the sill, the sill is aligned in the horizontal direction.
