To move a piano, you need a wheeled furniture dolly, sturdy moving straps, a large transport truck with a ramp and several strong friends. Begin by closing and locking the keyboard lid to minimize possible damage to the keys during transportation.
Wrap the piano in padding or blankets to prevent scratching the finish, then secure with tape. Keep the piano in the upright position, and place moving straps under the body. Use the straps to lift the piano from underneath, and position it on the furniture dolly. This step requires at least four people.
Plan your route through doors in advance. Move the dolly slowly and deliberately toward the doorway, and stop every few feet to adjust your grip, if necessary. Have the ramp in place and the doors of your moving van open and ready so that you can slide the piano into place. Position the piano against the back wall of the van for stability during the move.
