20090195083 | Live conductor stringing and splicing method and apparatus - A method and apparatus for handling and/or stringing energized conductor for a high voltage power line conductor for a high voltage power line is provided. The method includes bringing components and workers to the same electrical potential and transferring power from one contractor to another. Associated apparatus is also described. | 08-06-2009 |
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 |
20120175575 | Boom mountable robotic arm - A boom mountable robotic arm for includes a beam pivotally mounted on a boom mounting adaptor, at least two electrically insulated support posts mounted to and spaced apart along the beam, and at least a first rotation coupling and a plurality of second rotation couplings. The first rotation coupling provides pivotal mounting of the beam on the boom mounting adaptor so as to provide selectively controllable rotation of the beam in a substantially vertical plane. The second rotation couplings provide selectively controllable rotation of the electrically insulated support posts about corresponding second axes of rotation between a retracted position substantially laid flush along the beam and a pick-up position ready to receive a conductor being supported. 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 |
20120286108 | BOOM MOUNTABLE ROBOTIC ARM - A boom mountable robotic arm for temporarily supporting an elongate conductor includes a rigid member such as a beam or beam assembly adapted for mounting onto the upper end of a boom for example using a boom adaptor, at least one electrically insulated support post mounted to the rigid member, where each post temporarily supports an elongate electrical conductor, and at least two rotation devices for selectively controllable rotation of the rigid member and the electrically insulated support posts about at least two corresponding axes of rotation. | 11-15-2012 |
20140069717 | BOOM MOUNTABLE ROBOTIC ARM - A boom mountable robotic arm for temporarily supporting an elongate conductor includes a rigid member such as a beam or beam assembly adapted for mounting onto the upper end of a boom for example using a boom adaptor, at least one electrically insulated support post mounted to the rigid member, where each post temporarily supports an elongate electrical conductor, and at least two rotation devices for selectively controllable rotation of the rigid member and the electrically insulated support posts about at least two corresponding axes of rotation. | 03-13-2014 |
