20090206305 | Remote manipulator for manipulating live multiple sub-conductors in a single phase bundle - A manipulator for separating sub-conductors in an energized single phase bundle includes a rigid support member and first and second actuators mounted on the support member, wherein each actuator is independently actuable of the other. Insulators are mounted on each actuator. A selectively releasable coupler is mounted on each insulator for selectively releasable coupling of each insulator to a corresponding sub-conductor. The actuators extend corresponding insulators independently of one another from the support member to thereby separate from each other by an optimized separation distance the distal ends of each insulator When the corresponding sub-conductors of the single phase bundle are releasably coupled to the corresponding distal ends of the insulators the surge impedance loading of the single phase bundle may be improved by separation of the corresponding distal ends of the insulators and the sub-conductors by the optimized separation distance. | 08-20-2009 |

An actuated scissor linkage is mounted to the beam and the boom mounting adaptor for selectively adjusting an angular position of the beam relative to the boom mounting adaptor. | 07-12-2012 |
20130015419 | Stringing block for aerial electric conductorAANM Tukachinsky; Arie LeibAACI HaifaAACO ILAAGP Tukachinsky; Arie Leib Haifa IL - A stringing block for aerial electric conductor or other aerial cable, intended for hanging to electric line structures, insulators etc., suitable for both manual and helicopter pilot line or conductor stringing, is disclosed. The block comprises one or more ring-shaped sheaves, each one running over one or two small wheels, installed on a small size frame and rotating around their axes. The block is light enough for to prevent conductor/pilot line escaping the shave groove and friction on the shave flange. | 01-17-2013 |
20130134369 | METHOD AND APPARATUS FOR PROVIDING TEMPORARY SUPPORT AND A MEANS FOR RELOCATING ENERGIZED ELECTRICAL CONDUCTORS - A temporary support and conductor re-locator includes a mounting arm and corresponding mounting bracket on one end of the arm, the other end supporting a pivotally mounted insulator depending downwardly from a crank arm. The upper end of the crank arm is attached to an actuator which, upon actuation, pivots the crank arm and insulator about the end of the support arm so as to rotate up and out of the way an energized conductor contained in the wire holder at the bottom end of the insulator. The support arm is temporarily mounted to an existing transmission line tower or pole so as to extend outwardly substantially horizontally therefrom thereby cantilevering outwardly of the tower the end of the arm supporting the crank arm and insulator. Actuation of the actuator firstly elevates a lower portion of the crank arm then rotates the crank arm about the cantilevered end of the support arm. | 05-30-2013 |
