Equipment Overview
The Cat 18 is a mining-class motor grader built for haul road construction and maintenance, part of Caterpillar’s mining grader range alongside the 14, 16 and 24. It runs a 5.5 m (18 ft) moldboard as standard, weighs around 33,713 kg typically equipped, and produces up to 266 kW (357 hp), suited to mine haul roads paired with large haul trucks.
Power comes from a Cat C13 engine, rated at 227 kW (304 hp) in first gear and rising to 266 kW (357 hp) through the VHP range, meeting Tier 3/Stage IIIA equivalent emissions. An 8-speed power shift transmission drives the tandem rear axle, and the wider moldboard increases coverage per pass compared with a 16 ft blade, while still keeping the windrow clear of the tyres.
