Abstract: A mobile vehicular apparatus for moving an operator around a three-dimensional aerial work location includes a mobile vehicle having a vehicle body, a boom upwardly extensibly and downwardly collapsibly mounted on the vehicle body, a platform mounted on a distal end of the boom, and a manipulator mounted on the distal end of the boom in electrically insulated relation to the platform. The platform and the manipulator are electrically insulated from each other, and hydraulically operated generators are disposed respectively on the platform and the manipulator for energizing respectively electric systems mounted thereon. The electric systems on the platform and the manipulator are interconnected by an optical fiber cable.

Abstract: A mobile vehicular apparatus for moving an operator around a three-dimensional aerial work location such as an electric cable or wire supported on posts includes a mobile vehicle having a vehicle body, a boom upwardly extensibly and downwardly collapsibly mounted on the vehicle body, an operator's cabin mounted on a distal end of the boom, cabin having a vertical recess defined in a rear side thereof, at least one manipulator operatively connected to a front side of the cabin, and a lifter operatively connected to the rear side of the cabin. The lifter is collapsibly storable in the recess and extensible from the recess with a distal end portion of the lifter being positioned in overhanging relation to the cabin, the lifter supporting a winding device on the distal end portion.

Abstract: An electric power supply device on a mobile vehicular apparatus includes an AC generator, a rectifier connected to the AC generator, for rectifying an electric current generated by the AC generator, a regulator connected to the rectifier, for maintaining the voltage with respect to the rectified electric current at a constant level, the regulator being connected to a power line for transmitting the electric current at the constant-level voltage to a DC electric actuator on a master control arm, and a battery connected to the power line. The master control arm controls a slave manipulator arm for processing or handling a workpiece. When the DC electric actuator is subjected to a large load and needs a large amount of electric power, the battery discharges and supplies the stored electric energy to the DC electric actuator.
