PURPOSE:To make it possible to adjust finely position of a manipulator for broadly reducing burden for positioning the manipulator by providing a slide table moving upward and downward according to feed on thread construction while supporting a supporting member for the manipulator. CONSTITUTION:Manipulators 3 are positioned to rough position on which the manipulators 3 work, through extension of a boom 2. Next, on driving a drive unit 16, the drive is transmitted to ball screws 12a, 12b via sprockets 18a, 18b, chains 19a, 19b and sprockets 15a, 15b. Ball screws 12a, 12b are made to rotate thereby, the slide table 20 is made to move upward and downward and the manipulators 3 supported to this table 20 are positioned selectively to plural numbers of working places with which are dotted upper and lower sides at postures as they stand. As the result thereof, high altitude working such as wiring on high voltage overhead wire can be performed efficiently by the manipulators 3 at the same posture. |
