| 摘要： | It took two years of development for Varley and Gulliver to develop its HiMast passive post designed to shear or breakaway following a vehicle impact. The UK company says that the HiMast, which comes in five section sizes, is rated BS.EN.12899-1:2007 and BS.EN.12767:2007. They are made in either aluminium, steel or glass reinforced plastic, passive sign posts have either high-energy, low-energy or non-energy absorbing qualities which reduce the risk of injury to vehicle passengers in the event of a collision. As outlined in the UK's Institute of Highway Engineers' Sign Structures Guide 2021, when a vehicle strikes a structure, such as a standard lighting column at moderate to high speed, it is probable that the car will suffer serious structural damage. During a high-speed impact, despite the use of seat belts and air bags and even if the car remains relatively undamaged, the forces on the internal organs of vehicle occupants can cause serious or fatal injuries. Stacy Willis, solutions manager at Varley and Gulliver, said the company's range of passive posts "are strong enough to support large road signs but are designed to break off safely if a vehicle collides with them, thus reducing the impact for the driver and other passengers". |
