Abstract
An apparatus for repositioning a piano between a horizontal orientation and a vertical orientation, and for moving the piano along a surface while in the vertical orientation. The apparatus comprises a base assembly, a cradle assembly, and a repositioning assembly. The base assembly provides a framework for connecting the cradle assembly to the repositioning assembly. The cradle assembly engages and supports the piano. The repositioning assembly moves the cradle assembly between a horizontal and a vertical position.

An apparatus for repositioning a piano between a first position and a second position comprising:
- a base assembly comprising:
- a base frame comprising a first frame rail, a second frame rail, and a pair of outside frame legs connecting the first and the second frame rails in a rectangular configuration, and an inside frame leg connecting the first and the second frame rails;
- a piston attached to the base frame;
- and
- a vertical frame extending approximately perpendicularly upward from the base frame, the vertical frame comprising a pair of vertical frame rails extending perpendicularly upward from the inside frame leg and one of the outside frame legs, and a vertical cross frame rail connecting the pair of vertical frame rails;
- and
- a cradle assembly for receiving a piano;
- and
- a repositioning assembly comprising:
- a cylinder top beam positioning element pivotally connected to the vertical frame and fixedly attached to the cradle assembly;
- a cylinder top beam attached to the cylinder top beam positioning element and the piston;
- and
- a torque tube element moveably connecting the cylinder top beam positioning element to the vertical frame.
