In this paper,by studying the temperature deformation rule of the ring crane beam in nuclear power plant reactor,together with the feature that the bolt hole's positioning for ring crane rail beam is influenced only by the angular deviation,and reasonable distribution of all measurement tolerances,the above-mentioned method had been verified by u-sing the redundant measurement method,which made sure that the bolt hole's positioning angular deviation was limited within 2 mm.Moreover,exact match of the various 180 bolt holes on the beam with those on the bracket was realized, which also ensured that the installation of the ring crane beam in the nuclear power plant reactor was completed success-ful in one step.
