Hydraulic Trench Shields consist of lightweight,
aluminum sidewalls, 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 trench shields ideal for irregular size
excavations.
The trench shields may be used in a hydraulic mode,
providing full pressure on the sides of the trench, or in a static mode --
much like a standard trench shield.
Because of their light weight 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.
