Case: Full-sized excavator has increased fuel efficiency
Tina Grady Barbaccia | April 23, 2012
Case Construction Equipment launched its new CX210C full-sized excavator at the World of Concrete in January. The company says the excavator achieves 160 net horsepower using Tier 4 Interim-certified cooled exhaust gas recirculation technology that burns cleaner while delivering superior horsepower. Boom Economy Control lowers engine RPMs during the boom down and swing operation; the Auto Economy Control lowers RPMs when the joysticks are inactive. Swing Relief Control technology manages the hydraulic power allotted at the start of the swing operation, and Spool Stroke Control creates automatic pressure adjustment during digging operations.
A new narrow undercarriage version, measuring 8 feet, 6 inches in width, is available for easier transport. The machine is said to offer 10-percent fuel economy gains, 3-percent cycle-time reductions, and 7-percent lift capacity increases. Additional features include a 440-pound increase in operating weight to 47,800 pounds; a bucket digging force of 34,171 pounds; arm digging force of 24,729 pounds; and a maximum dig depth of 21 feet, 10 inches. Standard bucket sizes range from 0.65 to 1.53 cubic yards.
The spacious cab offers 7 percent more overall space and 25 percent more airflow. The machine is said to offer 19 percent better visibility from the driver’s seat compared to previous models. A rear-view camera and optional side cameras feed video to a 7-inch LED monitor for additional safety. Vibration refinement on the cab’s reinforced tubular structure reduces noise levels to as low as 69.9 dBa.
Extended service intervals — 500-hour engine oil change intervals, 5,000-hour hydraulic oil change intervals, and 1,000-hour greasing intervals — help reduce operating costs. Wide-open panels and ground-level access to grouped lubrication points allow for easy access during maintenance.
