I agree, hire an INSURED furniture mover, a piano mover for something huge needing care.
IF a friend unable to help had a brother, son, etc, that might work.
Coincidentally, looking for powerful amp/mono blocks: I thought, the front handles can help when repositioning something already in place, but nearly worthless lifting/putting in place.
Also, in-place, access to in/out connectors must be solved safely.
