Abstract: A boom lockout device for use with a hydraulic front shovel comprising a first half and a second half, each of which comprises a flat ceiling and two flat side walls. The ceiling is situated between the two side walls and is joined to the two side walls along a longitudinal edge of the ceiling. The angle between the ceiling and each of the two side walls is approximately ninety degrees. The first half and the second half are bolted together around the cylinder rod. The boom lockout device is installed between the barrel and the mount of the boom cylinder to prevent the rod from retracting into the barrel.

Abstract: A water truck body comprising a floor, two side walls, a front wall and a rear wall, a plurality of cylindrical baffle bodies with open bottom ends, a top plate situated on top of each of the cylindrical baffle bodies so that the cylindrical baffle body is centered underneath the top plate, and a tubular support structure. Each of the plurality of cylindrical baffle bodies comprises a plurality of apertures configured to permit liquid to flow through them. The tubular support structure is configured to hold the top plates and provide structural stability to the side walls, front wall and rear wall.

Abstract: A method for converting a dump truck body into an improved truck body. The dump truck body is configured for hauling a payload and has a canopy, a floor, two sidewalls, and a front wall. In a preferred embodiment, the method comprises: if the dump truck body has a tailgate, removing the tailgate; extending the floor to the rear by adding a floor extension component at a floor angle approximately ten degrees greater than a pre-conversion floor angle; increasing the height of the sidewalls by adding two fabricated sidewall attachment components; and tying the sidewall extensions into the rear of the floor extension component by adding a fabricated component. Preferably, a material dam is incorporated into the canopy forward of the front wall to form a shelf that is configured to retain and balance the payload.
