Case Expands Compact Excavator Line

May 2011, Vol. 66 No. 5

Case Construction Equipment expands its compact excavator product line into a new class segment with the introduction of the Case CX55B minimum tail swing model.

With a large boom and arm for greater reach, the CX55B delivers 11,240 pounds-foot of bucket digging force. This model boasts a 39.3-hp engine, operating weight of 12,295 pounds and dig depth of 12 feet 10 inches. Plus, its compact size and cab height of 8 feet 4 inches make the Case CX55B excavator as easy to trailer between jobsites as a skid steer.

The full-size cab design is 10 percent larger and 7 inches wider than other Case B Series compact excavator cabs. Large front and rear windows improve operator visibility. A new slide-up front window improves airflow and helps the operator communicate more effectively with coworkers near the machine. The Case CX55B is “thumb ready” with factory-installed hydraulics and an attachment bracket. The machine is also available with piping for secondary hydraulics to handle a wide range of attachments or provide a dedicated circuit to a thumb bucket.

In addition to a variety of available attachments – including buckets, hammers and augers – CX55B includes a standard dozer blade for finish grading. The blade features a 38-degree approach angle, and its shape rolls the dirt as it pushes, leaving a smooth and level surface. An optional four-way dozer blade is also available for increased backfill and grading ability. Case offers both rubber and steel tracks for the CX55B to match the ground conditions.

A center-swing boom enables the operator to dig around stationary objects or alongside obstacles. Minimum tail swing allows the machine to rotate 360 degrees with less than 11.7 inches of the upper structure extending beyond the tracks.

The 19.8-gallon fuel tank is 40 percent larger, boosting operation time. Available buckets range from 12 to 36 inches, with capacities from 3.0 to 9.8 feet3.

For fast and easy daily maintenance, there is ground-level access to daily maintenance checkpoints; an easy-access electrical compartment is under the seat; and an hour meter can be checked from the ground outside the cab. The radiator features a new intake method that simplifies cleaning and helps prevent clogging. New features include a “no tools” fuel-tank drain valve and an accumulator that allows attachments to be safely lowered using in-cab controls in the event of an unexpected engine shutdown. www.casece.com
