Case Construction Equipment’s upgrades to its N Series loader/backhoe product line include the application of cooled exhaust gas recirculation (CEGR) emissions-control technology to achieve interim Tier 4 certification.
The Case 580N, 580 Super N, 580 Super N Wide Track and 590 Super N loader/backhoes now feature 3.4L turbocharged engines ranging from 78 hp in the 580N to 108 hp in the 590SN. The interim Tier 4-certified engine burns cleaner while delivering superior horsepower, faster response, and up to 4% better fuel efficiency under load, according to the company.
Other new standard N Series features include automatic Ride Control on four-wheel-drive models that engages at roading speeds to help reduce bucket spillage; and remote hydraulic test ports that allow easy, ground level access for service diagnosis to keep the machine up and running, reducing the expense associated with downtime.
Case also has added a standard panel of dipper teeth on the bottom surface of the dipper, along with an optional extension/replacement pack that can expand the area of the dipper covered with serrated teeth. The dipper teeth enable the machine operator to secure unusually shaped or oversized pieces of debris or rock by pinning those objects against the dipper with the bottom of the bucket. The dipper teeth not only provide superior control of materials being moved, but they also protect the dipper from excessive wear.
The Case N Series loader/backhoes offer several transmission choices, including the Powershift S-TypeTM, Powershift H-TypeTM, and Powershuttle options. All transmission choices are available on the 580SN, 580SN WT and 590SN. The 580N offers the Powershift S-Type and Powershuttle transmissions.
The N Series machines deliver improved cycle times and efficiencies through the new Variable Volume Hydraulic (VVH) System. The VVH System operates at a lower temperature than competitive hydraulic systems. The 580N continues to offer a single gear pump open hydraulic system.
Marringa added that Case N Series loader/backhoes give contractors a solution for excavating, digging, carrying and loading, along with the ability to drive to a jobsite at up to 24 miles per hour.
