I think that the lyres on most pianos are strong enough for tilting the piano. Most of the movers I've dealt with use them. I would think that you would want to examine the lyre so that it is solid and attached well. Large and heavy pianos might be an exception. I've moved TOO many pianos. I now (if I can't get out of it) lift the bass end and tuck a 3 inch thick piece of expanded polyethylene under the lyre. This lifts the bass up enough to remove the bass leg. Now I position the skid on the dolly properly so that the bass edge tips on the center of the skid. The dolly will tip so that the left side of the piano will be flat on the skid until the piano is raised upright. The trick is to position the dolly so that the piano will balance. Now the piano can be centered and strapped down. An idea I got from Lowell Wacker (who moves pianos, any size, by himself is to brace the lyre to the treble leg. I made something for this out of threaded rod and plumbing parts. Haven't used it much but I think it would be some insurance against putting too much side thrust on the lyre. Anybody seen or heard of a lyre collapse? Picture of the contraption is attached. Carl Meyer Ptg assoc Santa Clara, Ca.
