<p>A refuelling system is provided, the system comprising: a plurality of vertically telescoping elements, the telescoping elements containing a constant length of flexible conduit for transfer of fuel; at least one vertically movable pulley to maintain a constant length of flexible hose within the telescoping elements; an overhead gantry capable of moving the vertically telescoping elements in two horizontal essentially perpendicular axes; and a rotating lower portion of the telescoping elements capable of rotating about an essentially vertical axis and supporting a fuel nozzle. The refuelling system of the present invention does not result in significant segments of unsupported lengths of conduits for fuel, compressed air, vapor recovery, electrical power or control or sensor signals. It is relatively simple and utilizes readily available components and parts, and does not required significant machining of components. This results in an installation that is economical to install and operate.</p> |
