An erectable barrier unit as well as a barricade made of a plurality of units are disclosed. The erectable barrier unit comprises a base and at least one movable hurdle connected to the base wherein the movable hurdle can instantly erect from a resting position in which the hurdle is adjacent to the base to an erected position in which a predetermined angle is formed between the hurdle and the base.

A traffic control device, for use with a roadway receiving vehicles travelling longitudinally along the roadway, includes a housing mounted transversely across the roadway with an upper supporting surface that supports the vehicles rolling over the housing. A frame comprised of a shaft supporting tire puncturing members thereon is rotatable within the housing between stored and working positions of the tire puncturing members relative to the upper supporting surface of the housing. Offset counterweights are coupled to the frame to bias the tire puncture members towards the working position. An upper stop member on the housing, formed of resilient material, is engaged by the frame in the working position and is adjustable in height to control position of the tire puncturing members in the working position.

A vehicle barrier apparatus includes a base and a deployable element. The deployable element is rotatably coupled to the base, enabling transition from a stored orientation to a deployed orientation. The deployable element can engage a vehicle physically in the deployed orientation to impair vehicle motion. An actuating mechanism is mechanically coupled to the deployable element cause the deployable element to move from the stored orientation to the deployed orientation responsive to a trigger. The apparatus may include a triggering device that detects the vehicle and provides the trigger to the actuating mechanism responsive to the detection. In addition, or alternatively, the apparatus can include a communications interface that receives a trigger communication from a remote location and causes the trigger to be provided to the actuating mechanism. The apparatus may be portable.

A weight-limiting roadblock device according to the present invention includes a body, wherein the body is provided with a weight detection device, the weight detection device includes a push rod, and the left side of the weight detection device is also provided with an overweight warning device. The overweight warning device includes a railing. The present invention is provided with a putter to detect moving vehicles to avoid the loss of electrical energy caused by the use of sensors. The device also has a roadblock to intercept vehicles that forcibly break through the railings and prevent illegal vehicles from forcibly passing through. The left side of the roadblock is also equipped with an elastic baffle to protect the vehicle being intercepted to prevent safety accidents such as rollover due to interception. This device has accurate measurement, obvious interception effect, and no hidden dangers. It is suitable for many Kind of traffic intersection.

A traffic control device, for a roadway receiving vehicles travelling longitudinally along the roadway, includes a housing, which may be formed in two or more modular sections, mounted transversely across the roadway. A frame comprised of a shaft supporting tire puncturing members thereon is rotatable within the housing between stored and working positions for selectively puncturing tires. In modular embodiments, the shaft of each module includes a joiner plate supported at one end of the shaft to enable rigid connection between the shafts of adjacent modules. In some embodiments, offset counterweights are coupled to the frame to bias the tire puncture members towards the working position, and an upper stop member on the housing, formed of resilient material, is engaged by the frame in the working position and is adjustable in height to control position of the tire puncturing members in the working position.

Ground-based barrier systems for permitting or inhibiting vehicle passage, and capturing unauthorized vehicles. One example of the present technology is directed to a ground-based vehicle barrier system, comprising a bollard movable between a recessed position permitting vehicle passage and an extended position inhibiting vehicle passage. A link is connected to or formed as part of the bollard. The link is extending transverse to the bollard. The ground-based vehicle barrier system further comprises a drive connected to a connection point of the link and configured to selectively move the bollard in the recessed and extended positions.

Barriers, such as vehicle impact barriers for placing upon an existing surface such as a road surface, or a paved surface, or a pedestrian surface. Surface-mountable and removable barriers are described for use as vehicle impact barriers. Such barriers may be employed for rapid deployment in a street, causeway or other route.
