A cable guardrail release system includes a first number of anchor posts installed adjacent a roadway. Each of the first number of anchor posts secures an end of a respective cable. Each anchor post is operable to release the respective cable secured by the anchor post upon a vehicle impact to the anchor post. The system may include a length of need section that includes a plurality of intermediate support posts each configured to support each of the respective cables. The length of need section may include portions of each of the respective cables running in between the plurality of intermediate support posts. Each anchor post may be configured to resist release of the respective cable secured by the anchor post upon a vehicle impact to the length of need section generally at an angle to the flow of traffic on the roadway.
L'invention concerne un système de libération de glissière de sécurité à câbles (10) comprenant un premier ensemble de poteaux d'ancrage (12, 14, 16) installés adjacents a une route. Chacun des premiers poteaux d'ancrage (12, 14, 16) sert à fixer une extrémité d'un câble respectif (12, 24, 26). Lors d'un impact de véhicule sur les poteaux d'ancrage (12, 14, 16), chacun de ces poteaux (12, 14, 16) libère le câble respectif (12, 24, 26) qui est fixé dessus. Le système (10) peut comprendre une longueur de section initiale comportant plusieurs poteaux supports intermédiaires (18, 20), chacun étant configuré afin de supporter chacun des câbles respectifs (22, 24, 26). La longueur de la section initiale peut comprendre des portions de chacun des câbles respectifs (22, 24, 26) passant entre les poteaux supports intermédiaires (18, 20). Chaque poteau d'ancrage (12, 14, 16) peut être conçu afin de résister à la libération du câble respectif (22, 24, 26) fixé au poteau d'ancrage (2, 14, 16) lors de l'impact d'un véhicule sur la section initiale, généralement selon un angle par rapport à l'écoulement du trafic sur la route.
