ANTIRAM BARRIER Russian patent published in 2019 - IPC E01F13/06 

FIELD: transportation.

SUBSTANCE: invention relates to means of restricting the movement of vehicles, designed to block unauthorized passage of vehicles through them. Barrier anti-barrier barrier type includes a hinge and two power supports, the beam with the possibility of its rotation in a horizontal plane at an angle of at least 90°. At the ends of the beam, power elements are mounted that extend beyond its envelope. Inside the beam between the power elements a cable of high-molecular-weight polymer fibers is stretched, and the cable thickness is from 0.05 to 0.5 of the beam diameter. On the power supports of the barrier, special hooks are made in such a way that, in case of a ram impact on the barrier, it makes sure that it comes in contact with the power elements of the beam, transferring the load from the cable to the supports.

EFFECT: technical result is to facilitate the construction of the barrier beam and increase the barrier characteristics of the barrier while reducing the material intensity, uniform distribution of the entire interaction energy over all the power elements of the barrier.
