Title
(EN) MULTIPURPOSE ENERGY ABSORBING BARRIER SYSTEM
(FR) SYSTEME DE BARRIERE POLYVALENTE A AMORTISSEMENT
Abstract
(EN)
A restraining barrier (30) is positionable across a roadway in a deployed position to define a restraining zone and may be moved vertically to a passive position by first and second transport components (13, 14). Opposite ends of the barrier are coupled to the first and second transport components (13, 14), respectively, and also couple the barrier to first and second energy absorbers (37, 38) of differing restraintive force in order to stop vehicles (40) of varying weight. A support cable (49) is coupled to an indicator (89) for providing a signal indicating vehicle impact. Additionally, a series of restraining barriers and energy absorbers may provide a series of sequentially differing restraintive forces to stop lightweight and heavier vehicles. The barrier may be a net and include a lower wire below the net assuring effective trapping of autos and trucks of a variety of heights.

Une barrière de retenue (30) peut être placée en travers d'une route en position déployée pour définir une zone de retenue, et être déplacée verticalement vers une position passive par un premier et un second élément de transport (13, 14). Les extrémités opposées de la barrière sont accouplées, respectivement, au premier et au second élément de transport (13, 14), et accouplent également la barrière à un premier et un second dispositif amortisseur (37, 38) ayant une force de retenue différente afin d'arrêter des véhicules (40) de poids différents. Un câble support (49) est couplé à un indicateur (89) qui émet un signal indiquant l'impact d'un véhicule. En outre, une série de barrières de retenue et de dispositifs amortisseurs peuvent fournir des forces de retenue progressives, de façon à arrêter des véhicules légers et plus lourds. La barrière peut être un filet et comporter, sous celui-ci, un fil métallique inférieur assurant un blocage efficace des voitures et des camions de diverses hauteurs.
