ABSTRACT:
The present invention relates to a method and apparatus for dumping the contents of a container. A container dumping apparatus according to the present invention includes a frame and a carrier positioned on the frame for movement relative to the frame. The carrier includes an arrangement for supporting the container to be dumped. An actuating device for moving the carrier between rest and final dumping positions includes a first tilting arrangement having a first portion and a second portion extensible/retractable relative to the first portion. At least one cable is anchored at an outer end to the carrier and at an inner end to the first portion of the first tilting arrangement. The extensible/retractable second portion of the first tilting arrangement is arranged to act upon the cable intermediate the anchored ends thereof to shorten the span of the cable extending between the carrier and the extensible/retractable second portion. The shortening of the span of the cable causes at least a portion of the carrier to raise and thereby tilt the container to an intermediate position between the rest and final dumping positions. A second tilting arrangement is connected to the first portion of the first tilting arrangement to displace the first portion for further tilting of the container to the final dumping position.
