Patent ID: 11255072

Abstract:
A method and apparatus for digging and removing excavated material provides a mobile device, having a movable or self-propelled chassis, and an elongated, preferably articulated boom with a free end portion having an excavating implement (e.g., digging, excavating or jetting tool). The boom has at least three sections that are foldable to a storage position on the chassis wherein one boom section stacks upon or is aligned with another boom section. The vacuum line is supported upon the boom, extending along the boom and above the earth's surface, wherein the vacuum line extends between the free end portion of the boom and the chassis. The boom attaches to the chassis at a base. The excavated material is vacuumed with the vacuum line into a collection vessel or tank that can be a part of a wheeled vehicle. A separate vacuum truck can provide a vacuum to a selected collection tank.
