ABSTRACT:
A hand operated, vertical lift dolly upon which objects may be placed and vertically lifted or lowered using the mechanical motion of a load handle. A load table is controlled by the load handle, and can be locked in place once it has been raised to a transport configuration. The load table remains in a substantially horizontal orientation throughout the loading and lifting process. The dolly can be moved from one location to another for loading and unloading objects, this motion facilitated by a wheeled carriage. The vertical lift dolly can, by appropriate positioning of the handle and load table, be placed in a space saving storage configuration.
