New 18 Motor Grader in North Carolina

Back to

The 18 builds on the success of the 16 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 18 enhances operational efficiencies by increasing coverage and reducing the number of passes required to complete the width of the road in certain applications. The 18 includes features that provide large benefits on operating cost reduction, uptime, performance improvements, and enhanced safety.
