BucketWheel is Carlson Software’s machine guidance product for bucket wheel excavators. It enables operators to know their grade and location without the need for stakes and in blinding conditions. Accordingly, when work is done at night, when a surveyor may not be available, production can continue with confidence. The existing surface is updated as the continuous excavation equipment moves large volumes of soft materials. This surface is reported back to the engineers for material tracking and other calculations.


Benefits include:
  • Never over cut design limits
  • Less rework needed
  • Lower dilution
  • Increased productivity
  • Tremendous time savings over the length of the project
  • Real-time “as-built” survey
  • Low cost alternative
  • Easy to learn
  • On-site support
  • Level terrain leads to less wear and tear on equipment

The system is comprised of a single antenna GPS with cm-level accuracy, a tilt sensor, and a ruggedized touch-screen computer. The BucketWheel machine guidance software uses plan view features and design surfaces to aide the bucket-wheel in achieving the desired plan by proper positioning. Operators glance at a screen mounted in the cab and respond to cut/fill and position information. This empowers the employee by giving them instant feedback on their design performance and allowing them to achieve the proper grade with the first pass. This eliminates excessive movement and tramming of the machine, which results in less maintenance and cost.

When working to a centerline, a valuable tool is available in Carlson’s BucketWheel software to speed the process and give control where it is needed. The program visually displays centerline, station/chainage, and offsets to the operator. It is simple to switch between design files and almost easier to select a polyline on the screen and have that become your new centerline. BucketWheel does all of this, helping you get the job done quickly and safely.

Grade Screen

The BucketWheel grade screen, provides the views for the operator to easily navigate and read the cut/fill values. The main screen displays the plan view on the left, cut/fill values on the right, and GPS status and current elevation at the top of the screen.

The lower right buttons allow the user to: change views; turn hatch on/off; access tools such as: monitor, show data, log point, or change polyline to centerline. It also displays stations (chainage) and offsets if a centerline is active.
Elevation differences can be determined from a Flat Pad Elevation or from an existing Design Surface Model. Entering an elevation allows for the operator to work without needing a surface designed by engineering software. By giving the operator this tool, if the machine is moved to a new working area that requires a change in elevation, the operator has the ability to continue working and reduce downtime.

Tracking Screens

TruckPro presents the operator with a loading information screen, along with a dumping location screen. The payload weight is read from an on-board sensor which is integrated with the TruckPro system. The pit and seam are filled in with the location extracted from the main navigation screen when the operator selects the record load location as seen in the next section. These values are all editable from these screens in case an override is needed.

The Leica GPS and Leica tilt sensor are supported. Currently there is no support for other brands of GPS or hardware; however, expansion could be warranted under special circumstances. Please consult with Carlson Software’s main office for more information.
