Most Komatsu PC75UU-1 and UU-2 machines are Gray Market Excavators. There have been a number of issues with rubber tracks not fitting correctly, fitting but falling off on a regular basis.
VIQAN worked with a company near Seattle WA experimenting with installing steel tracks with bolt on rubber pads as an option to replace rubber tracks. The result? Excellent! No more issues with tracks falling off, skipping etc.
The upside to switching to steel tracks with bolt on rubber pads? 1. Money saved on not having to crowbar derailed tracks. 2. Money saved on broken/split tracks. 3. Longer lasting than rubber!
