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. Since the platform and the manipulator are structurally electrically insulated from each other and their electric systems are electrically insulated from each other, the operator on the platform is protected for safety against electric shocks while electric cables or the like are being processed by the manipulator under the control of the operator.
