Case Construction Equipment - CNH

C Series Excavators

Case claims its new CX250C, CX300C and CX350C -- first of the C Series excavators -- are up to 10% more fuel efficient than its B-Series predecessors, a noteworthy accomplishment considering the B Series machines earned the Energy Conservation Award bestowed by Japan’s Agency for Natural Resources and Energy. Power has been turned up to 177, 207 and 266 net horsepower, respectively, in the Isuzu diesels certified to Tier 4 Interim emissions standards with cooled exhaust gas recirculation (CEGR) technology. The new Case Intelligent Hydraulic System technology reduces total fuel consumption and improves performance several ways.

  • Boom Economy Control lowers engine RPMs during the boom down and swing operation
  • 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
  • Spool Stroke Control creates an automatic pressure adjustment during digging operations

Case also says the machines have up to 5% faster cycle times than previous models, allowing them to load up to 10 more trucks during every work shift. And the machines are rated with up to 6% more lift capacity.

The CX250C has an operating weight of 55,400 lbs., and the CX300C and CX350C weigh in at 65,900 lbs. and 80,000 lbs., respectively.
