<p>PURPOSE:To prevent entanglement of rope by composing the traction rope for a loop traction type cable laying system of organic fibers, fitting a guide tongue idly to a universal hook at a joint and arranging a split slip device below the rope supporting face through a predetermined gap thereby exerting frictional thrust onto the rope. CONSTITUTION:An endless rope A for tracting a cable K is composed of organic fibers and guided by means of rollers Rl-R3. A movable table R31 including a plurality of rollers R3 is pulled by means of a spring S thus stretching the rope A. A universal joint U arranged at a joint X of the rope A is provided with a guide tongue U1 and tracts the cable K on a tray T through a universal hook H and a grip G. The roller R1 comprises a pair of split rollers opposing each other and a gap for passing the guide tongue U1 is provided below. Furthermore, required number of caterpillar type friction thruster F are provided and thrust is exerted onto the rope A by means of a drive caterpillar C1 and a driven caterpillar C2. According to the invention, the cable A is prevented from entangling and laid efficiently.</p> |
