摘要

The safety barrier has multiple supporting poles that rise from a base area, and one upper horizontal ledger joins the poles, and one lower horizontal ledger that separates upper horizontal ledger from the poles. The lower ledger is linked to each post through a circular tube damper located inside a folded sheet metal, welded on the one hand to support and on the other united through fixing unit. The circular tube damper is located inside the folded sheet, which is pre-deformed after the impact of a vehicle ledger against the underside of the security barrier.
