ABSTRACT:
An articulated fluid loading arm for delivery of gasoline or other liquids through a drop pipe into a tank truck or railway tank car. The arm is equipped with a control system comprising a hydraulic jack for regulating the angle defined by the inboard and outboard arm sections, a sensor system that senses a change in the attitude of these two arm sections and actuates the hydraulic jack to maintain the drop pipe in an established azimuthal position as it is lowered into and raised out of the tank truck or tank car hatch, and means for adjusting the sensor system to make it functional for various locations of the drop pipe.
