An important part of upgrades and rehabilitation of tunnels is to protect side area that represent a risk for collisions. The new SMA crash cushions from Automation Manufacturing Services ltd. prove that it is possible to produce space-saving solutions that are easy to install, reliable over time, maintenance friendly and provide a high degree of safety.

The installation can be anchored directly on road surface with no need for extra anchors, that make the safety measure easy to install. In case of collision, most of the structure of the cushion can be reused and there is only need for a limited supply of spare parts.

The base structure is completely in electro-welded steel, made of 5/6 mm thick plate and monorail guide for the sliding bars linked to retaining panels of the absorbing cells.

The additional panels help the redirecting of the vehicle, by absorbing the energy of the lateral impact.
