Abstract: 1,093,619. Winches; fairleads. C.R.F. OFFICINE MECCANICHE DI PRECISIONE S.p.A. Nov. 19, 1964 [Nov. 19, 1963], No. 47194/64. Heading B8B. [Also in Division H2] In a method of erecting a pair of conductors under tension with a single drive motor, a pair of tensioning cables is used with means for equalizing the tension between the cables. For use with a pair of conductors 1, 2 in a bundle (Fig. 2) the ends of the conductors are joined to a loop 5 the ends of which form the pair of tensioning cables. This loop passes over an equalizing pulley 6 fitted with a counterweight 11 and attached to a drive cable 7. The conductors 1, 2 unwind from supply drums and pass through a braking drum assembly (Fig. 1, not shown). The cable 7 passes over a wheel 32 (Fig. 9) on a guide pulley 29 which hangs from a bracket 26 attached to a pylon arm. The guide pulley 29 has spaced wheels 30 which receive the conductors 1, 2 as the pulley 6 passes between the wheel 32 and a movable anti-running device 25, the tensioning cable being meanwhile maintained central by a further pulley 37. For use with two separate conductors, two separate tensioning cables are used, these being attached respectively to two pairs of drums which are driven through a differential mechanism (Fig. 4, not shown). The drums 12, 13 (Fig. 3) are each divided into two sections 12, 121 and 13, 13<SP>1</SP>, one section of each being solid with its respective shaft. The section fixed to one shaft is connected to the free section of the other drum by pinions 17, 18. The differential equalizes the driving torques on the shafts of the drums. When using a single cable 7 the drum sections are covered with shells of cylindrical sectors (23, 24 in Fig. 5, not shown) and the pinions 17, 18 are removed so that the two drums constitute two rigid systems connected only via the differential which now equalizes the torques applied to the sectors (23, 24). For use with two pairs of conductors in two bundles, the arrangement of Fig. 2 is duplicated, the two drive cables 7 being driven from drums as in Fig. 3.
