How ancient Egyptians built the 4,500-year-old Great pyramid (Kufo Pyramid), at Giza Plateau? No definite answer for this question, which attracted the attention of travelers, historians, philosophers, researchers as well as, volunteers since ancient time, has yet been introduced. No definite answer has been introduced for the question how ancient Egyptians lift such huge stones up to the top of the pyramid (146 m height)? Hundred hypotheses have been suggested to explain how these stones were raised to such highest. The theories that call attention to external straight or spiral ramps corkscrewing around the sides of the pyramid, haul up the stonework are the most acceptable ones between Egyptologists. However, these theories are also criticized by Egyptologists, e.g. “Pop Brier” said to the Media [1]: « I’ve been teaching them myself for 20 years but deep down I know they’re wrong ».

The first radical theory in this concern was presented by Hasan Sayid Ahmad, an Egyptian citizen, more than ten years ago. In his theory Mr. Ahmad announced that lifting the pyramid stone blocks were done through the ascending passage inside the pyramid itself. Accordingly, he considers this passage to represent internal ramp. The stone blocks were raised up by using semi mechanical transformed machines (called them “elevators”) inside the Great Pyramid, designed by ancient Egyptians to lift the stones of the pyramid. Mr. Ahmad paid a considerable attention to one of them that was working in the ascending passage including the grand gallery of the pyramid. Such machine (elevator) was in the form of two wood sledges attaching each other along a complicated system of ropes, one of them moved in the descending passage (referred here as lower sledge) and the second moved in the ascending passage with the grand gallery (referred here as upper sledge). Few persons controlled the movements of this machine (see attaching sketch). Down sliding of the lower sledge pulled up the upper sledge, whereas, down sliding of the upper sledge pulled up the lower sledge. Mr. Ahmad sees that the machine was used first to lift 2.300.000 stone blocks representing the whole stone blocks of the Great Pyramid, and later on it was used for the movements of the persists inside the pyramid [2]. To support his view, Hasan designed a complicated model showing the work of such machine and described in detailed each part.

However, this hypothesis shows that the pyramid was built using internal ramp via the ascending passage. Accordingly, after the first few rows of stone blocks, ancient Egyptians started to transport stones via the ascending passage which represented internal ramp. Mr. Ahmed thinks that the ascending passage was wider during the work years to allow easily movement of the stone blocks. He adds that there was no other usage of the descending and ascending passages accept that purpose, judging from their shapes and sizes. He denies the possibility that they were used as normal passages. To support his few he called attention to their smooth surfaces which impede people to move via them easily.

Mr. Ahmad stated that there was a second similar sledges inside the pyramid, starting from the upper end of the grand gallery, giving no detail on such sledges. To document his achievements, Mr. Ahmad introduced copies of his new idea accompanied with many illustrations accompanying each part of the sledges, including the ropes, for many authorities in Cairo.

However, Mr. Ahmad theory re-energized after the French architect Jean-Pierre Houdin claimed that the pyramid was built from the inside out, calling attention to internal spiral ramp, used to lift the stones of the Great Pyramid. Mr. Houdin new theory meet nearly a wide acceptance of Egyptologists, e.g. “Pop Brier” consider it as a valid theory against the other theories [3]. Mr. Houdin probably studied Hasan’s theory, but he did not refer to it in his publications. However, these words: “the Grand Gallery inside the pyramid, another source of mystery for Egyptologists, housed a giant counter-weight used to hoist five 60 ton granite beams into position above the King’s Chamber”, in Mr. Houdin’s report [1] indicate that he studied Hasan’s report.
