The sheave includes a main shaft which is hollowed partially adjacent to one end of the same to define a recess and which has a through hole formed in an external surface to communicate the recess and an exterior of the main shaft. An enclosed casing is fixed in the recess and has a circular plate that is disposed opposite to a bottom of the recess. The circular plate has a pressure gauge communicated with an interior of the enclosed casing, a plurality of coupling members and a release valve to release pressure from within the enclosed casing to an exterior of the enclosed casing.
