SEGMENTED EXTENDIBLE BOOM Abstract A longitudinally extendible, segmented boom structure includes a plurality of hollow, substantially V-shaped segments (10) which are pivotally connected to adjacent segments for storage. A series of load-bearing cables (134) extend through the segments for carrying loads. The segments have uniform cross-sections and progressively increasing lengths. Segments are stored in rolled-up form on a reel (12) by pivoting the segments to form a coil of nesting segments. Each segment has laterally extending side flanges (108) through which longitudi- nally extend the pre-tensioned load-bearing cables. The cables pass through the flanges on opposite sides of the boom segments for supporting vertical loads and resisting side loads on the boom. A second set of auxiliary cables (79) on the underside of the boom is automatically payed out as the boom is extended. The auxiliary cables prevent the extended segments from col- lapsing when inverted. The center point of the segment reel is adjusted in elevation to automatically feed boom segments at an optimum angle into a segment dispenser and boom support structure which has rollers thereupon for cooperating with corresponding lands and grooves on the segment flanges.
