Abstract
A grouping head hoist uses a plurality of conical couplers mounted upon cables to rearrange and lift a plurality of projectiles. The couplers are locked to the eyelet at the nose of the projectiles and the cables are raised relative to a lower guide plate such that the couplers will seat within corresponding conical holes within the guide plate. The positioning of the holes in the guide plate determines the structure of the array into which the projectiles are rearranged. An upper support plate disposed above the guide plate raises and lowers the cables by operation of hydraulic cylinders connecting the upper support plate and lower guide plate. Alternately, the cables may be reeled upon reels or drums mounted within a case. An automatic release plate is used to simultaneously release numerous of the projectiles. A turn counting mechanism limits rotation of the reels upon which the cables are wound. A scissors mechanism or linkage assembly is used to stabilize the hoist.
