Primitive techniques back in ancient Egyptian cultures used log rollers, greased logs, ropes, and droves of manual labor. Bouyancy in ships made of reeds and grass were loaded with sand to lower a boat in the water. Stones were rolled on, and then sand emptied out to make the boat float. Sand piles, and smaller stone wedges were used in conjunction with the physics of a Fulcrum, in order to use a stone's own weight to stand it upright (for pillars and columns). "Block and Tackle" was the next mechanical evolvement (use of pulleys) to lift objects. Lifting technology really didn't emerge until the start of the Industrial Revolution in approximately 1812. Incremental stages that increased productivity were Steam Engines, followed by the Combustion Engine, followed by Hydraulics and Electrical Motors, and now magnetic levitation is a science incorporated into the newest high-speed trains.
