ABSTRACT:
An apparatus facilitating the lifting and movement of objects. The present invention, in one embodiment, features a curved rim extending around a mounting plate to which an object or an object carrier can be attached. The object is mounted off-center relative to the central axis of the curved rim. According to the invention, a counter-balancing weight offsets the moment associated with the object to allow the moving device to roll along a surface, and thereby move the object, with application of a small amount of force. According to embodiments of the present invention, the curved rims include at least one section having an increased radius of curvature relative to other sections of the curved rim to promote rotation of the moving device.
