Abstract
Abstract A method and apparatus for cradling a tank wherein the latter is constantly held in cushioned, spaced relationship with U-shaped framework of the cradle. The tank is cradled by filling the space between the tank and the framework with an initially fluid, resinous substance which bonds with the framework and the tank as the substance cures to a solid, resilient state. Upon curing, the tank and cradle are integrally bonded into a single composite unit wherein the resinous substance cushions the tank away from the framework to distribute the load evenly over the surface of the tank. A protective, fiber glass sheath enclosing the cradle is bonded to the tank.
