The two crane girders are afterwards laid out next to one another and aligned.

    Lay the profile rail sections on a raised base. The profile rail sections should protrude on one side far enough so that the trolley can later be inserted from there.

    Lay the HB profile rails for the crane girders exactly parallel to one another.

    Arrange the HB profile rails so that they have the LSK distance (track gauge 700 mm or 850 mm) to one another.
