    • An impact head for a road guardrail (1) including cable routing means (2) adapted to form a convoluted path through which a cable can be threaded. The convoluted path that the cables (15) must follow through the impact head of the invention restricts movement of the cable (15) through the head, thereby providing sufficient friction to slow down the movement of the impact head during a vehicle impact. Also disclosed is a method of constructing a guardrail including the steps of slidably interconnecting a plurality of rails and attaching them to posts, positioning the impact head as claimed at one end of the slidably interconnected rails, threading at least one cable through the impact head and anchoring the cable to the ground.
    • 本发明涉及护栏和护栏冲击头,其用于需要通过屏障隔离的漫游网络或车辆道路车道。 本发明提供了一种用于护栏的冲击头,包括电缆布线装置,其适于形成电缆可穿过的回旋路径。 电缆必须贯穿本发明的冲击头的旋转路径限制电缆通过头部的移动,由此提供足够的摩擦力以减慢冲击头在车辆撞击期间的运动。 本发明还提供了一种构造护栏的方法,包括以下步骤:将多个轨道滑动地互连并将其附接到柱上,将根据前述权利要求中任一项所述的冲击头定位在所述可滑动连接的轨道的一端,至少穿线 一根电缆通过冲击头并将电缆固定在地面上。
