A robot vehicle for hot-line job for transmission and distribution lines which comprises an insulating boom formed of an insulating material at a tip end stage of multiple stage booms, a base end of which is supported on an elevated work vehicle to be capable of swinging, pivoting up and down, and extending and contracting, and a frame provided on the tip end of the insulating boom, the frame mounting thereon double arm manipulators of multishaft construction for performing a distribution work, a slide device for sliding independently these right and left double arm manipulators front to rear, and lifting arms of multishaft construction having a function of lifting a heavy article, so as to allow an operator to perform remote control. An electric actuator is used for driving the double arm manipulators and the slide device, and hydraulic manipulators for driving the lifting arms. Accordingly, a robot vehicle for hot-line job is provided to mount thereon a third arm which enables highly accurate positioning of the manipulators, remote control by an operator and automatic operation through a teaching-playback, has a function of lifting a heavy article, and is small-sized and lightweight.

Robot vehicle for hot-line job

An audio signal amplifier device is disclosed, and includes two parallel compass controller circuits (6, 7), each of the circuits (6, 7) having the identical configuration and including a low compass controlling circuit (1, 8) having a plurality of transformers T.sub.1, T.sub.2 connected in series, a medium compass controlling circuit (2, 9) having a capacitor C.sub.2 and a resistor R.sub.3 connected in series, and a high compass controlling circuit (3, 10) having a capacitor C.sub.3 and an amplifier A.sub.2 connected in series, those three compass controlling circuits being coupled in parallel. The parallel compass controller circuits (6, 7) are connected in series through a pre-amplifier PA.sub.1, wherein the post-stage circuit (7) is coupled with an output transformer T.sub.4 through a pre-amplifier PA.sub.3, and the pre-stage circuit (6) is coupled with an input transformer T.sub.3 through a pre-amplifier PA.sub.2.
