摘要

An articulated fluid loading arm especially for transferring gasoline or other fuels from a bulk storage reservoir into the bottom of a tank truck or other fluid transport vehicle. The arm is pivotally mounted on a generally vertical riser, and includes an inboard arm section connected to the riser through a vertical swivel joint assembly, an outboard arm section connected to the inboard section through another vertical swivel joint assembly, and a coupling assembly, connected to the outboard arm section by a horizontal swivel joint assembly, for coupling the arm to the inlet of a tank or the like. The outboard arm section comprises inner and outer pipe members interconnected through a horizontal swivel joint assembly that facilitates pivoting the outer member with respect to the inner member about a horizontal axis, and the outer member and the coupling assembly are counterbalanced about this horizontal axis by a counterweight or any of several other systems including springs, fluid cylinders, and gear assemblies.
