A ROAD BARRIER AND A METHOD FOR MANUFACTURING THEREOF

摘要

A road barrier comprising a support (101) to which a transverse beam (102) is connected via a spacer (110) such that upon impact the transverse beam (102) moves towards the support (101). The spacer (110) is movable upon impact and coupled, via coupling means (130, 150, 160, 170), with a rotatable energy absorber (140) mounted below the transverse beam (102) and comprising at least one rotor (142, 143) for absorbing in rotational movement at least part of the kinetic energy imparted to the transverse beam (102).
