Abstract: A transfer arm for a fluid product includes a transfer pipe having sections linked by fluid-tight articulations and an end provided with a device for connecting the pipe to a target duct. A support structure for the pipe has an inner branch mounted on a base and an outer branch suspended from the inner branch by an articulation assembly. The articulation assembly enables rotation of the outer branch around vertical and horizontal axes and is positioned between first and second ends of the outer branch. The first end is provided with a counterweight for balancing parts of the outer branch that are situated on opposite sides of the horizontal rotational axis. The arm also has a disengageable device for actuating the rotations of the outer branch around the horizontal and vertical axes and a flexible link which suspends the pipe, upstream of the device, from the second end of the outer branch.

Abstract: The invention provides a balanced arm (201) for transferring a fluid product, having a transfer compass comprising an inner transfer member (208) and an outer transfer member (221), articulated together, and a counterweight system (203) for balancing the transfer compass, characterized in that the compass is installed on a turntable (215) rotatable about a vertical axis, to rotationally drive the transfer compass about that axis, and the balancing system comprises at least one counterweight (207; 207?) mounted so as to be able to turn about an axis (206) of horizontal general orientation, on a support (251) fixed to the turntable and functionally linked to the inner transfer member to provide the balancing of the transfer compass.

Abstract: 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.
