Abstract
A grapple device (12) adapted for coupling to a conventional loader (110) is provided which is especially adapted for the pickup and handling of elongated auger sections. The device (12) includes a pair of pivotal arms (28,30) having auger-engaging pickup members (72,74) secured to the outermost ends thereof. The arms (28,30) are movable between a closed, auger-engaging position and an open position by a stationary piston and cylinder assembly (94) equipped with an extensible piston rod (96); the rod (96) is coupled to the arms (28, 30) by pivotal links (104,106). Selective rotation of the arms (28, 30) is effected by motor (108) coupled via chain (112) and sprockets (110,88) to the arm assembly.
