The present invention is a method for constructing cylindrical grain bins. The method employs a sets of identical, telescoping jacks actuated by hydraulic cylinders and an hydraulic system having separate hydraulic circuits that serve each set of jacks. Using the set of identical, hydraulic, telescoping jacks, successive rings of a grain bin structure made up of connected panels are lifted. After a first ring is lifted, a second ring can be attached to the lower edge of the first ring. The second ring is then lifted and the process is repeated until the grain bin is completed.
