Caterpillar continues to roll out its next generation of mini hydraulic excavators. The company showed off its new six-ton Cat 306 CR this week at the International Construction and Utility Equipment Exposition (ICUEE) in Louisville, Ky.

Marking the company’s entry into the six-ton class — previously it’s offered a 5.5-ton machine — the new model incorporates the features Caterpillar has rolled out on its other next-gen excavators, including the Cat Stick Steer system, LCD monitor, a more spacious cab and an improved fuel-efficient engine.

“Offering big performance features in a mini excavator, the new Cat 306 CR delivers class-leading lift performance of up to 7,839 pounds (3 555 kilogram) at a 9.8-foot (3-metre) radius,” the company said in a release. “Enhanced uphill swing torque and increased cycle times provide greater productivity and efficiency.”

The 306 CR is equipped with a Cat C2.4 turbo diesel engine rated at 55.9 net horsepower (41.7 kW). It meets Tier 4 Final/Stage V emission standards and includes features such as automatic engine idle and shutdown features help to save on fuel consumption.

Customers can choose between a sealed, pressurized cab or a canopy — which will become available next year. The cab option translates to a maximum operating weight of 15,821 pounds (7 175-kilograms).

Built with a swing boom, the mini excavator offers 58-inch (1 475-millimetre) tail swing with counterweight for working close to obstructions. The long stick option gives operators a max dig depth of 162 inches (4,110 millimetres).

Meanwhile, three blade options are available for the 306 CR. It comes in straight blade, angled blade and extra tool carrier (XTC) configurations.
