Please go back and read. I rarely make derogative remarks, such as... "You really are too much", and/or you must be smoking dope.
My answer to your question was positive, ie. "Yes they could.
They may have a big issue, if you are thinking of Houdin's interior spiral. I have studied his proposal and methods, and it is full of inappropriate, in the real world, mechanical errors. I measured his proposed tunnel width. He does not provide enough room to have workers and empty sleds to make their way back down. They would have to be crawling over the stones, or use some other hidden passageway, as once suggested, once he realized the same... His stupid lift system with a counter weight is additionally laughable. Why, because the energy required to pull the counter weight up to a higher elevation, could simply be put into pulling the weight up, in the first place. You gain nothing. I use a counter balance in my illustration, which is not the same as employing a counter weight. It only zero's out the weight, such a balance scale.
Here are a few other alternatives."
My drawings which started this thread, show no ramps that could be used, to walk down on. This is because, you have at your disposal a lift system. An Elevator. With that system at the current build stage shown in my illustration, it would take less than one minute to reach the top. It is functional in both directions. They likely used several such lifts. If you are of the camp, those 30 foot walls surrounding the Pyramids, were used to hold water, well that is even better.
They used a water slide. Well, at least those who could swim.
I find it useful to have a bit of humor on GH. It helps keep one saine?
