Overview: Haul Analysis (OptiHaul) allows you to calculate the optimum hauling directions for the Cut/Fill Map.

Appearance:
Calculation Grid Spacing (m or ft): The cell spacing of the grid that the haul analysis is calculated on.
Calculation Grid Direction (deg): The direction of the grid rotation.
Cut/Fill Ratio: The volume of cut / volume of fill and should be in the range of 1.1 to 1.5 depending on the soil type and its condition. We recommend following the Cut/Fill Ratio used in the landform design.
Import (m3 or yd3): The volume of soil to bring into the field boundary area from an external area. This volume is taken into account when balancing earthworks to the cut fill ratio.
Export (m3 or yd3): The volume of soil to remove from the field boundary area to an external area. This volume is taken into account when balancing earthworks to the cut fill ratio.
Swell Factor (%): Percentage of the soil from cutting the ground to swelling up to the scraper.
Scraper Capacity (LCM or LCY): The capacity of the scraper in Loose Cubic Meters (or Loose Cubic Yards) after it has swelled up.
Scraper Width (m or yd): The width of the scraper. If using tandem scrapers then width of a single scraper should be used.
Scraper Max. Cut/Fill (m or yd): The limit of the cut taken or fill dumped at one time to avoid the equipment cutting or dumping too deep for each pass.
Field Efficiency (%): Percent of time the machine is actually doing productive work.
Ave. Loading Speed (km/h or m/h): Average speed while the scraper is cutting soil.
Max. Haul Speed (km/h or m/h): Maximum speed while hauling a full scraper.
Ave. Dumping Speed (km/h or m/h): Average speed while dumping the soil in fill areas.
Max. Return Speed (km/h or m/h): Maximum speed when returning to the cut area with an empty scraper.
Acceleration Time (s): Time taken to get from loading speed up to maximum haul speed and from dumping speed up to maximum return speed.
Deceleration Time (s): Time taken to get from maximum haul speed down to dumping speed and to get from maximum return speed back down to loading speed.
