1. A boom mountable robotic arm for temporarily supporting one or more energized electrical conductors comprising:
a single elongate unitary beam adapted for coupling with an upper end of a boom, a boom adaptor mountable to said upper end of the boom, at least one electrically insulated support post coupled to said beam, each post of said at least one electrically insulated support post adapted for temporarily supporting an energized electrical conductor, at least two rotation couplings for selectively controllable rotation of said beam and said at least one electrically insulated support post about at least two corresponding axes of rotation, wherein a first axis of rotation of a first corresponding rotation coupling of said at least two rotation couplings is chosen from the group comprising: a) at least one axis of rotation extending substantially along a longitudinal axis of said beam, for rotation of said at least one electrically insulated support post relative to and substantially laterally of said beam, b) at least one axis of rotation extending substantially laterally across said beam at base ends of said at least one electrically insulated support post for rotation of said at least one electrically insulated support post relative to and substantially along said beam, whereby said at least one electrically insulated support post is selectively adjustable between a retracted position substantially laid flush along said beam and a pick-up position ready to receive a conductor being supported, and wherein a second axis of rotation of a second corresponding rotation coupling of said at least two rotation couplings extends laterally of and between said beam and the upper end of said boom for rotation of said beam relative to said boom in a substantially vertical plane; and wherein said beam is an elongate upper beam assembly rotatably mounted to said boom adaptor for rotation of said upper beam assembly about said second axis of rotation relative to said boom, and wherein said second corresponding rotation coupling includes a selectively actuable first actuator mounted between said upper beam assembly and said boom adaptor for selectively adjusting an angular position of said upper beam assembly relative to said boom adaptor, and wherein said selectively actuable first actuator is mounted so as to cooperate between said beam and a scissor linkage mounted to said beam and said boom adaptor for selectively adjusting an angular position of said beam relative to said boom adaptor wherein said scissor linkage includes first and second linear members, each said first and second linear members having, respectively, opposite first and second ends, said first ends of said first and second linear members pivotally connected to one another, said second ends of said first and second linear members pivotally mounted to, respectively, said beam and said boom adaptor, said first actuator pivotally mounted at a first end thereof to said first ends of said first and second linear members, and a second end of said first actuator, opposite said first end of said first actuator, mounted to said beam. |
