Abstract

A silo unloader is of the type which has three support arms, and three suspension cables connected to the support arms are trained over sheaves on a tripod in the top of the silo and connected to a winch on the outside of the silo wall by means of which the unloader is raised and lowered; and a filler spout is used for loading material into the top of the silo. The cable connection to one of the support arms is constructed to permit the point of attachment of the cable to be moved relative to the support arm so the unloader may occupy either a horizontal working position for unloading, or, an inclined position when it is raised for filling the silo; and in the inclined position the high side of the unloader is above the filler spout.
