Abstract

PROBLEM TO BE SOLVED: To easily produce a cross guide line with no increase of its construction cost by placing two conductors of the guide line with a prescribed distance secured between them in the lengthwise direction and with the relative positions of the conductors reversed to each other and holding the conductors and a tension member between two fixing tapes in a single body. SOLUTION: A cross guide line 1 consists of a tension member 2 and two conductors 3 which are held between two fixing tapes 4 in a single body. The member 2 secures the tensile strength of the line 1, and the coating is applied on the main body of the member 2. The tapes 4 function to unify the member 2 and the conductors 3 in a single body by holding and fixing them. The conductors 3 are placed in the lengthwise direction at both sides of the member 2 and cross to each other at every prescribed lengthwise distance (5 to 100m) with their relative positions reversed to each other. Both conductors 3 are kept in parallel to each other at the parts excluding their cross positions.
