Komatsu PC490LCi Underwater Wall Grinding


This Komatsu Construction 490LCi is grinding a wall, underwater, in a barge lock. In years past, this work would have required draining the lock. An expensive and time consuming process.


With the latest Komatsu Smart Construction tech, a Quantum model and great dealer support this contractor made it look easy. This video is supposed to be boring.


The contractor completed this USACE project at a reduced cost and well ahead of river opening in just a few days.
