Sled Impact Attenuators

The Sentry Longitudinal Energy Dissipater (SLED) is a narrow, non-redirective gating crash cushion. SLED is designed to shield the end of all permanent and temporary portable barrier shapes including concrete, steel and plastic. SLED's unique design incorporates four internal steel cables which help envelop the impacting vehicle, reducing the possibility of secondary accidents. The SLED End Treatment does not require foundation anchor bolts to be attached to the road or bridge deck. The complete crash cushion can be installed quickly, with as little as one pick up truck and two workers on compacted dirt, gravel, decomposed granite, asphalt or concrete.

• MASH eligible for shielding the blunt end of concrete

• NCHRP-350 Accepted for shielding the blunt end of concrete, steel or water filler barriers

• Quick and easy set-up, no foundation anchoring, minimal installation exposure time

• Cost effective end treatment for concrete, steel or water filled barriers

• Universal transition quickly and easily attached to a variety of barrier shapes and sizes

• SLED’s stout design virtually eliminates vaulting

• Narrow footprint is ideal for work zones or roads with minimal shoulder spacing

• Shortest length TL-3 Water filled crash cushion, fewer incident impacts

• Containment impact SLED minimizes debris field

• Visual “drive by” fill indicators quickly verify water modules are properly filled

• Accepted for use in uni- and bi-directional applications

• Internal steel cables help envelop vehicle after an impact, creating a truly “limited gating” system

Big Sandy Crash Barrels

"Big Sandy" Crash Barrels are impact attenuator sand barrels.  They are certified to meet the crashworthy requirements of NCHRP 350.

Impact Attenuator Sand Barrels

• Big Sandy is identical and unchanged as a crash cushion when meeting NCHRP 350, TL-3 and MASH eligible.

• Plastic barrels are engineered to break upon impact, resulting in proper attenuation of the impacting vehicle

• Three (3) barrels are used to create all weights required in current standard array plans

• Combination barrel utilizes a pedestal base and 200, 400, 700 lbs top half barrel to obtain weights without using shelves or cone inserts - eliminates leaking sand

• Simple fill barrel to the molded-in fill line to obtain the correct weight. The molded-in fill line makes external verification of weights easy

• Reinforced lip prevents barrels from deforming when filled and provides a quick and secure lid fit

• Big Sandy’s stout construction allows for easy moving, lifting and emptying with optional TrafFix Lifting Ring
