Aluminum Trench Shields
National Trench Safety rents and sells a variety of aluminum trench shields to meet specific project needs. Our aluminum shield lineup includes Lite Guard Aluminum Shields, Corrugated Wall Aluminum Shields and Smooth Wall Aluminum Shields. Each aluminum trench shield has unique design characteristics that affect its performance and strengths.
Lite Guard TM Aluminum Trench Shield
The Lite Guard™ Aluminum Trench Shield utilizes a patented, proprietary aluminum extrusion design to offer unparalleled strength from a lightweight aluminum shield. For example, a 6” wall 8’ x 24’ Lite Guard™ Aluminum Shield can achieve a depth rating of 8’ in C-80 soil while weighing approximately 7,345 lbs. The Lite Guard™ Aluminum Shield allows for lower lifting capacity requirements for machines on projects, which can help to reduce the fuel consumption on a project. Using the Lite Guard™ Aluminum Shield is also an eco-friendly alternative to conventional steel trench shields as the lighter machines lower emissions decreasing the carbon footprint on the project.
Lite Guard™ Aluminum Shields utilize adjustable spreaders to provide excavation support, while optional arch spreader kits are available to provide increased vertical clearance. Lite Guard™ Aluminum Shields are available in a range of sizes from 4’ to 8’ tall and 8’ to 24’ long.
The Lite Guard™ Aluminum Shield presents contractors with a versatile trench shield that has the ability to make a project more environmentally conscious by lowering machine requirements to lift trench safety equipment.
Corrugated Wall Aluminum Trench Shield
Corrugated wall aluminum shields are a lightweight alternative to steel trench shields. Corrugated wall aluminum shields are available in hydraulic and static configurations to suit a variety of needs. The shield’s panels are formed by attaching corrugated aluminum sheet to high strength aluminum walers for structural support. The distance from the bottom waler to the bottom edge of the shield typically provides about 2′ of vertical clearance.
Corrugated wall aluminum shields are most commonly 6′ or 8′ tall and 6′ to 12′ long, although custom sizes are available. Struts are available to provide excavations support from approximately 2′ to 12′ with manufactures tabulated data.
Smooth Wall Aluminum Trench Shield
Smooth wall aluminum shields build upon the design of the corrugated wall utilizing aluminum tube welded together vertically. Smooth wall aluminum shields are available in hydraulic and static configurations, with a hydraulic unit containing a manifold and lines run along the walers for hydraulic strut connection. Smooth wall shields are slightly heavier than the corrugated wall aluminum shield, however, provided increased vertical clearance to approximately 4’.
Smooth wall aluminum shields are most commonly 6′ or 8′ tall and 6′ to 12′ long, although custom sizes are available. Struts are available to provide excavations support from approximately 2′ to 12′ with manufactures tabulated data.
