Abstract
A traffic barrier section with a centrally-located, built-in carrier is disclosed. The carrier includes a fluid-operated ram which is connected to an axle carrying wheels located below the ram. Then the wheels are in a retracted position, the barrier section rests on the ground and when the wheels are extended, the barrier section is supported fully on the wheels. In that position, a plurality of the barrier sections which are pivotally connected in end-to-end relationship can be moved from one construction site to another as needs change. Each axle and the wheels can be turned to a position other than perpendicular to the longitudinal extent of the barrier section so that some of the barrier sections can be moved transversely to place them in other than a straight line position.
Claims14
In combination, a plurality of rigid, non-articulated elongate traffic barrier sections, each of said traffic barrier sections having connecting means at ends thereof for pivotally connecting the barrier sections in end-to-end relationship, each of said traffic barrier sections having a traffic barrier carrier built in at a central portion of the section between the ends of the section to aid in raising the section for transportation from one location to another, each of said carriers comprising wheel means movably carried by the carrier, and moving means connected to said wheel means for moving said wheel means between an upper position in which said barrier section is supported on a surface and a lower position in which the section is raised above the surface.
A traffic barrier carrier for raising a traffic barrier section above the ground for transportation from one location to another, said carrier comprising means forming a compartment, a fluid-operated ram having a downwardly-extending piston rod in said compartment, an axle located below said compartment, wheels on end portions of said axle, a shaft connected to said axle and extending upwardly, rotatable connecting means connecting said shaft and said piston rod to enable said shaft to be turned independently of said piston rod, means for supplying fluid to said fluid-operated ram, and turning means engagable with said shaft for turning said shaft and said axle independently of said piston rod.
In combination, an elongate traffic barrier section and a traffic barrier carrier positioned between ends of said section to aid in raising said section for transportation from one location to another, said carrier comprising wheel means movably carried by said section, moving means supported by said section and connected to said wheel means for moving said wheel means between an upper position in which said barrier section is supported on a surface and a lower position is which said section is raised above the surface, an additional elongate traffic barrier section, said additional section having a tapered end with a recess, and a tow bar pivotally connected to said tapered end and movable into said recess in said tapered end.
