ABSTRACT:
A taphole plugging device has an extension arm which can be swiveled about a fixed axis by a drive train operated by a motor. At its end remote from its pivot, the extension arm carries the plugging gun. The drive train and motor for the extension arm are all carried by the extension arm and act between the point on the extension arm spaced from the pivot of the extension arm, on the one hand, and a fixed support on which the extension arm is swingable, on the other hand.
