Adapting the Off-Highway Truck Body Volumetric Process to Real World Conditions

SAE Standard J-1363 Jan 85 reaffirmed Nov 95 has served the off-highway truck industry well. However as off-highway trucks have become larger, now approaching 400-ton capacity versus 170-ton or maybe 190-ton in the mid-1980's, and as mining operations have become more sophisticated, pennies are counting where dollars used to. And with parametric 3-D CAD design becoming the norm, the need and the possibility of more accurately defining the reality of what an off-highway truck body will carry and where that load will rest fore-to-aft on the truck chassis has become paramount. With a single tire on a 300 ton plus capacity off-highway truck costing in excess of $25,000 to $30,000, proper load placement and accurate truck loading are absolutely essential. The Load Profiled ™ off-highway truck body design approach incorporates specific field operating parameters, i.e. material characteristics, density and angles of repose to provide an off-highway truck body that is site-specific /sized to the actual operation where the off-highway truck will be used.
