BOOM MOUNTABLE ROBOTIC ARM

摘要

A boom mountable robotic arm (20) for temporarily supporting an elongate conductor comprises a rigid member (28) adapted for mounting onto an upper end of a boom (22), an electrically insulated support post (42) mounted to said rigid member, at least two rotation devices for selectively controllable rotation of said rigid member and said at least one electrically insulated support post about corresponding axes of rotation, wherein a first axis of rotation (68) is an axis of rotation extending substantially laterally across said rigid member for rotation of said at least one electrically insulated support post relative to and substantially along said rigid member, and wherein a second axis of rotation extends laterally of and between said rigid member and said upper end of said boom for rotation of said rigid member relative to said boom in a substantially vertical plane so as to level said rigid member.
