Economic haul distance of loader

Economic haul distance of loader

Earthwork volume

The term free-haul distance means a distance over which hauling material involves no extra cost. This distance is usually taken to be about 500 feet meaning that it is only for hauls longer than 500 feet that the limits of economic haul need to be considered. Table 10-1.Soil Conversion Factors (Conversion Factors for Earth-Volume Change)

Sep 28, 2010 · Wheel loaders will work best in a range from 200 to 450 to 490 feet optimally and 500 feet as a maximum distance. Using them for shorter hauls can get just as costly as going beyond the recommended range. Again, you need to match the wheel loader with the haul truck and watch the haul distances.
