One embodiment provides for a material reclaiming apparatus for use with a bulk storage bin. The bulk storage bin includes a bottom which defines an elongated plurality of outlet openings from the storage bin. The material reclaiming apparatus includes a plurality of gates. Each gate is associated with a respective outlet opening, and each gate is moveable from a first position (blocking the associated outlet opening) , to a second position (not blocking the associated outlet opening). The material reclaiming apparatus further includes a traveling reclaimer located beneath the bottom of the bulk storage bin, and which is configured to travel along the bottom beneath the gates. The traveling reclaimer includes a gate actuator. As a result of positioning the traveling reclaimer under any given gate, the gate actuator engages the gate to allow the gate actuator to move the gate from the first position to the second position.
