Abstract:
1. An outrigger for carrying at least one elongate electric conductor at a distance outward from a support, the outrigger comprising: a first arm which is elongate and has a proximal end and a distal end, a first support device at the distal end of the first arm, a second support device at the proximal end of the first arm, a second arm which is elongate and extends from the second support device to a distal end of the second arm, and a third support device at the distal end of the second arm, the first and second arms are arranged so that the second support device lies between the first and third support devices, the first support device being adapted for suspending a portion of a first elongate electric conductor from the distal end of the first arm, a major length portion of the first support device is substantially straight and extends substantially perpendicularly from an end of the first arm, a minor length portion of the first said support device extends from a distal end of the major length portion of the first support device and is not aligned with that major length portion, and movement of the outrigger along the first elongate electric conductor can be resisted by engagement of the major and minor length portions of the first support device with the first elongate electric conductor, the third support device is adapted for suspending a portion of a second elongate electric conductor from the distal end of the second arm, the second support device is adapted for suspending the outrigger from a support, the second support device being pivotally connectable to the support at an upper hanger axis and pivotally connected relative to the first arm and the second arm at a lower hanger axis, the outrigger being adapted so that when the outrigger is suspended from the support by the second support device, the portion of the first elongate electric conductor is suspended from the first support device and the portion of the second elongate electric conductor is suspended from the third support device, the outrigger has a rest position in which the first arm extends outwardly from the support, and the second arm extends outwardly from the support, the outrigger being movable from the rest position in a direction toward the support when the first support device or the portion of the first electric conductor is impacted to move the first support device and the portion of the first elongate electric conductor toward the support, and afterwards to move the outrigger back to the rest position, the outrigger being movable by the second support device pivoting relative to the support about the upper hanger axis and/or the first arm pivoting relative to the second support about the lower hanger axis, the outrigger being movable from the rest position in a direction toward the support when the third support device or the portion of the second electric conductor is impacted to move the third support device and the portion of the second elongate electric conductor toward the support, and afterwards to move the outrigger back to the rest position, the outrigger being movable by the second support device pivoting relative to the support about the upper hanger axis and/or the second arm pivoting relative to the second support about the lower hanger axis.
