To build a Maya pyramid or other large structure was no easy task. It required a very large work force. Pulleys and wheels were, in all likelihood, not used, for the simple reason that they had not been invented, at least in the Maya neck of the world. The ancient Maya civilization was advanced enough to have a written language, yes, but no wheel.
Maya buildings were typically made from limestone, which was hauled to the building sites from local quarries. While in its bed limestone was soft enough to be chipped at even by stone tools. It was only when it was brought out and left in the sun that it hardened.
