The CX350C improves fuel economy by as much as 15 percent, offers 5 percent faster cycle times, and provides greater power and performance compared to previous models thanks to its exclusive CASE Intelligent Hydraulic System. Featuring an operating weight of 80,000 pounds, the CX350C offers up to 6 percent more lift capacity, as well as advanced CASE technologies that optimize power and efficiency, including Boom Economy Control, Auto Economy Control, Swing Relief Control and Spool Stroke Control. 262.636.6011,

Hyundai Construction Equipment Americas

The new R480LC-9A and the R520LC-9A crawler excavators include a certified Interim Tier 4 engine upgrade, improved hydraulics, increased operator comfort and more durability. The R480LC-9A and R520LC-9A boast respective operating weights of 108,420 pounds, and 114,820 pounds. Hyundai has powered each of these 9A earth moves with a low emission, low noise, Cummins Interim Tier 4/Stage IIIB QSX11.9 engine. This engine has one of the highest power-to-weight ratios in its class, and its torque rise (up to 50 percent) enables the engine to quickly take full advantage of the torque power. Other innovations such as the variable speed fan clutch, two-stage auto decel system and the economy mode help to conserve fuel and reduce environmental impact. Plus, operators can choose between three unique engine modes – Power, Standard and Economy – which enable the machine to switch between full power and reduced fuel consumption according to the user’s preference. 877.509.2254,

To achieve added fuel savings, the design of the Cat 336E H uses three building block technologies that 1) conserve fuel with engine power management via the Cat Electronic Standardized Programmable (ESP) pump, which smoothly transitions between the hydraulic hybrid power sources, engine and accumulator; 2) optimize performance using restriction management via the patented Cat Adaptive Control System (ACS) valve, which intelligently manages restrictions and flows to seamlessly control machine motion with no loss of power, and to ensure operators experience no difference in control, hydraulic power or lift capability; and 3) reuse energy via the hydraulic hybrid swing system, which captures the excavator’s upper structure swing brake energy in accumulators, and then releases the energy during swing acceleration.
