An apparatus (10) for loading a transport container with a load of bulk material has a load bin (20) positioned for axial movement atop a base assembly (40). A packer blade (90) is positioned inside the load bin for movement relative to the load bin in the same axial direction. The load bin has an open first end (22) and a second end (24), with a pair of vertical side walls (66) and a substantially open top surface. Drivers (60, 92) are provided for the axial movements. Material is loaded into the load bin, the openable end of the transport container is placed around the first end of the load bin, and the load bin is extended into the transport container until the packer blade is inside the transport container. By retracting the load bin while retaining the packer blade inside the container, the load is transferred.
