Launched at the American Public Works Association (APWA) Congress and Exposition, the new CX75C SR mid-sized excavator from Case Construction Equipment features a Tier 4 Final engine with a diesel oxidation catalyst (DOC)-only cooled exhaust gas recirculation (CEGR) system.
According to our sister site, Better Roads magazine, the CX75C SR features a 5 percent improvement in fuel efficiency, a 7 percent faster cycle time, a 20 percent larger fuel tank, a 7 percent wider cab and a 9 percent increase in hydraulic power when compared to previous models.
Operating at 55.2 net horsepower and delivering a 12,800-pound digging depth, the 16,200-pound excavator has a 12-foot, 6-inch digging depth.
The Tier 4 Final engine works with a high-pressure common rail (HPCR) fuel injection system that reduces fuel consumption, while the DOC-only CEGR system removes the need for a diesel particulate filter (DPF).
With a minimum swing radius, the machine has three operating modes – auto, heavy and speed priority. Those modes work to boost fuel economy by matching the engine throttle and RPM on the jobsite.
The Auto Idle feature, which allows for multiple idle rates, and the automatic engine shutdown both increase fuel savings.
The excavator can use attachments such as high-capacity buckets, a wide dozer blade, four hand- or foot-controlled auxiliary hydraulic control systems and the option between rubber, rubber insert and steel-shoe tracks.
Larger than previous models, the cab includes a 7-inch full-color monitor and an optional rearview camera.
Additionally, the machine includes eye-level fluid gauges, swing-out coolers and a slider radiator cleaning net, as well as an optional Case SmartFit bucket tooth system and Case SiteWatch for telematics.
The company says it will release more information about the machine later this year.
