While some quarrymen would have been stationed above the blocks, hauling them upwards directly, others would have stood below the blocks, pulling downwards. Their ropes would have been lashed round the post holes and attached to the alabaster blocks, so that both groups were exerting force to pull the blocks up out of the quarry.

This stone haulage system makes efficient use of the limited available space on the ramp, and it is reasonable to speculate that this same pulley technology would also have been used in the construction of the Great Pyramid. While pulley systems are well known from Greek civilisation in the first millennium BC, the evidence from Hatnub pushes their use much further back in time, as it pre-dates the Greek evidence by some 2,000 years.

The Hatnub haulage ramp is also much steeper than most previous reconstructions of Egyptian haulage ramps. This is significant because one of the long-standing objections to the theory that the Great Pyramid was build using a single large ramp was the enormous volume of such a ramp (which would have had a greater volume than the Great Pyramid itself). With a much steeper gradient, the length and volume of such a haulage ramp would be much smaller, suggesting that this old theory needs to be re-evaluated more seriously.

Many other theories have previously been proposed for how the Great Pyramid was constructed. For example, a ramp might have coiled around the sides of the pyramid. There are also many suggestions involving levers and similar mechanisms. (And, of course, there are always those lacking in imagination who cannot accept a human explanation, and instead groundlessly evoke aliens or Atlanteans). The merit of our recent discoveries is that they give us solid archaeological evidence we can use to test previous theories.
