CX470C Offers Increased Performance and Economy

Case Construction Equipment is introducing the CX470C a powerful Tier 4 Interim heavyweight crawler excavator offering a 6% increase in lift capacity, greater digging efficiency, reduced emissions and up to 5% lower fuel consumption. The machine features a larger, more comfortable operator's cab, delivering lower noise levels and improved safety. Advanced hydraulic control systems contribute to increased efficiency and lower fuel use.
Power To Deliver
Replacing the popular CX470B, the CX470C uses a 9.8 litre Tier 4 Interim certified diesel engine with cooled exhaust gas recirculation (CEGR). Maximum power of 362hp (270kW) is produced at just 2,000rpm and delivered to the operator by Case Intelligent Hydraulic System technology.
This includes Boom Economy Control to automatically reduce engine revs and hydraulic power to the boom when speed and power are not a priority. Swing Relief Control manages the hydraulic power supplied at the start of the swing operation, while Spool Stroke Control automatically adjusts the hydraulic pressures to meet the demands of digging operations.
An Auto Economy Control automatically lowers engine revs when the joysticks are inactive, lowering fuel consumption. Fuel delivery is also computer-controlled in the Tier 4 Interim engine, which combined with variable geometry turbocharging allows the engine performance and revs to be automatically matched to hydraulic system and power requirements.
As well as providing rapid response to operator requests for power, through the hydraulic levers, this contributes to a 5% increase in fuel efficiency. The machine also delivers up to 5% faster cycle times, increasing productivity and boosting profitability for the customer.
Operator Comfort Improvements
The ROPS/FOPS Case C Series cab, with external protective cage, offers a comfortable working environment for the operator, with 7% more internal space and 25% more airflow from the improved air-conditioning system, which has 8% more power. Despite this additional airflow, internal noise levels have been reduced to just 73dB(A), a 2dB(A) reduction providing an almost car-like interior environment.
The CX470C has a high definition 178mm LED monitor in the cab, providing all necessary system information, including fuel consumption data. This monitor also provides a full colour screen for the standard rear view and optional side view, camera feeds.
Four Machines In One
The CX470C is available with a long undercarriage (LC) or a retractable undercarriage (RTC). Both undercarriages can also be specified on standard or mass excavation (ME) specification models. The CX470C ME will take centre stage on the Case stand at this year's Intermat exhibition.
Operating weights range from 47.7 tonnes to 49.2 tonnes, approximately 500kg heavier than the previous models. The LC machines are offered with a choice of heavy duty dipper sticks, at 2.5m and 3.4m. The CX470C ME uses the smaller 2.5m dipper as standard, with a shorter 6.55m monoboom. Lift capacity on the LC chassis is increased from 9,900kg to 10,500kg, while the ME undercarriage machines offer an increase from 9,740kg to 9,890kg.
As with all C Series excavators, there is a range of buckets and attachments available for the CX470C, all of which are compatible with the CXB range. These include Case Smart Digging Systems components such as pin-on buckets, coupler buckets, the Case Multi-Fit Coupler and the SmartFit bucket tooth system. Pin-on buckets are available in heavy duty, heavy duty high capacity, severe duty and rock digging designs, allowing the machine to perform in a wide range of operations.
Case excavators benefit from 1,000 hour greasing intervals on all pins except the bucket pins. With 500 hour engine oil changes and 5,000 hour hydraulic oil change intervals, this ensures maximum uptime for the operator, boosting productivity in all applications.
