Overview
On a Bachy job forming a stabilised ground wall around an open pit, the trencher's shoes were wearing out rapidly, causing downtime and constant change-outs. After trials with wear blocks and manganese strips, I specified carbide rock teeth and side cutters.
Scope & Methods
- Failure analysis of shoe wear patterns and operating conditions.
- Evaluated wear blocks and manganese strip options; documented results.
- Implemented carbide rock teeth and side cutters; adjusted fit-up.
- Monitored performance and documented wear-life.
Outcomes
- ~5x shoe life vs. baseline.
- Job completed on a single set; eliminated hourly replacements.
- Reduced downtime and lower consumable cost.
