Abstract
An apparatus is provided for constructing cylindrical storage tanks from coiled strip steel. The apparatus carries and delivers the coiled strip steel circularly around the base of the tank. The strip steel is aligned and affixed with the overhead tank by a fitting frame provided behind the coil. The tank is thus constructed at ground level from a plurality of adjoined horizontal circular rings of strip steel. As each ring is completed it is progressively elevated on a support structure circularly arranged around the base of the tank. The apparatus includes a wheeled frame assembly, a turntable assembly rotatably mounted on the frame assembly, for vertically supporting the coiled strip steel, and a fitting frame mounted on the frame assembly and positioned to receive the strip steel from the turntable assembly. The fitting frame vertically guides the strip steel into alignment with the tank wall supported thereabove.
