Texas gate
摘要:
The Texas gate includes a base frame adapted to be set into a roadway and a deck assembly secured to said base frame. The deck assembly includes a series of spaced parallel elongated deck members arranged in groups. First and second groups of said deck members are fixed to said base frame in spaced apart flanking relation to a central region of the gate assembly. At least one further group of deck members is pivotally mounted for movement from a lowered position overlying said central region and supported on said base frame in co-planar relation to said first and second groups of deck members to a raised position providing access to an area beneath said central region of the gate assembly to facilitate removal of debris and/or to provide a barrier to road traffic. In a further aspect of the invention there are two said further groups of deck members, each said further group being pivotally mounted for rotation in opposing directions away from one another relative to said first and second groups between said raised and lowered positions.
