<p>There is disclosed a loading arm for transfering liquids, gases, and particulate solids, in which the loading arm comprises a riser, inner and outer arm sections, and a rotary pipe joint pivotally interconnected and removably attached to both the inner and outer arm sections for rigidly interconnecting and supporting the arm sections in an arm-assembled position while the rotary pipe joint is being serviced or repaired. The arrangement is particularly advantageous for servicing sealing and bearing means located in the rotary pipe joint. Such joints are used in loading arms employed in transfer apparatus used to conduct cargo between transport and storage containers, for example, a marine transport vessel and wharf, pipeline, or other stationary facility.</p> |
