Cutting-Edge Trimble Technology Expands Earthmoving System Capability
New Version of SiteVision GPS System Supports Tilt-Bucket Excavators and Roading Applications
SUNNYVALE, Calif., Nov. 19, 2004 -- Trimble (NASDAQ:TRMB) introduced today a new version of its SiteVision® GPS system. This cutting-edge system is designed to enhance the performance requirements of excavators with tilt-bucket attachments. Trimble's SiteVision GPS sets a new standard for performing side-to-side tilt measurement of an excavator tilt-bucket attachment and offers additional features designed for roading applications.
The SiteVision GPS system uses dual GPS antennas to compute the position of the machine blade or bucket. An on-board computer determines the position of each tip of the blade or bucket and compares these positions to a design elevation. It then computes the cut or fill to grade. This information is displayed on the in-cab screen, and the cut/fill data is used to drive the valves for automatic blade control or passed to the SiteVision lightbars which guide the operator up or down for grade and right or left of a defined alignment.
With this new version, the GPS receiver measures 3D position of both bucket tips of a tilt-bucket. The SiteVision tilt-bucket feature allows the contractor to use a tilt-bucket attachment on an excavator when working on jobs involving digging to a sloped plane perpendicular to the boom's axis, such as trenches with sloped walls. The SiteVision system's AS300 solid state angle sensors are specifically designed for easy installation on excavators. The sensors are mounted on the boom, stick and tilt bucket linkage; the output is used to calculate the relative position of the tilt bucket teeth. This is combined with the GPS positioning to calculate an accurate 3D position and orientation. Since the AS300 sensors have no moving parts, they are more rugged and better suited for applications requiring high reliability. Additionally, the sensors can be submerged in up to 20 meters (66 feet) of water.
Contractors also now have a choice of using encoders for high-accuracy applications or angle sensors for increased ruggedness or underwater operations, making it ideal for contractors involved in dredging or other near-shore hydrographic applications.
Designed for use on all machine types, the SiteVision GPS system software offers a variety of new features:
