ABSTRACT:
The guideway is comprised of upper horizontal stringers (20, 22), lower horizontal stringers (24, 26) vertically oriented diagonal members (30, 32) affixed to the upper and lower horizontal stringers (20, 22 and 24, 26) and horizontally oriented diagonal members (34) are affixed between the lower horizontal stringers (24, 26). These features present a guideway having an upwardly extending U-shape construction which can be supplied with wheel supporting channels (28), upper support channels (35) and the entire structure can be reinforced by ribs (60) and enclosed by a cover (50). The ribs include spaced inner and outer members with joined free ends. A method of installation includes (1) installing the post means; (2) positioning the guideway sections over the post means; (3) lowering the guideway sections; (4) clamping the sections to the post means at four points; (5) repeating steps 2-4 for the adjacent post means and (6) affixing the sections in end-to-end relationship to form a continuous elevated guideway.
