Prater’s Theory of utilising comparatively flat, 2° ramps gives credibility in constructing the great pyramid, including building the relieving chambers.
In the early stages of constructing the pyramid, a good choice would be a 2-degree ramp. The incline, making it easier to move large, heavy stones.
A 2-degree incline is a very small gradient. The slope length is the same as its base length. Surprisingly enough, if this gradient spiralled up on the outside of the great pyramid, it would reach within 5-meters, from the top starting at ground level.
The spiral ramp could reach the very top of the pyramid by erecting a series of ramps above each other at the same distance, on the same footprint and before the incline meets with itself, later building the ramps closer to the centre of the pyramid, nearing the summit.
There is no other way to place the casings but to haul them up the outside of the pyramid. A spiral ramp constructed on the top of the casing stones would need to be filled in by starting at the bottom, making the ramps useless.
Blocks could also travel up the ramp, then get lowered down, onto the platform, before moving them off to the work area. It seems a slow way of building the pyramid, but would this matter to the men once that first block is on the ramp?
This gradient makes it easier for the men, which leaves a few other choices, such as using fewer numbers on each ramp section or moving more blocks at once.
Using 2-degree ramps on the internal structure makes sense when you look at the heavy blocks, such as those used in constructing the grand gallery and relieving chambers. On this gradient, cows could be handy. But really, there is no need for them?
The simplicity is in the build, using this gradient. The majority of the blocks are in the bottom third of the pyramid. There would be quite an expansive area on every course/level in this bottom section.
Utilising a 2-degree slope enables the block to leave the ramp at any location without too many difficulties. The gradient rises 0.035 mm in every metre. Roughly the width of two fingers together. Using smaller diameter rollers at these intersections, adjusted to suit the block’s level transit, would be easy, And are what I call platform rollers. (See: Bottom image on About Michael/Mike page).
Blocks could also travel up the ramp and then get lowered down onto it. After preparing the ramp for the next course, blocks move up it, then off to the work area. The gradient allows for the four corners and four sides to be worked on at the same time.
The image shows that a 2-degree ramp can be used on the structure, incorporating any large blocks, up to a height, well above the relieving chambers. These ramps are 10 metres in width.
Placing the Tura limestone casings first would involve using the outer spiral, which limits the blocks to one ramp, and one ramp width only. Not very good for a 25-year deadline, but possible to do so. Doing it like this would make it easier to keep dimensional control.
For me, it’s would be a good idea to place as many of the internal blocks as possible by using the ramps set on the structure.
A spiral ramp, would then be utilised for the casing stones and for bringing up the blocks that fit in-between the internal structure.
These blocks would be inserted between the line of casing stones previously placed.
After realising how many 2.5-tonne blocks could be hauled up the sides of the pyramid fast, at this moment in time, I am contemplating a few ways of constructing the pyramid. But one thing I am sure of, a small gradient would be essential for moving large, heavy blocks to height.
Testing the 2-degree ramp gradient proved how easy it is to move blocks for the pyramids.
