80 WZThe first temporary and redirective crash cushion
Go to crash cushion
SMA Crash Cushions for work zones offer high preformances and perfectly protect the fixed obstacles in zones where the carriageway presents a road constriction.
The base structure is completely in electro-welded steel, with a 5/6 mm thick plate and a monorail guide for the sliding bars, linked to retaining panels of the crashboxes.
The bumper (frontal panel) is the rigid connection among the sliding side panels which deform after the impact. At the same time, the central panels crash the crashboxes that gradually dissipate the kinetic energy coming from the impact.
