Case Excavators Offer Advanced Fuel Economy

Case Construction Equipment introduced the new Tier 4 interim CX130C and CX160C excavators to its C Series product line, offering customers fuel economy increases of up to 8 percent and 5 percent, respectively, versus previous B Series models; resulting in increased productivity, along with lower overall owning and operating costs facilitated through easier maintenance.
“The power and efficiency of the new C Series excavators, due in part from the optimization of their hydraulics system, makes them ideally suited for utility projects and road projects,” said Rob Marringa, brand manager, Case Construction Equipment. “In addition, the CX130C and CX160C have been designed for easier transport at the end of the day for secure storage.”
Both the CX130C and CX160C excavators achieve 100/124 net hp (75/92 kW) using Tier 4 Interim-certified cooled exhaust gas recirculation (CEGR) technology that burns cleaner while delivering superior horsepower.
“On top of the power of these new Case excavators, both of them stretch fuel dollars while delivering the higher productivity that contractors expect,” said Marringa. He cited for the CX130C a 4-percent lift capacity increase among crucial product improvements. For the CX160C Case has engineered a 3-percent cycle time reduction and a 2-percent lift capacity increase.
“Advancements made in the Case Intelligent Hydraulic System technology reduce total fuel consumption and improves performance,” Marringa said.
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. Blended hydraulic functions provide faster transition for lift/dump movements to dig/curl, improving truck-loading time and jobsite efficiency.
He continued, “Because excavators run with little change to engine speed, CEGR technology was the best choice for efficiency and convenience.”
With 3-percent faster cycle times than previous models, the new Case CX160C excavator can load more trucks or trench further during every work shift than its predecessor model. Both of these new Case excavators offer operators smoother and easier control and maneuverability. The CX130C/CX160C provide 4 percent/2 percent more lift capacity and boast a 440 lb. (199.6 kg) increase in operating weight to tackle bigger jobs.
The new excavator offers three power modes – SP (speed priority), H (heavy duty) and A (automatic) – to allow operators to choose the best mix of power and fuel efficiency. The throttle settings also adjust the hydraulic settings for further tailoring to specific tasks.
For these new machines, more comfort results in greater operator productivity. Compared to the previous B Series models, the Case CX130C/CX160C excavators give operators a more spacious, comfortable and quiet cab. The excavators’ very low profile that Case designs into all C Series models contributes to the cab’s 19-percent better visibility from the operator’s seat (including a new roof skylight) as compared to previous models.
“The high definition, non-glare monitor in the Case C Series excavators is large and clear,” Marringa said. The operator can easily switch between rear and optional side camera views. The cameras have simultaneous visibility to key operating data, including a new function, which provides fuel consumption per hour. Operators can use this information to refine fuel efficiency for their particular operation. The CX130C/CX160C excavators also include an in-cab auxiliary hydraulic setting system with a new option for 10 memory-recall settings to make tool changes quick and easy for operators.
Noise reduction improvements, including vibration refinement on the cab’s reinforced tubular structures, create an extra-quiet cab environment, with automotive-like noise levels as low as 69.9 dBa.
New with the C Series is a rearview camera that feeds video to a 7-in. LED monitor in the cab, enhancing operator confidence and jobsite safety during machine operation.
A Level 1 ROPS/FOPS (rollover/falling-object protection systems) cab structure provides helps enhance operator safety.
