Abstract
A machine is described for accurately elevating and aligning large ceiling panels for placement in an overhead ceiling. The machine includes a frame supported by wheels which permit horizontal transport of the machine between panel receiving and panel placing positions. Elevating outriggers are provided to elevate the frame and wheels at the panel placing location and to partially advance the panel vertically toward placement. A series of elevating stages which are slidably mounted upon guides fixed to the frame elevate the panel to its final elevation for placement. Hydraulic cylinders are provided to elevate the stages. A pair of carriages are provided, mounted on the elevating stages, slidably adjustable along stage frame members, for shifting the panel into transverse and longitudinal alignment for placement. An upper carriage includes a turntable bearing upon which is mounted a base for supporting the panel. Hydraulic motors cause the inner race of the turntable bearing to which the panel-supporting base is fixed to rotate about a vertical axis with respect to the machine, providing angular alignment of the panel for placement. The panel placing machine is particularly suitabl…
