New Case C Series excavators deliver improved fuel economy, faster cycle times
The new Case CX250C, CX300C and CX350C excavators replace models in the company’s B Series product line. They feature Tier 4 Interim-certified cooled exhaust gas recirculation (CEGR) technology that burns cleaner while delivering superior horsepower. These three new models deliver 177, 207 and 266 net horsepower (132, 154 and 198 kW), respectively.
“Contractors are looking for lower operating costs and higher productivity. The new Case C Series excavators deliver both,” said Tim O’Brien, marketing manager, Case Construction Equipment. “In trenching applications, for example, the Case CX250C excavator can save as much as three gallons of fuel per hour compared to competitive models. If an equipment owner puts 1,000 hours on a machine in a year, he can put $9,000 straight to the bottom line.”
The new Case Intelligent Hydraulic System technology reduces total fuel consumption and improves performance, O’Brien 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.
“These fuel efficiency gains are especially significant,” O’Brien explained. “While typical CEGR systems lose fuel efficiency, we’ve actually increased fuel efficiency on our Case C Series excavators by up to 10 percent over our previous B Series models. This is noteworthy considering that the Case B Series excavators earned the prestigious Energy Conservation Award, bestowed by Japan’s Agency for Natural Resources and Energy, due to its fuel efficiency. While delivering exceptional fuel efficiency, the Case
C Series models continue to be in the top of their class for productivity.”
Increased productivity
With up to 5-percent faster cycle times than previous models, the new Case C Series excavators can, for example, load up to 10 more trucks during every work shift. Along with faster cycle times, the new Case excavators offer operators smoother and easier control and maneuverability.
The three C Series models feature up to 6-percent more lift capacity and boast increased operating weights to tackle bigger jobs. The Case CX250C excavator has an operating weight of 55,400 lb. (25 100 kg), and the CX300C and CX350C weigh in at 65,900 lb. (29 900 kg) and 80,000 lb. (36 300 kg), respectively.
Improved operator comfort, visibility
“With the Case C Series excavators, operators also benefit from working in a more spacious, comfortable and quiet cab,” 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 69.9 dBa. “It’s like being in a car even when the excavator is running at full throttle,” he said. “A quiet, comfortable cab helps the operator be more productive.”
The cab on the new Case excavators provides 7-percent more overall space and 25-percent more airflow. Air conditioning performance also has increased by 8 percent.
New with the C Series is a rearview camera that feeds video to a 7-inch LED monitor in the cab to expand the operator’s view around the machine. “The monitor in the Case
C Series excavators is large and clear, comparable to what you’d find in a luxury automobile,” O’Brien said. The operator can easily switch between rear and optional side camera views. Plus, they 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,” he said.
The C Series excavators also include a standard air-suspension seat and 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.
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.
Ease of maintenance
“The new Case C Series excavators efficiently package the redesigned engine, cooling and exhaust systems while maintaining 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 C Series excavators, including buckets and multi-fit couplers. The new line of Case excavator buckets, including general-purpose, heavy-duty, ditching, rock and Couplex™ application buckets, are all available with the Case SmartFit™ durable bucket tooth system with tips that can be switched without hammering pins.
