ANTI-RAM TYPE BARRIER Russian patent published in 2021 - IPC E01F13/12 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical devices, in particular to barrier type means of restricting vehicles movement designed to stop vehicles of all categories in event of unauthorized passage to protected, high-security facilities and territories. The anti-ram type barrier includes a base, supports, a beam with a pre-stretched power cable inside it, an additional power cable made inside the beam with a length of 1.1-1.2 of the length of the power cable and a diameter of 1.2-1.4 of the diameter of the pre-stretched power cable.

EFFECT: increase in barrier anti-ram properties due to additional power cable of greater length and diameter in addition to pre-stretched power cable to ensure uniform distribution of the interaction energy across all the power elements of the anti-ram barrier under dynamic loading.
