<p>The crash barrier has guide sleepers (3), with U-shaped rails (10), open at the top, for reinforcement. The rails extend from areas below the slightly inclined approach bars (5) to approx. half the height (H) of the guide sleepers. The end faces of the vertical rail flanks are fitted to the inner shape of the bars, to the flat side faces (7) of the sleepers, and to transitional sections, and are welded to these. The base of each rail has a long bore. An anchor passes through the bore, and the rail may be pivoted relative to it. The guide bars (4) are formed as trapezoidal hoods, open at the bottom.</p> |
