Product Name: WideTRACC
Description:
The WideTRACC is essentially a modification of the original 6.4-m long TRACC crash cushion. Approximately 2.9 m from the nose, the side panels, connected to four progressively wider support frames, begin to flare outward at a seven-degree angle. Depending on the width and location of the shielded object, either one or both sides of the TRACC can be flared. The wider frames are anchored to the asphalt or concrete foundation with special low-profile anchors, and the side panels are bolted to the widened frames with special joint plates that establish the sevendegree flare angle between the frames and the panels. At this point, the WideTRACC is 1.47-m wide at the rear. If the shielded object is wider than 1.47 m, the seven-degree flare can be continued in 0.71 m increments. Each added increment of length adds 0.17 m to the width of the system. As an example (assuming both sides are flared), a 3.56 m extension would result in a rear width of 2.34 m and the WideTRACC unit would be 9.94-m long. The extended sections are comprised of two 10-gauge W-beam panels bolted to W150 x 13 steel posts that have C75 x 6 channel braces behind each post. The posts and braces are welded to a common base plate that is bolted to the foundation. When the extension transitions to a rigid concrete wall, a C200 x 17 steel channel must be used between the lower W-beam and the braced support posts.
