摘要

IN A PROCESS FOR PLACEMENT OF CONSTANT MEASUREMENT OF AT LEAST THREE PATHS (2, 3, 4) PLACED CLOSE TO ONE ANOTHER, they passed A PAIR OF crosspieces (9, 10), UNDER THE PATHS outermost (2, 4), AND UNDER EACH OF THE rAILS (3.1 or 3.2) CENTRAL (3) TRAJECTORY CONTACT THE ULTIMA, the space between the rails (3.1, 3.2), where they are attached in such a way that the joints ( 11) PEER CONSECUTIVE CROSSBAR (9.K, 10.KY 9.K + 1, 10.k + 1) are located between the paths (3.1 and 3.2) Alternate Side an axis (12) perpendicular to the axes SILLS, AND HEADS OF AT LEAST THREE CONSECUTIVE LONG BARS (9.K, 10.k + 1, 9.K + 2) passing under the axle (12) are rigidly interconnected by connecting means (13) .
