I am working on a site plan that involves loading docks for semi trucks with 53' cargo trailers. The project is under construction and as the site is being graded my client is concerned with the driveway and potential dragging at the driveway. I am using AutoPath software to model the vertical path of the truck along the trucks exit/entrance path profiles. At first run there were no problems with the WB-67 truck in the software. Then i was informed that the ground clearance at the landing gear is only 8". I adjusted the WB-67 truck for landing gear clearance of 8" and now i have big problem. Can anyone confirm the ground clearance on for the landing gear? I have searched and searched but cannot find anything on the landing gear ground clearance. Thanks so much!
