Case

The new Case CX250C excavator is one of three models to replace Case’s B Series product line. It features Tier 4 Interim-certified cooled exhaust gas recirculation technology that burns cleaner while delivering 177 net hp. The new Case Intelligent Hydraulic System technology reduces total fuel consumption and improves performance. Boom Economy Control lowers engine RPMs during the boom down and swing operation, while 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 an automatic pressure adjustment during digging operations. The CX250C has up to 6 percent more lift capacity and boasts an operating weight of 55,400 pounds to tackle bigger jobs. The cab provides 7 percent more overall space and 25 percent more airflow. Air conditioning performance also has increased by 8 percent. A new rearview camera feeds video to a 7-inch LED monitor in the cab to expand the operator’s view around the machine. 262.636.6011, casece.com

Doosan

The DX210W offers the most horsepower (161 hp), breakout force (bucket: 28,800 foot/pounds; arm: 21,728 foot/pounds) and digging depth (19 feet 9 inches) in the Doosan wheeled excavator lineup. Equip your DX210W with a dozer blade or outriggers using the bolt-on design. The front axle oscillates and provides an excellent steering angle for transport but can be locked for better digging and lifting performance. The rear axle is fixed. The transmission is mounted directly to the rear axle for protection from obstacles and optimum ground clearance. An advanced disc brake system works directly on the hub instead of the drive shaft to avoid planetary gear backlash. This eliminates the rocking effect associated with working free on wheels. A new travel motor and transmission control in the driveline provide comfortable travel thanks to increased smoothness and improved hydraulic retarding and gear shifting. doosanequipment.com
