What is the "Egyptian Pulley"?
- The Old Kingdom Egyptians obviously used some kind of rudimentary but powerful "lifting machine" - one they could have readily fabricated based on available materials and known skills.
- The Egyptian Pulley is a simple but true pulley - a lifting machine.
- It is proposed that the Old Kingdom Egyptians, builders of the Great Pyramid, used such a simple, robust pulley to both move and lift the Pyramid's 2.3 million stone blocks.
- Provides the solution to how one stone was lifted every five minutes for ~ thirty years -- and this is the major challenge almost all theories simply ignore.
- Engineering calculations prove that there was sufficient area for the number of rope pullers required.
- Full scale experiments have successfully demonstrated the operation of the Pulley.
- Evidence supportive of the Egyptian Pulley exists in the Great Pyramid itself.
- The recent discovery of a steep ramp in the Eastern Desert of Egypt proves that the Old Kingdom Egyptians utilized steep ramps to lift heavy stones. And steep ramps necessitate the use of a rope direction changing mechanism -- a true pulley being the most efficient.
