摘要： 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.

摘要： 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 tire puncturing 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. A latch bolt threaded into a threaded aperture in the housing selectively retains the tire puncturing frame in the stored position.
