About Paul Hai
2006 Paul Hai's Racks & Pinions theory. 1976 QLD State Honors in Motor-Mechanics. 2005 University of New England, Ancient History.

What follows has been known since 2006 via university research, however only Pravda in Moscow published the article titled "The Documented Ancient Construction Method of The Great Pyramid". Pravda placed the article on the London Global News Exchange in 2019 where it was ignored, or perhaps avoided.
Consider the movement of blocks in two ways ... Consecutively or Simultaneously and knowing the documented time-frame for the Great Pyramid is 20 years. Logistics of Engineering can only accommodate the SIMULTANEOUS movement of blocks which absolutely rules out consecutive and thus rules out ALL ramp and water shaft-canal theories.
The method used is known today as Rack & Pinion Mechanical Technology and the Egyptians developed its prototype at Giza. Those hundreds of limestone steps you observe for all Giza Pyramids are RACKS, over all four sides and height.
Inty Shedu was the carpenter in chief at Giza and fabricated LOBES made from short planks of Cedar which had been imported from Lebanon as we know via the "Palermo Stone". Evidence for the "four lobe pinion pulley" is the "Petrie rocker" excavated in 1895 by Edouard Neville and handed to Petrie in person for his London museum.
The Shedu four-lobe pinion-pulley is a machine of Class Two Lever Principle, Pivot-Load-Effort, same as a forward wheel, wheel-barrow, and has a mechanical advantage of 2.8 (MA=2.8) which means a 2500 kg Pyramid block can be raised with an input effort of 900 kg. Search haitheory
