FIELD: traffic management.

SUBSTANCE: invention concerns small-sized movable gates in a continuous barrier-type road fence for the organization of emergency passage through the fence or road works on the road or roadsides for temporary or permanent use. Barrier gates contain a fixed part in the form of stationary blocks that are autonomously fixed in the roadway on both sides of the gate, and at least one movable wing connected to the block and made with the possibility of opening/closing the passage in road fences for the passage of vehicles by turning or rolling back. The block and the wing are made in the form of a hollow metal structure made of a wave profile made of galvanized steel with a thickness of at least 2 mm, inside which an energy-absorbing damping device consisting of several rows of a pre-stretched strained steel cable is placed in the wing, and the inner space of the block is applicable for rolling the wing into it, which is rolled back when the passage is opened. To open the gate by turning in one or different directions, the gate contains a reversible jumper, and wheel supports and guide rollers for smooth movement during a rollback opening.

EFFECT: expansion of the range of solutions for traffic management.
