Case Construction Equipment this week introduced three new F Series wheel loader models and three new C Series full-size excavator models at the World of Concrete show in Las Vegas.

The new F Series wheel loader machines provide faster acceleration, quicker cycle times and higher travel speeds while delivering as much as 17-percent greater fuel efficiency.

The new Case 721F, 821F and 921F wheel loaders evolved from the company’s E Series product line. The Case F Series wheel loaders use selective catalytic reduction technology to meet Tier-4 interim emissions standards while also delivering increased power and improved fuel efficiency.

“With the SCR technology in our Case F Series wheel loaders, Case has made what was already the industry’s most fuel-efficient line of wheel loaders even more fuel efficient,” said Tim O’Brien, marketing manager, Case Construction Equipment. “At the same time, the Case F Series engines are more powerful and respond faster.”

The newly introduced C Series excavator line features increased fuel efficiency, productivity and improved serviceability and operator comfort.

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 improved horsepower. These three new models deliver 177, 207 and 266 net horsepower, respectively.

“Contractors are looking for lower operating costs and higher productivity,” said O’Brien. “The new Case C Series excavators deliver both. 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.”
