<p>PURPOSE:To permit remote live-line work to be performed in an insulated conduction by driving a point end driving gear in a manipulator point end through a pressure hose from a pressure control circuit. CONSTITUTION:A bucket part 3 is mounted to a point end 2a of a telescopic boom 2 in an altitude work vehicle 1, and a live-line manipulator 4 is provided in this bucket part 3. The manipulator 4 mounts to its point end part 4a a live-line work tool 6 throught a point end driving gear 5. The bucket part 3 provides a hydraulic control circuit 8 to be connected to oil hydraulic motors 5a, 5b, provided in the point end driving gear 5, through a pressure oil hose 13. The live-line work tool 6 is driven through the oil hydraulic motors 5a, 5b. Only providing the pressure oil hose 13 to be arranged in the live-line manipulator 4, insulation is perfectly attained because no electric wire is arranged.</p> |
