I like it! Pivots would do well also, using almost half the weight to assist in raising and pivoting the other half. I never bought into the long earthen ramps anyway.
The "arc of wood" would have "heels" where pivoting could occur.
The ropes would fit in twin channels with a simple pass-around. A small crew would maintain tension in the reverse direction, while a team of men would pull at the top of the wheel shaped cargo load.
At the final position, they would remove a couple of arc-shaped skids, and tilt the stone into its final position.
Then they would gather up the materials and head back for another stone.
The construction teams competed with each other, as sports teams do today.
