ABSTRACT:
A crane-like apparatus for enabling easy assembly and easy lifting from a horizontal to a vertical position of a structure. The apparatus comprises two (or more) clamping arms attached to the pivotally mounted mast of the apparatus with clamping means mounted on clamping arms at selective positions along the lengths thereof, such as by providing a plurality of spaced holes through which mounting bolts may be selectively fastened. The clamping means comprises a hydraulic cylinder on one end of the clamping arms and either another hydraulic cylinder, or a dummy cylinder or stop, on the other end so that the structure to be assembled may be clamped therebetween by application of hydraulic fluid to the cylinder, thus not marring the surface of the structure. Thus, the structure can be assembled while clamped in the horizontal position of the mast to enable easy reach and assembly; and thereafter, clamped by the hydraulic means and lifted to a vertical position so that it can be wheeled to any desired location for vertical mounting.
