Abstract
A piano lift and dolly has an upper H-frame that engages a piano and a lower H-frame that is supported on wheels. Four posts extend vertically upwardly from the lower H-frame and are received in downwardly extending tubes connected to the upper H-frame. A jack has its base mounted on a cross beam of the lower H-frame and its jack RAM mounted directly to a center point of the cross beam of the upper H-frame. Two beams of the upper H-frame engage the underside of the piano at different heights with respect to a floor on which the dolly is supported. As the jack is raised, the RAM raises the upper H-frame with respect to the lower one to lift a piano off of the floor. In this way, the piano is moved without the legs of the piano engaging the floor.
