Abstract: An elevated walkway support system comprising a plurality of horizontal support members supporting said walkway above a foundation, the horizontal support members adapted for attachment at first ends thereof to one or more associated supports; and a plurality of adjustable length braces extending between second ends of respective ones of the horizontal support members and the foundation at a location closer to the first ends than the second ends in a horizontal direction.

Abstract: The tool includes a base having an adjustment wedge, a counter wedge slidable on the inclined surface of the adjustment wedge, a plurality of roller bars in a recess on the upper surface of the counter wedge and a cover member supported by the roller bars. A power screw is used to horizontally displace the adjustment wedge to elevate the counter wedge, cover member and, hence, the load. The plurality of roller bars are confined within a recess to constrain relative movement of the cover member and the counter wedge. To release the cover member for movement, roller bars of reduced diameter at the opposite ends of the wedge are removed to permit the cover member to move relative to the counter wedge. Horizontal adjustment screws cooperate between the cover member and the base to precisely control the movement.
