Abstract
An apparatus for handling bulk materials includes a rigging frame which supports the upper end of the outer bag of an intermediate bulk carrier. A spool is rotatably mounted on the rigging frame and the inner bag of the intermediate bulk carrier is attached to the spool. The spool is rotated by a pneumatic cylinder thereby winding the inner bag onto the spool and emptying the inner bag.
