FIELD: transport.

SUBSTANCE: invention relates to devices, blocking vehicle movement, namely to automatic barriers with electric drives with the function of automatic regain of closed position. Automatic barrier contains a body, equipped with a drive with a shaft placed horizontally, base rigidly connected to the drive shaft ratatable in a vertical plane, a turn sensor, a holder with a blocking boom, mounted on the base and rotatable under action of a horizontal load and a closing means. Holder is made in the form of a thick-walled pipe-holder, which is fixed on the rotary axis, installed through the pipe-holder on one side of the base, and is connected to the base by a fixing means on the other side of the base. Closing means is made in the form of at least one shock absorber with a force of 600-1,000 N, hinged by one end on the base to the fixing means, and by the other end - on the pipe-holder at a distance of not more than its diameter from the rotary axis in the direction of the blocking boom.

EFFECT: technical result is a simplified design, reduced regain time of the closed position of the blocking boom and increased operational reliability.
