Abstract: A vertical lifting device is provided to enable a single operator to lift and place materials, particularly where materials such as kitchen cabinets are to be installed along vertical walls or in vertical corners. Telescoping vertical columns enable a gross height to be pre-set and a pivoting mechanism produces both vertical and lateral positioning for final placement by one person. The pivoting mechanism may be frictionally locked at the desired placement position to free the single operator to thereafter secure the material being installed. A variety of support platform designs may be provided compatible with the installation surfaces. Pivoting supports are provided to enable folding of the device for compact transportation and storage.
