Trench Shoring and Shielding Showcase

Since 1989, Efficiency Production’s Build-A-Box has been the industry’s standard modular aluminum trench shield system. The company’s Build-A-Box can be assembled in minutes to a wide variety of two-, three- or four-sided configurations. This flexibility enables work crews to make on-the-spot design changes to meet job requirements in conditions ranging from light to extreme.

National Trench Safety

The National Trench Safety “Work Zone Safety System” is a fully integrated, engineeredsolution to address today’s underground contractors need for a product or products toprotect workers and the public in and around an excavation. The NTS Handrail Systemis specifically designed to attach to most trench shield panels, slide rail panels and orvarious other forms of excavation protective systems to provide a continuous barrieralong the excavation wall. The NTS Ladder Access Platform maintains the barrierbenefits found with the NTS Handrail System and provides an access and egress pointthat does not compromise the fall protection provided by the handrail system. The NTSDavit Arm System is the final component of the fully integrated NTS Work Zone SafetySystem, which was designed so that it could be easily repositioned and the wide rangeof motion provided by the articulating davit arm helps to minimize the frequency ofrepositioning.

Mabey

Mabey Inc.’s sheet-and-frame shoring is a flexible, easy-to-install, engineered system thatallows contractors to create safe excavations in almost any soil conditions. Mabey sheet pilingcomes in a variety of lengths and profiles that allow for job-specific designs. Sheets are drivento the desired depth using Mabey’s excavator-mounted vibratory hammer (EMV), giving thecontractor the ability to self-install sheet piling using only the machinery already on site. Providingstrength and safety to the system is Mabey’s hydraulic frame system, which installs easily withno cutting or welding required. Hydraulics hold the frame safely in place, and when the job isover, the frames are simply retracted and removed. Mabey’s engineers can design a sheet-andframesystem to support excavations of almost any size and shape. For more information, visitwww.mabey.com.

Cerda

The G-1 and G-2 Guide frames by Cerda Industries are an innovative hybridalternative to the dated slide rail system. This versatile system can be used in alltypes of open pit sizes up to 50X50X30 ft deep, as well as all linear applications. Sincethe sheeting frames are non-vibratory, they can be installed by over excavating andpushing the sheet down the guided track as you dig. At 20-ft depths, each sheetonly needs to be towed in a minimum of 2 ft and no additional whaler is requiredas in other similar systems. This important feature results in more cost-effectivesavings on man hours and size of excavator needed for installation and removal.For more information, visit www.cerdaindustries.com.
