Abstract: A bottom loading arm for bulk liquid carriers, such as gasoline tank trucks, is disclosed. In accordance with the invention, a single continuous reinforced flexible loading hose extends horizontally over large radius arcs from a vertical supply standpipe to a pendant bulk carrier connector. The arrangement is held in such large arcs by a pair of pivot arm means mounted for vertical and horizontal pivotal motion on the standpipe. One of the pivotal arm means is supported by horizontal arm means horizontally rotatable on the standpipe. The other pivotal arm means in turn is pivotally mounted at the outer or forward end of the first pivotal arm means. A vertically pendant portion of the flexible loading hose and the carrier connector is thus supported from the pendant end of the other pivotal arm means. The pivot arm means, hose and connector are counterbalanced by counterweight means supported on the other end of the first pivot arm means which extends rearwardly beyond the standpipe.
