3D-MC: How to create 2D slopes

2D Slopes

  • The 2D mode offers the operator the ability of creating two types of slopes. Simple Slopes and Complex slopes. 
  • The slopes are created under the Tools Menu options.

Known slope

  • To create a simple sloping surface, press the Power button on the display, then tap Tools > Known Slope. Enter a slope percentage, or both the rise and run, to create the 2D surface.

Known Dual Slope

  • To create a known dual slope, press the Power button on the display, then tap Tools > Known Dual Slope.
  • Enter a percentage, or both the Rise and Run for each slope.

Measure Slope

  • To create a simple sloping surface by measuring two points with the bucket, press the Power button on the display, then tap Tools > Measure Slope. Follow the on-screen instructions.
  • Once the two points are measured, the surface is created. 

Complex Slope

Complex slopes are created in a series of segments. The segments are added and shown from left to right. When adding or editing a segment, any two of the four parameters may be entered to calculate the remaining parameters.

To create a complex slope, do the following.

  1. Press the Power button on the display, then tap Tools > Complex Slope. The Complex Slope screen appears.
  2. To add a slope element, tap Add and enter the parameters on the Slope Element screen.
  3. Tap OK to return to the Complex Slope screen.
  4. On the Complex Slope screen, move the bucket* or laser** transmitter to the desired transition location and tap OK to return to the main screen.
  5. On the main screen, tap the Elevation Control Button and reference the elevation with Zero to bucket or Zero to laser.

Tip: To view the appropriate slopes and directions on the main screen, the slope or the view may need to be reversed. Tap and hold on the screen to activate the on-screen pop-up menu. On the pop-up menu, the Show reversed option appears. You can also tap Tools > Reverse slope direction.

* bucket selection defines the starting point for the bucket

** laser selection defines which surface the laser is set to match

Zero to bucket

When the excavator is starting for the day, or moves its tracks to a new location while working, an elevation reference must be established. In the Elevation Control Button menu, tap Zero to bucket to touch the bucket to a known reference point and set the elevation reference to zero. Elevations are then calculated for the area within the reach of the excavator. If the excavator moves to a different location, or tracks are counter rotated, repeat the process to follow the elevation or slope.

Tip: The operator places the bucket on known good grade and is able to match the existing grade. It’s only as accurate as the grade being matched.

Zero to laser

Set up a laser transmitter over a known point and mount a laser receiver on the stick of the excavator. When the laser receiver is in the path of the transmitted laser beam, tap Zero to laser to zero out the elevation so that all elevations within the reach of the excavator are known.

Tip: Each time the tracks are moved, the operator will lower the stick until laser receiver is within the beam and reference the laser. The system will determine the new bucket elevation eliminating elevation errors.
