Master track chain connection for crawler tractors

摘要

A master track chain connection for use on track chains of crawler tractors is disclosed. The master connection includes apparatus for independently securing the track shoe to the split master link thereof and for retaining or clamping the half-links of the split master links together. Separating the track shoe retention function from the half-link clamping function maintains clamping integrity in the event of bolt-loosening as the result of load induced slippage of the track shoe relative the link. The apparatus includes a first bolt threaded into a first threaded aperture for solely fastening the track shoe to the link and a second bolt threaded into a second threaded aperture for solely retaining the half-links together. A third bolt is preferably provided for jointly securing the track shoe to the link and for clamping the half-links together.
