Abstract
Abstract A fluid transferring apparatus, of the marine loading arm variety, with an hydraulic-powered single-counterweighted system for balancing the apparatus and maneuvering it both horizontally and vertically. The apparatus is fully counterbalanced when it is filled with fluid, thereby imposing no load on the structure to which its outer end is connected during fluid transfer, and the power system provides positive control of the apparatus at all times, along with safeguards against accidents in the event of power and/or operator failure.
