ABSTRACT:
A cantilevered sliding gate made up of a number of panels is disclosed. The panels are joined by post-tensioning rods, carried within horizontal members of the gate and extending substantially the length of horizontal members of the gate. During gate assembly, a tensile stress is induced in the post-tensioning means, which stress is transmitted to the horizontal member as a compressive stress. The resulting stress pattern results in a stiffening effect on the gate assembly, permitting lighter-weight construction than previously possible. The gate is mounted on vertical supports for movement in a plane defined by the supports.
