Abstract

A system includes a plurality of lifts configured to couple to a storage tank about the storage tank, a reservoir to store compressed air, and a manifold. Each lift includes a hoist, a coupling to extend between the hoist and a roof of the storage tank, an inlet conduit to be coupled to an inlet of the hoist, and an outlet conduit to be coupled to an outlet of the hoist. A pressure difference between the inlet of the hoist and the outlet of the hoist spools the hoist. The manifold fluidly couples the reservoir to each inlet conduit and fluidly couples each outlet conduit to an exhaust. The manifold includes a plurality of outlet valves, each coupled to one outlet conduit of the plurality of outlet conduits and configured to regulate flow between the outlets of the plurality of hoists and the exhaust.
