Abstract
The invention is directed to a lifting device that can be used to lift, support and align articles such as cabinets, counter tops, shelving and the like during installation and removal. The lifting device includes a base, a hydraulic ram assembly, an adjustable L-shaped bracket assembly and an adjustable platform. The lifting device has a height adjustable range from thirteen inches to eight feet and is adapted to allow the load to be positioned directly over the lift or offset if an extended outward reach is needed. The adjustable platform is designed to allow the lifted article to be pivoted in multiple axes of rotation thereby allowing precision alignment of the cabinet with respect to the wall to which it is to be secured prior to installation.
