  • Track supporting roller apparatus
    Patent number: 5494125
    Abstract: A track supporting roller apparatus supports the articulated track chain of an undercarriage assembly of a track-type work machine. Vibrations and shock loads are generated to a track-type work machine when load bearing track rollers contact the articulated joints of the track chain and the born load is not picked up by an adjacent track roller. The subject roller apparatus has track rollers spaced to support the track chain and prevent the introduction of vibrations and shock loads.
