Publication number: 20220219770Abstract: A replaceable guide rail for a crawler includes a base that has a flange. The replaceable guide rail further includes a hole extending laterally through the flange that is configured to receive a fastener to secure a portion of the crawler to the flange, a guide member extending along the centerline and being configured to contact a track portion of the crawler and be worn down during movement of the track portion over the guide member, and a wear indicator positioned in the guide member configured to indicate whether the guide rail is in condition for replacement. The guide member has a thickness that is reduced as the guide member is worn down. The wear indicator is covered while the thickness is in a first range of thickness, and the wear indicator is exposed while the thickness is in a second range of thickness.Type: ApplicationFiled: January 13, 2022Publication date: July 14, 2022Inventors: Ethan Pedretti, Pat Sterling
