Abstract
A cantilevering support arm is provided for supporting a suspended load and for encasing utility supply conduits to enable various activities requiring access to such utilities to be carried out at a distance from a structure supporting the arm. When used in association with welding operations for example, the arm may support a welding wire feeder, welding gun, and coil of consumable welding wire. A battery of utility outlets may be positioned at the outer end of the arm providing access to compressed air, fume and dust extraction, and electrical power. All utility conduits such as electric welding power supply conductors, air hoses, extraction ducts and electrical control conduits may be encased within the arm to protect them from damage, remove the hazard posed by conduits laying upon the shop floor and to provide for simple access to multiple utilities at a distance from the utility sources. The arm comprises an inner boom pivotally mounted to a stationary supporting structure, an outer jib, and a knuckle pivotally joining the boom and jib. The boom, jib and knuckle are operable in a horizontal plane to provide access to utility connections at the outer end of the jib within an …
