Claims20
A bulk material shipping container unloader for a bulk material shipping container having a pallet, the unloader comprising:
- (a) a supporter having a plurality of legs;
- (b) a pallet receiver having a plurality of pallet support bases integrally connected to the supporter such that the plurality of legs extend downwardly therefrom, the plurality of support bases are configured to receive and support the pallet of the bulk material shipping container in an elevated position for placing full shipping containers onto the unloader and removing empty shipping containers from the unloader without disassembly thereof;
- (c) a material director having a first chute section supported by the pallet receiver and a second chute section connected to the first chute section extending downwardly from the pallet receiver;
- and
- (d) an automatic bulk material container gate mover supported by the pallet receiver, wherein the automatic bulk material container gate mover includes:
- (i) a track assembly connected to and supported by the pallet receiver;
- and
- (ii) a gate mover assembly supported by the track assembly for movement relative to the track assembly, the gate mover assembly having an upwardly extending member configured to receive and releasably engage a downwardly extending handle of a gate of a material unloading assembly of the bulk material shipping container.
