The CX470C full-sized excavator is the newest in the Case C Series excavator line that features increased fuel efficiency, productivity and improved serviceability and operator comfort, while achieving Tier IV Interim certification.
The new Case CX470C excavator replaces the company’s CX470B model. It features Tier IV Interim-certified cooled exhaust gas recirculation (CEGR) technology that burns cleaner while delivering increased horsepower.
The CX470C, rated at 362 net hp (270 kW), is available in long undercarriage (LC), retractable undercarriage (RTC) and mass excavator (MEX) models, with operating weights ranging from 105,300 to 108,600 lb. (47,763 to 49,260 kg). The CX470C models are roughly 1,100 lb. (500 kg) heavier than the previous model for improved capacity.
The CX470C MEX is designed for heavier loads and larger buckets (up to 4.13 cu. yds. [3.16 cu m]), achieving higher productivity in large excavation jobs and high-volume truck loading. The retractable undercarriage version provides undercarriage width adaptability for transport between job sites.
“In today’s extremely competitive economy, contractors need machines that will reduce operating costs and boost productivity. The new Case CX470C excavator delivers both,” said Tim O’Brien, brand marketing manager, Case Construction Equipment.
“The CX470C joins a product line from Case that sets new standards in fuel economy, productivity and operator environment,” O’Brien said.
Like other excavators in the Case C Series, the new CX470C features Case intelligent hydraulic system technology that reduces total fuel consumption and improves performance.
Boom economy control (BEC) automatically reduces engine RPMs and hydraulic power to the boom when speed and power is not a priority, such as when swinging back to the hole. Swing relief control (SWC) technology manages the hydraulic power allotted at the start of the swing operation, and spool stroke control (SSC) creates an automatic pressure adjustment to meet demand during digging operations, but without building unnecessary pressure. Then, the feature of auto economy control (AEC) lowers RPMs when the joysticks are inactive.
Also boosting fuel economy and performance are engine improvements such as computer-controlled fuel delivery and variable geometry turbocharging, as well as automatic matching of engine performance and RPMs to power demands and hydraulic system requirements.
“Typical CEGR systems lose fuel efficiency, but with the Case intelligent hydraulic system technology and engine improvements, we’ve actually increased fuel efficiency on the Case CX470C excavator by 5 percent over our previous B Series model,” O’Brien explained.
With up to 5-percent faster cycle times than the previous model, the new Case CX470C excavator can move more material and load more trucks per hour., according to the manufacturer. Along with faster cycle times, the new Case excavator offers operators smoother and easier control and maneuverability.
The CX470C excavator provides 6-percent more lift capacity than the previous B Series model. With its standard arm length of 11 ft. 1 in. (3.38 m), the Case CX470C excavator has a maximum dig radius of 39 ft. 4 in. (12.0 m), a maximum dig depth of 25 ft. 4 in. (7.72 m) and a dump height of 25 ft. 5 in. (7.74 m).
The boom and arms, as well as the mainframe and undercarriage structure, have been redesigned for this additional capacity, delivering improved, world-class durability.
Its standard arm-digging force is 42,490 lb. ft. (189 kN) and standard bucket-digging force is 55,530 lb. ft. (247 kN). Available power boost technology increases both of these values by approximately 10 percent.
The CX470C features a 172 gal. (650 L) fuel tank and a 122 gal. (460 L) hydraulic system.
Improved Operator Environment
“The Case CX470C excavator provides a highly functional and comfortable environment for the operator, an important consideration in achieving maximum machine productivity,” O’Brien said.
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 72 dBa. “It’s like being in a car even when the excavator is running at full throttle,” O’Brien noted.
As in other C Series models, the cab on the new Case CX470C excavator provides 7-percent more overall space and 25-percent more airflow. Air conditioning performance also has increased by 8 percent. Standard rearview and optional sideview cameras feed video to a 7-in. high-definition LED monitor in the cab, enhancing operator confidence and job site safety during machine operation.
“The large, clear monitor in the Case C Series excavators compares favorably to what you’d find in a luxury automobile,” O’Brien said. The LED screen also presents 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,” he said.
The machine’s low profile design also enhances visibility from the cab, efficiently accommodating Tier IV emission system components without compromising the operator’s view of the job site, according to the manufacturer.
The CX470C excavator also includes a standard air-suspension seat and an in-cab auxiliary hydraulic setting system with a new option for 10 memory-recall, attachment-flow settings to make tool changes quick and easy for operators.
These improvements in operator comfort features are complemented by the added safety of a full ROPS structure around the cab.
Ease of Maintenance
“Extended service intervals for the Case C Series excavators help reduce operating costs,” O’Brien said. They are designed with 500-hour engine oil change intervals, 5,000-hour hydraulic oil change intervals and 1,000-hour greasing intervals with easy maintenance system bushings.
The cab includes new access points to easily reach the air filter and fuse box.
“The design of the CX470C excavator efficiently accommodates the redesigned engine, cooling and exhaust systems while offering excellent serviceability and operator visibility,” O’Brien said.
The machines feature wide-open panels for easy access to service points and ground-level access to grouped lubrication points.
Full Range of Attachments
Case offers a range of attachments for the CX470C and other C Series excavators, including Case smart digging systems components such as pin-on buckets, coupler buckets, the Case multi-fit coupler and the SmartFit bucket tooth system.
The new Case pin-on buckets are available for the CX470C in heavy duty, heavy duty high-capacity, severe duty, and rock digging type designs, allowing the machine to be productive in a wide range of applications. The Case multi-fit coupler offers complete hydraulic latching, enabling excavator operators to quickly attach and detach buckets and other components without leaving the cab. Designed for the multi-fit coupler, Case coupler buckets feature integrated bucket pins to prevent any loss of breakout force that might otherwise occur when using a coupler device.
The SmartFit is a hammerless quick-change system that provides stronger, self-sharpening teeth and reusable adapters and locking pins. The SmartFit lineup includes general purpose, rock chisel, heavy penetrator, tiger, twin tiger and flare teeth.
