A vehicle crash barrier constructed primarily of structural tube members having an energy-absorbing connection between horizontal rail members and vertical post members. Horizontal rail members are provided with one or more deformable flanges adjacent to each end to be connected to a vertical post member. Vertical post members include a channel adjacent a top end for receiving the rail end and flange. The rails are connected to the vertical members by downwardly sliding the flanged end into the vertical channel until the rail rests upon a bottom stop. A reinforcing cap is positioned on the top end of the vertical member to prevent upward movement of the rail and to strengthen the vertical post structure. Shims may be installed between the flange and the channel walls to limit horizontal rail movement.

Structural tube based vehicle crash fence

A vehicle crash barrier gate constructed primarily of structural tube members and having an energy-absorbing connection between horizontal movable gate member and vertical post members. The gate member is provided with one or more deformable flanges adjacent to each end. Each post includes a vertically extending channel for receiving a respective gate member end and the flanges. An inwardly facing, vertically aligned opening in each channel allows the gate member to extend therethrough and span the space between the posts. The vertical extent of the openings spans the required vertical movement of the gate member. One or more reinforcing elements are disposed on the posts proximate to the elevation at which the gate member is positioned to prevent vehicle passage to strengthen the vertical post structure. A drive apparatus is provided to move the gate member vertically between an open position, typically at grade level, and a closed position, typically elevated above grade level.
