You consider the safety of your workers a top priority, and we're doing our best to help you meet your safety goals. Caterpillar considers the safety of everyone in, on or around Cat equipment when developing new products or enhancing safety features for existing products. The 18M3 has numerous safety features such as but not limited to:
Access to Tandem
Light Emitting Diode (LED) Enclosure Service Lights
Seat Belt Indication
Fire Suppression Ready System
Rearview Camera
Access Platform – optional
Service Access Platform – optional
Your local Cat dealer is committed to helping you succeed, by ensuring you have the right machine for the job, making parts available, and providing you with versatile work tools.
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.
