<p>PURPOSE:To execute stringing efficiently without constructing scaffolds, by mounting the upper side metallic-wheel of vertically connected ones and an automatic running machine on one strip of previously set wire, to bind the lower side metallic-wheel with an auxiliary rope, and by pulling the tip of an interval retaining rope with the automatic running machine. CONSTITUTION:On one strip 1L of previously set wire between iron towers T1 and T2, an automatic running machine 4, and the upper side metallic-wheel 1 of pair metallic-wheels 1, 1' bound vertically with a connecting rope 2 are mounted. With an interval retaining rope 3, the interval of the metallic wheel 1 is properly retained, and at the same time, the automatic running machine 4 is moved from the iron tower T2 to the tower T1, and the metallic wheel 1 is developed and an auxiliary rope l1 is payed out. When a stringing is thick and the weight is heavy, then the rope l2 of great strength is bound to the rope l1 and is connected to a newly set wire 2L. The pair metallic wheels 1, 1' are collected at the iron tower T1 and at the same time, a plurality of non-inversion metallic-wheels 10 are moved on the rope l2, and the newly set wire 2L is pulled and the wheels 10 are led out with a rope P1. As a result, the construction of scaffolds is not needed, and stringings are arranged easily and increasingly.</p> |
