The Egyptian Pulley is a two component, true pulley fabricated from high compressive strength materials (well known in the Old Kingdom) and is a simple mechanism that the Old Kingdom Egyptians could have employed to lift the 2.3 million Great Pyramid stones. The Pulley has been successfully demonstrated full scale. Evidence of use of the Egyptian Pulley design exists in the Great Pyramid itself.
