Overview

The 18M3 builds on the success of the 16M and offers additional power, a wider moldboard and the possibility to use a more aggressive blade angle, making it an ideal fit for mining operations that run 172-tonne (190-ton) or smaller trucks. The 18M3 enhances operational efficiencies by increasing coverage and reducing the number of passes required to complete the width of the road in certain applications. The 18M3 includes features that provide large benefits on operating cost reduction, uptime & performance improvements as well as enhanced safety.
