An enhanced vehicle barrier system. The enhanced vehicle barrier system including bases located on opposite sides of an area through which a vehicle may pass, first and second arms hingably mechanically coupled to a base, first, second and third members, a raising/lowering mechanism, and a cable in mechanical communication with at least one of the first, second, and third members, the cable having connecting points located on opposite sides of the area through which a vehicle may pass, and wherein, in one position, at least portions of the first, second, and third members and the cable may be high enough to encounter a front of a vehicle.
E01F 15/00 - Dispositions de sécurité pour ralentir, maintenir sur la route ou arrêter les véhicules à la dérive, p.ex. bornes de protection ou pieux garde-fous; Dispositions pour réduire les dommages occasionnés aux structures du bord de la route par l'impact de véhicules
A removable barricade system having a first sleeve to be affixed to a first bollard, a second sleeve to be affixed to a second bollard, and a barricade attached to the first and second sleeves, the barricade blocks the area between the first and second bollards.
An energy absorbing system. The energy absorbing system includes a supporting member, a barrier pivotable between a first angular position and a second angular position, where the barrier becomes mechanically coupled to the supporting member when arranged at a predetermined angular position, and an energy absorber mechanically coupled to the supporting member, where the energy absorber absorbs energy when the supporting member travels from a first position to a second position.
An energy absorbing system includes a supporting member (4), a barrier (2) mechanically connected to the supporting member. The barrier being pivotable between a horizontal position and a predetermined angle. An energy absorber (8) mechanically coupled to the supporting member such that impact energy is absorbed when the barrier is impacted by a vehicle (20), thereby causing the supporting member to travel from a first position to a second position.

An energy absorbing, vehicle capturing system spanning the width of a roadway, includes a net (500) for capturing the vehicle (30), and a mat (2000) uniquely shaped to accommodate the net (500), when the net is not deployed and is laying against the roadway surface, thus protecting the net from abrasion by vehicle tires running over the net, when the net is not in a deployed position.
An energy absorbing system. The system includes an anchor (300), a net (500) mechanically coupled to the anchor (300), and a support (400) mechanically coupled to the net (500) via a frangible connector (450), wherein the frangible connector (450) uncouples the support (400) from the net (500) upon application of at least a threshold force to the frangible connector (450). In another aspect, the system further includes an energy absorber (800) mechanically coupling the net (500) and the anchor (300). In another aspect, the system further includes a joint (700) mechanically coupling the energy absorber (800) and the anchor (300), wherein the joint (700) pivots on a horizontal axis.
A heavy duty ground retractable automobile barrier for a railroad crossing (12). Concrete bunkers (30) are placed at each side of a roadway (10). An upstanding concrete-fill steel pipe (32) fixed in each bunker (30) has a sleeve (72) for rotational and axial movement. Shock absorbers (84) are mounted on each sleeve (72). A net (20) extends across the road (10) and is attached to the opposite ends of the shock asorbers (84). Collision of an automobile (26) with the net (20) creates tensile forces in the net (20). The shock absorbers (84) expand while rotating about the pipe's axis in response to tensile forces from the net (20) that meet or exceed a minimum threshold. Forces from the net (20) pass through the axis of the steel pipe. The net (20) is stored in a pit (38) transverse the roadway (10) parallel to the railroad tracks (12) and is raised and lowered as appropriate. The net (20) includes a cable tha textends across the road in a a wave pattern, having peaks, valleys and midpoints.
