It seems to me you were asking how to box up a heavy component, and lifting a heavy component into a box is awkward. The easiest way that I am aware of is to leave the component on the floor; put the open box over the component, so that the component is now in the box, but you cannot close it because it is all upside down; then reach under the component and tip the whole thing up on its side and then over so it is flat on the floor again but now upright; close the box and tape it - et voila! A variation to this is to have tipped the component over onto its back first so that the end result is right side up, but this is only necessary with certain components and requires you to get your hands under the upturned component and so may require a couple of wood blocks to be used.
