I'm not sure exactly what you are describing here, & why it would be different from a carpeted floor, but I always put a big wide nylon belt around the piano and tilter and ratchet the whole thing together so that wherever the piano and tilter go......they go as one piece! It only takes a minute to do and I sleep better at night - and no broken legs.
