PROCESS FOR THREE-DIMENSIONAL MODELING AND DESIGN OF OFF-HIGHWAY DUMP BODIES

摘要

A method of loading material into a dump body of a truck using a loading bucket whose sidewalls are spaced relatively wider than conventional dump bodies of similar volumetric capacity is disclosed. The method involves filling the loading bucket with ati amount of earthen material, where the loading bucket has a volumetric capacity that is approximately 1/4 or more than a volumetric capacity of the dump body. The loading bucket is positioned over the dump body so that the loading bucket is approximately centered over a floor of the body. The bucket is lowered to a position that allows a swinging door of the loading bucket when opened to (1) release the earthen material and clear the floor of the dump body and (2) hit the sidewalls of the dump body if the loading bucket is moved off center over the floor. The swinging door is freed so as to open the bucket and allow the material held in the bucket to drop into the dump body, whereby the door swings open and clears both the sidewalls and the floor of the dump body while minimizing the height from which the material is dropped from the bucket.
