ABSTRACT:
An elongated boom including relatively telescoped base and extension sections is provided with the base section pivotally supported from a mount for oscillation relative thereto about a horizontal axis extending transversely of the base section. First motor structure is provided for adjustably extending and retracting the extension section relative to the base section and a second motor structure is operatively connected between the base section and the mount for angularly positioning the base section relative to the mount. A generally horizontal elongated support arm has one end pivotally supported from the extension section free end for oscillation relative thereto about a horizontal axis extending transversely of the arm and extension section and third motor structure is operatively connected between the extension section and the support arm for angularly shifting the latter relative to the former. An elongated follower is mounted on the support arm for adjustable shifting therealong and fourth motor structure is provided for shifting the follower relative to the arm. One end of the follower includes a first elongated depending fixed jaw and the second follower end includes a second elongated depending pivoted jaw. Fifth motor structure is connected between the follower and the second jaw to angularly displace the latter relative to the former.
