ABSTRACT:
A piano truck has a supporting structure comprising four elongated supports interconnected to form an adjustable parallelogram-shaped frame on which the piano can be supported. A wheel is mounted on each of the four supports so that no two wheels are colinear. The truck is compact and lightweight so that the piano can easily be maneuvered and transported through narrow doorways. Members are provided for fixedly attaching the supporting structure to a piano to avoid tipping over of the piano.
