Abstract: Beam placement during bridge construction by a carriage moving across an abutment or pier, supporting the end of a beam or pipe to position and align it on the abutment. A lift assembly lowers the end and the carriage is disengaged and moved to receive another beam, placing multiple parallel beams, without requiring a large crane. A carriage formed in sections separates to return to a new position. A screw jack or hydraulic unit moves the lift assembly, and deposits the beam on a load plate, and opposed separately-operated lift plates connected by a hinged cross-bar may form a beam-receiving basket assembly. Carriage rollers bear against a channel iron that protects underlying concrete structure from damage. A first set of rollers may bear against a horizontal surface and a second set of rollers bear against a vertical face of the abutment, aligning the carriage and beam along orthogonal axes.

Abstract: An apparatus and method of root pruning a woody plant having a main trunk and usually a distinct crown, such as a tree. More particularly, the invention relates to an apparatus and manner in which to prune root systems of trees, in preparation of transplantation or while excavating in proximity to a tree, more efficiently and effectively than in the past. The invention includes among its essential elements a vibratory apparatus coupled to a mobile device. The mobile device may be an excavator machine having an articulated machine arm with the root pruning vibratory apparatus attached thereto. The machine's articulated arm positions the vibratory apparatus in a desired location while applying force to the apparatus, pushing it into the ground while the apparatus is vibrating, penetrating the blade into the ground or, optionally, the vibratory apparatus having the ability to provide a hammering action.

Abstract: An apparatus and method of constructing barrier wall structures. More particularly, the invention relates to a manner in which to use common building materials and methods in erecting a barrier wall system more efficiently than in the past. The apparatus includes among its essential elements a formed reinforcement cage; a plurality of spacers that are used to support the reinforcement cage; a plurality of cable anchors each being an elongated member having a first end and a second end, wherein the first end is anchored to the ground and the second end is adapted to be attached to a cable; a plurality of elongated cable members that connects the reinforcement cage and the anchor member; a plurality of cable gripping members for holding the cables taut wherein the cables secures in place the reinforcement cage; and, a formed outer concrete layer that is molded over the reinforcement cage.
