ABSTRACT:
A lifting and telescoping dolly for facilitating the moving of bulky objects into and out of attics by one operator acting alone. The collapsible dolly opens into a self-supporting A-frame with four support points. It has wheels and a brake system for positioning the dolly beneath an attic entry. From ground level a winch elevates the telescoping upper part of the dolly frame into the attic where it is firmly supported. From the attic a second winch elevates the load into the attic.
