ABSTRACT:
A lift dolly is comprised of a first castor-based platform and a second castor-based platform. Each platform is secured to an object to be lifted such that when so secured, the first platform extends diagonally upwardly and the second platform extends diagonally upwardly and terminates below the first platform. Downward articulation of the first platform causes lever lifting of its end of the object and also engages and causes downward articulation of the second platform which lever lifts its end of the object. Through continued lifting the lever fulcrum moves toward center increasing the mechanical advantage of the device.
