Abstract
The invention relates to a device for lifting and transporting heavy objects, such as a piano with the use of a hoist mechanism mounted on the frame which straddles the piano. The frame is mounted on casters to allow easy rolling of the frame along a horizontal surface, while the piano is being secured within the frame in a suspended position through the use of the lifting bar engaging the piano about its rear horizontal frame post. Pendulous movement of the piano is prevented by the use of a pair of horizontal cross bars secured to vertical posts of the frame in the lower and upper portions thereof.
