Abstract
Apparatus for positioning a load in any orientation. The apparatus includes a base with an attached lift arm that has a plurality of members slidably interconnected. At least one of the plurality of members is pivotally attached to the base, and a rotatable connector is attached to at least one other of the plurality of members opposite the base. A carriage is provided at the distal end of the lift arm. The carriage includes a carrier pivotally attached to the rotatable connector and a track slidably connected to the carrier. Straps and clamps secure a load such as a pipe to the carrier. The apparatus also includes a hydraulic power system to position the lift arm and the carriage. The power system controls (a) pivotal movement of the lift arm about the pivot connection between the base and the lift arm, relative to the base, (b) translational movement of the plurality of members relative to each other along the slidable interconnections, (c) rotational movement of the rotatable connector relative to the plurality of members, (d) pivotal movement of the lift arm relative to the carriage, and (e) translational movement of the track relative to the carrier. Using the load positioning…
