Abstract
Abstract A telescopic boom assembly having stacked hydraulic hose structure disposed in configuration in the assembly and mounted for removal therefrom as a unit. The hose package is adapted for use on extensible boom structure having at least a pair of telescoping boom sections provided with a fluid-actuated extension cylinder and a source of pressurized fluid for operating the same. A plurality of elongated conduit means, each of which is provided with a fluid-conveying passage, are mechanically interconnected in vertically stacked relationship to present a continuous conduit assembly presenting a plurality of separate passages in superimposed relationship. The conduit assembly is constructed and arranged in the boom structure in disposition to prevent flexing thereof in a vertical plane, and clamp means readily accessible from one end of the boom structure secures the conduit assembly to the boom sections in a serpentine, closed loop configuration with the individual loops thereof lying in generally horizontal planes and confined by the sidewalls of a corresponding boom section to preclude kinking of the conduits during extension and retraction of the boom sections and consequent folding and unfolding of the looped portions of the conduits. Appropriate coupling means secure opposite ends of the conduits to the cylinder and the fluid source respectively. A second conduit assembly having a plurality of conduits presenting hydraulic fluid-conveying passages also disposed in vertically stacked, superimposed relationship is normally placed side-byside with the first conduit assembly to deliver fluid to the outer end of the outermost movable boom section for operating controls or power tools. The second conduit assembly is normally provided with at least four superimposed conduits disposed in vertically stacked, continuous, serpentine loop configuration and secured by appropriate clamps in the same manner as the firstmentioned conduit assembly.
