Abstract: An insulated roof structure includes insulating thermal elements which space attachment clips from an underlying purlin and introduce substantial thermal resistance above the purlin. Each insulating element includes a metal cap and an insulating body portion. The cap is enlarged at one end to overlappingly receive the end of an adjacent insulating block. And, the cap has a positioning device that aids accurate positioning of the overlying roof panels.

Abstract: A crane structure mounted on a transport vehicle, preferably a marine vessel, is disclosed. The crane structure includes a gantry structure mounted on a vertical tower structure and having boom portions protruding from the tower structure. Preferably, the boom portions may be pivotally lowered from their operating positions and the tower structure may be rotated in a horizontal plane, thereby reducing the overall dimensions of the crane structure to allow transport under overhead obstructions and through narrow passageways.

Abstract: An apparatus and method for covering the ridge or peak of a metalroof system is disclosed. After the metal roofing panels are set in place on the sloping surfaces of the roof and seamed together, mating halves of a ridge panel are positioned along the ridge and parallel thereto. The mating halves have cut-outs corresponding to the rib seams of the roofing panels, the cut-outs each being covered by a seam cap. After the ridge panel halves are secured to the roofing panels, the interlocking joint between them is folded over and permanently seamed together. Finally, the areas at the ends of the ridge adjacent the rakes of the building are covered by filler panels. The filler panels have cut-outs corresponding to the rib seam of the ridge panel, and the cut-outs are similarly covered by seam caps.
