Aluminum hydraulic shields consist of lightweight, aluminum side walls, coupled with heavy-duty hydraulic struts. The strut contains a hydraulic cylinder and return spring, and is protected by steel box tubing. A uniquely designed manifold allows the user to precisely control the flow of fluid to each cylinder, while safely outside the trench. This makes hydraulic shields ideal for irregular size excavations. The shields may be used in a hydraulic mode, providing pressure on the sides of the trench, or in a static mode – much like a standard trench shield. Because of their lightweight and easy assembly, these shields can be handled easily by rubber-tired backhoes. They are ideal for municipal maintenance or repair projects, utility or cable work, and light to moderate duty general underground contracting.
