FEEDER OF HEAVY CARGO

PROBLEM TO BE SOLVED: To provide a feeder having a simple structure, capable of coping with a recess/projection of a heavy cargo by contacting with the heavy cargo by a large surface as much as possible, capable of reducing failure, being easy in correcting, adjusting and repairing a track for a movement and being excellent in workability. SOLUTION: An angle-shaped sliding part is formed on either one surface of an under surface of a crawler belt 23 and an upper surface of swinging bodies 47 arranged on a receiving stand 22, a V-shaped sliding groove is formed on either other surface to be slidable, the receiving stand 22 is installed on a sliding plate 21 via a longitudinal and lateral inclination adjusting means, the swinging bodies 47 are arranged at least by two pieces in a swinging body fitting groove formed on the receiving stand 22, these swinging bodies 47 are longitudinally swingingly fitted by a semicircular groove and a semicircular projecting streak part, and the sliding plate 21 is arranged on a pedestal 20 by interposing a horizontal direction adjusting means.
