For a piano, a cracked plate (harp) is a fatal injury. The most likely cause for cracking a plate is dropping the piano while moving it. Merely moving it a couple of inches can send it crashing into the floor if a leg has a frozen castor, stripped screws, or cracked locking plate. I've discovered that inserting your foot under the falling instrument will protect both it and the floor from harm, but I don't recommend it if you value your toes.

For all you would-be piano movers, test all three legs before moving it, and assume a leg WILL collapse so you won't get caught off guard if it happens!
