What Is A SLED And How Is It Used In Traffic Control?

SLED for rent or sale traffic control from capitol barricade

Most people recognize orange cones, barrels, and water-filled barriers on the road. The SLED is less familiar. But if you work in construction, road maintenance, or traffic management, it belongs in your toolkit.

A SLED is a longitudinal energy dissipater sled. It serves as a crash cushion at the exposed end of barriers in active work zones. We carry SLEDs for both sale and rent to fit any size project.

What A SLED Does In The Field

A SLED functions as a redirective gating crash cushion at the end of barrier lines. When an errant vehicle drifts out of its lane toward a barrier end, the SLED takes the hit. The sled’s unique design incorporates four internal steel cables that envelop the impacting vehicle. Those internal steel cables absorb and redirect energy during the crash. The result is a complete crash cushion effect that virtually eliminates vaulting.

The SLED is MASH tested and carries tested, passed, and eligible status under current federal guidelines. It is FHWA accepted for shielding the blunt end of concrete, steel, and water filled barriers. It supports uni and bi directional use, making it a reliable non redirective gating crash cushion for a range of site configurations.

Where A SLED Can Be Installed?

A SLED installs on a road or bridge deck without requiring foundation anchor bolts. Workers can place it on compacted dirt, gravel, decomposed granite, asphalt, or concrete surfaces. That flexibility makes it one of the most versatile transition products available for traffic control today.

The SLED works with both permanent and temporary portable barriers. It handles temporary portable barrier shapes including concrete, steel, and plastic systems. Its narrow footprint makes it a practical choice where minimal shoulder spacing limits your options. Standard transition panels manage converging or diverging angles with no special hardware needed.

Because the SLED does not require foundation anchoring, crews cut down installation exposure time on the road. Less time setting up means a lower possibility of secondary accidents for your workers and the traveling public.

How Is A SLED Is Built?

Each sled module is manufactured from high visibility yellow polyethylene. The material is UV stabilized to minimize degradation from sun and long-term weather exposure. Water filled barriers connect quickly to each module for fast deployment. Fill indicators confirm that barriers are properly filled to FHWA accepted levels before the site opens.

The sled’s stout design is available in multiple sizes to match the barrier system in use. Its limited gating system works to envelop the impacting vehicle and absorb impact energy. A pickup truck or larger vehicle impact is handled effectively by this design. The SLED is a narrow, low-profile unit that crews install quickly with an easy set up process.

Using The SLED As An End Treatment

A sled end treatment replaces heavier systems that require foundation anchor bolts and longer setup windows. The sentry longitudinal energy dissipater design keeps the overall footprint small without giving up crash performance. Crews set it up at the end of concrete, steel, and water filled barrier lines in work zones large and small.

This product works as a non redirective crash cushion in most standard work zone layouts. It also performs as a redirective gating crash cushion where site geometry calls for it. The sled incorporates a design built to protect workers on compacted dirt, gravel, decomposed granite, asphalt, or concrete surfaces.
