18M3 Motor Grader The new Cat 18M3 Motor Grader was designed to provide more power and greater coverage per pass compared to the Cat 16M3 .
Based on the popular 16M3 model , the new motor grader offers additional power and a wider moldboard to support small- and medium-size mining operations that run190-ton or smaller hauling trucks . The 18M3 is powered by a Cat C13 ACERT™ engine , which uses the Caterpillar Optimized Variable Horsepower ( VHP ) system , designed to deliver optimum power in each gear for the operating situation . The engine is available in three configurations to satisfy global emissions standards :
• U . S . EPA Tier 4 Final / EU Stage IV / Japan 2014 ( Tier 4 Final ) • Tier 3 / Stage IIIA / Japan 2006 ( Tier 3 ) equivalent • Tier 2 / Stage II / Japan 2001 ( Tier 2 ) equivalent
