The new Cat 306 CR Mini Hydraulic Excavator marks Caterpillar’s entry in the 6-ton class offering. The new mini excavator features heavy-duty main structures, a fuel-efficient engine, load-sensing hydraulics, spacious cab, and exclusive Cat Stick Steer system. Standard exclusive features include stick steer and a new LCD monitor.
With its long stick option, the 306 CR delivers a maximum dig depth of 162 inches and 15,821-lb. maximum operating weight when equipped with the sealed and pressurized cab. A canopy alternative to the pressurized cab will be available for customers in 2020. Built with a swing boom, this mini excavator’s compact radius design provides a low, 58-inch tail swing with counterweight for working close to obstructions.
The excavator delivers class-leading lift performance of up to 7,839 lbs. at a 9.8-foot radius. Enhanced uphill swing torque and increased cycle times provide greater productivity and efficiency.
The machine’s fuel-saving, load-sensing hydraulic system with an electronically controlled variable-displacement piston pump generates 40 gal/min hydraulic oil flow. It offers the hydraulic capacity for increased travel performance and higher digging forces than competitive units.
High flow rate of 24 gal/min to the auxiliary circuit enables operation of demanding hydromechanical attachments. Complete with quick-disconnect lines, the standard auxiliary hydraulic system provides one-way, two-way, and continuous flow.
The Cat C2.4 turbo diesel engine rated at 55.9 net hp powers the mini excavator and meets U.S. EPA Tier 4 Final emission standards. Automatic engine idle and shutdown features help to save on fuel consumption.
