To lift a piano to the top of a building, a pulley system would be the most effective simple machine. Pulleys can reduce the amount of force needed to lift heavy objects by distributing the weight and allowing for easier lifting with less effort. By using multiple pulleys in a block and tackle configuration, you can significantly decrease the force required to raise the piano safely to the desired height.
