<p>PURPOSE:To facilitate drawing of wire by supporting a pull rope and a supporting rope in parallel, while separating horizontally, in the gate frame of an intermediate supporting unit supported on a steel tower then pulling a carrier, which travels on the supporting rope by means of the pull rope. CONSTITUTION:A drawing apparatus 1 comprises an intermediate support 2 and a carrier 3. A set of three intermediate supports 2, arranged in the direction perpendicular to the drawing, is suspended through a base body 31 and a suspending section 15 from a steel tower (not shown in the figure). First and second members 13, 15 for supporting a pull rope J and supporting rope S, respectively, are arranged while being separated horizontally in gate type frames 10-12 on the intermediate support 2. The carrier 3 is pulled by the pull rope J through a connecting arm 53 and a joint 43 and travels on the supporting rope S thus drawing the wire. By such arrangement, contact between the pull rope and the supporting rope is prevented and the wire is drawn smoothly.</p> |
