Quote:Ramps are generally considered to have been the main lifting devices for heavy material. While lifting devices such as pseudo pulleys and wooden levers were likely known in ancient Egypt, it has not been demonstrated that these tools could lift the massive stones of the great pyramids, which sometimes weighed as much as fifty or more tons.
Yet there are many different theories regarding what shape ramps may have taken, and there sometimes appears to be flaws in most any such design. However, today we know that ramps were definitely used at least in some pyramids, because we have discovered a number of ramps at various pyramid sites, along with some documentation that would suggest the use of ramps.
Jean-Philippe Lauer, a leading expert on the pyramids, provided a theory that seems to be acceptable, at least in part, to many Egyptologists. He suggests that both ramps and other lifting devices were used to build the Great Pyramid, which his theory specifically addresses. He believes that a whole system of ramps were utilized. These ramps would have been of various sizes and gradients. However, he also believes that additional tools and lifting devices would have been used, including wooden levers, round beams, poles and ropes.
