Towable impact attenuator |
摘要 |
A crash attenuator includes a crash cushion having a front end, a rear end, and a trailer hitch component disposed adjacent the front end. The trailer hitch component is capable of being secured to a mating hitch component located on a towing vehicle, such that the hitch components are capable of being rotated relative to each other about a substantially vertical axis. The crash attenuator further includes at least one wheel supporting the crash cushion. The wheel is rotatable about a substantially horizontal axis and is spaced rearwardly from the hitch component. A pair of tethers are positioned on opposite sides of the hitch component and are moveable relative to one or more retraction mechanisms connected to the crash cushion.
