摘要： An energy absorbing system. The system includes an energy absorber mechanically coupled to a net, a joint mechanically coupled to an anchor, and a support mechanically coupled to the net via a frangible connector. The frangible connector may uncouple the support from the net upon application of at least a threshold force to the frangible connector. The joint may pivot on a horizontal axis and support the energy absorber at a predetermined angle relative to ground level.

摘要： An energy absorbing system. The system includes two anchors, a net mechanically coupled thereto and spanning a roadway, and a first raising/lowering arm arranged on one side of the roadway. The first raising/lowering arm mechanically coupled to and supporting an upper portion of the net via a first upper frangible tensioner and mechanically coupled to and supporting a lower portion of the net via a first lower frangible tensioner. A second raising/lowering arm arranged on another side of the roadway, the second raising/lowering arm mechanically coupled to and supporting an upper portion of the net via a second upper frangible tensioner and mechanically coupled to and supporting a lower portion of the net via a second lower frangible tensioner. The first and second upper and first and second lower frangible tensioners decouple from the net upon application of a predetermined force.

摘要： A heavy duty ground retractable automobile barrier for a railroad crossing. Concrete bunkers are placed at each side of a roadway. An upstanding concrete-filled steel pipe fixed in each bunker has a sleeve for rotational and axial movement. Shock absorbers are mounted on each sleeve. A net extends across the road and is attached to the opposite ends of the shock absorbers. Collision of an automobile with the net creates tensile forces in the net. The shock absorbers expand while rotating about the pipe's axis in response to tensile forces from the net that meet or exceed a minimum threshold. Forces from the net pass through the axis of the steel pipe. The net is stored in a pit transverse the roadway parallel to the railroad tracks and is raised and lowered as appropriate. The net includes a cable that extends across the road in a wave pattern, having peaks, valleys and midpoints, wherein tangents of the wave midpoints are at least 90 degrees from tangents of the peaks and valleys.
