Patent ID: 8714525

Claim:
A manipulator for lifting at least one conductor of an energized electrical line from a pole, comprising: a lifting assembly having a first mobile element movable between a lowered position and a raised position; a first motor unit coupled to the lifting assembly so as to controllably move the first mobile element between the lowered position and the raised position; a fastening assembly for fastening the lifting assembly to the pole so that a displacement of the first mobile element follows a displacement axis parallel to the pole to which the lifting assembly is fastened; a transverse displacement assembly mounted on the first mobile element, the transverse displacement assembly having a second mobile element extending transverse to the first mobile element and movable along a transverse axis with respect to the displacement axis of the first mobile element, the second mobile element being provided with at least one upwardly projecting insulator and at least one conductor holder mounted on the at least one insulator for receiving the at least one conductor of the electrical line to be lifted and movable by the second mobile element along a course extending on opposite sides of the displacement axis of the first mobile element, wherein the second mobile element includes a lower member disposed on the first mobile element an upper member structurally supported by and spaced apart from the lower member, and at least one electrically insulating element extending between the lower member and the upper member and structurally connecting the upper member and the lower member, wherein the at least one upwardly projecting insulator, having the at least one conductor holder mounted thereon, is disposed on the upper member; a second motor unit coupled to the lower member of the second mobile element so as to controllably move the second mobile element along the transverse axis; and a control unit for controlling the first and second motor units.
