Abstract
Abstract An unloader for portable containers including tension hanger arms suspending a vibratory support from a fixed support and pivotally connected to each support to limit the vibratory motion to horizontal, reciprocal, rectilinear motion. For side outlet portable containers, the vibratory support includes a first frame portion inclined relative to the horizontal and a second frame portion, with a discharge orifice, extending perpendicular from the lower horizontal edge of the first frame portion.
