The 4400 Barrier Machine features a new frame design for right- and left-side slipforming. The Glide Control console slides side-to-side for better operator control and visibility of the paving operation. A mold mounting system can provide molds up to 39.4 in. on either side of the machine. A side mount is available for larger barriers. It also includes a new auger providing the pitch and speed designed specifically for transporting low slump concrete.
