A gate moving mechanism is supported by the pallet base and configured to engage the moveable gate assembly when the full shipping container is positioned onto the pallet base. A material director has a first end located beneath the pallet base subjacent of the gate moving mechanism. The material director extends downwardly from the pallet base and terminates at a second end opposite the first end. Bulk material is dispensed from the shipping container into the first end and is discharged from the second end of the material director.
