TRAFFIC-CONTROL ANTI-RAM BARRIER Russian patent published in 2019 - IPC E01F13/10 

FIELD: transportation.

SUBSTANCE: invention relates to mechanical devices, in particular to means of restricting the movement of vehicles, intended to stop vehicles of all categories in the event of unauthorized travel to protected, sensitive objects and territories. Traffic-control anti-ram barrier comprises base, power supports, beam made of steel section of closed section with wall thickness of 2–25 % of diameter described around circumference profile, in which pre-tensioned power cable is mounted, and hinge support, which provides for beam turn.

EFFECT: increase in barrier's anti-ram properties by optimizing beam structure, which provides increased level of vehicle deformation at initial time point and further destruction of vehicle due to uniform distribution of total interaction energy over all power elements of the barrier.
