Abstract:
A crawler has a track tensioning system. The crawler includes a crawler frame having a bottom; at least one drive tumbler supported on the frame; a track made of a plurality of connected track shoes and is wrapped around the drive tumbler so that a plurality of the shoes are in contact with the drive tumbler. The track tensioning system, mounted to the frame, includes a roller engaging the inside surface of the track; and a roller positioning structure attached to the frame that can raise the roller relative to the bottom of the frame to thereby increase the tension of the track.
