Inty Shedu, the mythical Shedu, and the Shedu Pulley

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.
