Caterpillar has released new software that expands the capabilities of the AccuGrade grade control system, the Cat factory integrated, sensor-independent solution for machine control and guidance. The new on-board software, CD700 v. 11, and new office software, AccuGrade Office v. 7.2, provides software support for three new machine families-wheel loaders, wheel dozers and towed scrapers.
New, more capable configurations also are offered for track-type tractors, motor graders and hydraulic excavators. AccuGrade systems continue to support soil compactors and wheel tractor-scrapers.
The new software includes Sky Plot, which allows the machine operator to view GPS and GLONASS satellites available when using MS980 or MS990 receivers. The operator also can enable or disable use of the GLONASS satellite constellation from the cab when using the MS990 receivers. The capability can help ensure optimum satellite coverage for fast start-up and accurate operation.
The new software also enhances diagnostic support information. AccuGrade Office wireless users now can remotely retrieve radio settings, machine measurements, valve calibration tables and machine settings. The capability speeds diagnostic and calibration tasks.
Enhanced capabilities for specific machines
The new software provides specific benefits for each machine type. For example, on hydraulic excavators the CD700 display now supports site and laser reference, which can be used when GPS or the Universal Tracking System (UTS) are not available. The system supports single GPS, which provides a lower cost entry level 3D system. Similarly, single UTS support allows use of a 3D design when GPS positioning is not available.
Also on hydraulic excavators using the CD700 display, profile and cross-section views are available simultaneously to the machine operator so that all critical dimensions are in view. Additionally, the new system enables excavator bucket center guidance, which improves accuracy when working on side slopes.
On motor graders, dynamic pitch allows the operator to maintain accuracy when rolling the blade during grading. A blade pitch sensor and a mainfall sensor are required, but the system eliminates the need for the operator to keep the mast vertical when using GPS or UTS.
For the D8T, D9T and D10T track-type tractors, an entry level, indicate-only system is available for earthmoving and early site preparation tasks. The system uses a single, cab-mounted GPS antenna.
