Case improves wheeled excavators

29 Oct 12 Case Construction Equipment has unveiled the first three models in an improved range of wheeled excavators.

The WX148, WX168 and WX188 have a three-pump hydraulic system, with a dedicated swing pump, a new engine speed/working mode selection dial, a heavy-duty undercarriage and an improved operator’s cab.

According to the manufacturer, the revisions result in improved operator comfort and ease of operation and reduced ownership costs.

The three-pump hydraulic system has one pump dedicated to the slew function. This provides continuous movement and allows the operator to multi-function the controls, withcontinuous movement while digging and grading. The hydraulics are managed by the Case Intelligent Hydraulic System control with a single CPU for improved controllability and simplified diagnostics.

Automatic Powerboost is included on all three models for heavy breakout and lifting operations. There is also an automatic power increasein travel mode.

A new engine speed and new working mode selection dial provides a single point of contact for the operator when setting the machine to work. This dial delivers low idle speed, Lift 1 and 2 modes for dedicated lifting work, Eco working modes 1, 2 and 3, plus a Heavy Mode for maximum excavating performance. There is also a dedicated road travel mode for rapid relocation between sites.

Case Intelligent Swing (CIS) allows the operator to adjust upper structure slew speed to suit a variety of work sites. The machines offer four swing acceleration settings and three deceleration settings.

A new fully automatic hydrostatic powershift transmission is directly mounted to the rear axle for maximum ground clearance. With new heavy duty ZF axles, the excavators deliver high travel speeds up to 35km/h, yet also provide total control on site through a creep speed function.

The ROPS/FOPS operator’s cab has automatic air conditioning, air-suspended seat and completely adjustable controls. All travel functions have been centralised on the steering column, with other switchgear grouped for ease of reach. A new LCD multifunction monitor provides information for the operator and integrated diagnostic functions for service engineers.
