In this paper, the new approaches to reliability assessment on the weir-gate facilities are shown as a substitute for maintenance operation with gate opening/closing. One is inspection of the hoist by means of slack wire rope operation, and the other is axial relative displacement measurement of the main roller bearing. The measuring results show that relative displacement of the main roller bearing arises from temperature difference between water and gate. The former happens on a long time, and the latter is caused by between day and night.
