Caterpillar’s new GC Series of single-drum vibratory soil compactors is available in North America

Caterpillar introduced its new GC Series, a line of single drum vibratory soil compactors, to North American markets this week.

The 84-inch machines, according to the manufacturer, were designed with high static linear load and more weight at the drum for better compaction performance, simple operation, high reliability and low cost-per-house performance.

The series’ new machines are made for jobsites that relate to road building, site preparation, large residential construction, large earth fill and agriculture, Caterpillar said.

Included in the series are both smooth (CS) and padfoot (CP) drum models: the 10-ton-class CS10 GC, the 11-ton CS11 GC and CP11 GC, and the 12-ton CS12 GC and CP12 GC.

The GC Series compactors, all with a low height of 9.8 feet, run on the 120.7 hp (90 kW) Cat C2.6 diesel engine, which meets the EPA’s Tier 4 Final and the EU’s Stage V emission standards, and the new models also have standard Eco-Mode operation that reduces engine speed to 2,000 rpm to deliver up to 10% fuel savings over operation at high idle.

Cat’s new line of compactors feature gradeability up to 55% for 10- and 11-ton models and up to 50% for 12-ton models thanks to their single propel pump with limited slip differential rear axle.

According to the company, the GC compactors feature the Cat-exclusive pod-style vibration system, which estimates a three-year, 3,000-hour service interval for reliable operation.

With simplified controls and digital readouts, the GC Series is tailored for easy operation, Caterpillar said, and the machines offer improved operator platform ingress/egress with angled steps, anti-skid entrance and handrails.

Cat’s vibratory soil compactor announcement comes a week after the manufacturer updated its cold planer models.
