Abstract

See full text

Method to properly discriminate fitting pressure of articulated track links. Loading pressure in the ram of a track press is compared with both the lower and upper limit pressure values which are prescribed with reference to the range of fitting pressure specified for the links. Fitting of a link is determined acceptable when a sum of the press loading time is longer than a predetermined value while press pressure is maintained within the range between both the lower and upper pressure values; whereas it is determined unacceptable when the sum of press loading time is shorter than the predetermined one or when time in which press pressure exceeds the upper limit pressure is longer than a predetermined time.
