Temporary mechanical attenuators are one of the best ways to protect the motoring public from the blunt end concrete barrier as well as hazards like overhead sign structures, bridge abutments and piers and toll booths. temporary mechanical attenuators act as a temporary barrier can be used where an attenuator with a narrow footprint is required. Temporary mechanical attenuators can be used in both re-directive and non-redirective applications. When impacted from the side, a temporary redirective impact attenuator redirects the errant vehicle back toward its original travel path without allowing gating and can be used in both permanent applications as well as in a work zone. Temporary mechanical attenuators are anchored to the ground and the hazard. Temporary mechanical attenuators will require a level concrete of asphalt pad.
