Equipment Overview
The Cat 12 is a motor grader built for road construction, maintenance and general civil grading, part of Caterpillar’s grader line-up alongside the 120, 140 and 160. It runs a 3.7 m (12 ft) moldboard as standard, weighs around 18,400 kg typically equipped, and produces up to 159 kW (213 hp), suited to council road work, subdivision earthworks and general construction sites across Australia.
Power comes from a Cat C7 ACERT engine, rated at 136 kW (183 hp) in first gear and rising to 159 kW (213 hp) through the VHP Plus range, meeting Tier 3/Stage IIIA equivalent emissions. An 8-speed power shift transmission drives the tandem rear axle, and load-sensing hydraulics keep implement response consistent. Automatic articulation return-to-centre and a hydraulic demand fan are standard, helping keep operator workload down over a long shift.
