ABSTRACT:
Large storage tanks are lifted by means of pressurized bags and support members. Tanks may easily and quickly be lifted for inspection, repair and reconstruction. Lifting the tank allows for visual inspection under the tank for corrosion to prevent leakage of environmentally hazardous chemicals stored in the tank. The lifting bags are placed under the tank, inflated, and support timbers placed under the raised tank. The bags are then deflated allowing the tank to rest on the support timbers. The deflated bags are raised by placing support timbers under the bags. The bags are again pressurized further raising the tank. The steps are repeated until the tank is lifted to the desired height. Bags may also be placed under the floor after the wall or rim of the tank is lifted. This does not require cutting holes or welding of supports on the wall or floor. Ground suction is broken by raising one side of the tank with the lifting bags, placing supports as far as possible under the tank rim and depressurizing the bags to rock the other side of the tank off the ground. A fulcrum method is also applied to use the partial weight of the tank as a leverage force to alternately raise opposite sides of the tank.
