To prevent the motorway traffic passing the scene of an accident from slowing down, a masking curtain is erected temporarily on the central safety barrier of the rail or low wall type. This portable curtain consists of PVC tarpaulins (1) provided with eyelets (2) for installing them on aluminium profiled sections (4) fitted with rubber fasteners (3). The profiled poles (4) are slid into the U-shaped profiled sections which support the rails or attached by means of aluminium stirrups (6) which fit over the top of a central barrier (8), to which they are secured by wing bolts (7). |
