A 28-page illustrated brochure, "Hydranautics Systems in Modern Shipbuilding," describes the company's three basic heavy-load moving systems — gripper jacks, Trans-Lifts, and chain jacks — and how they are used for mechanical translation in building docks, ship "extrusion" down slipways, launching onto floating drydocks, ship lifting, and constructing portable pontoon piers for cargo unloading. Photographs show actual field use of equipment, and drawings show sequence of operation.
