Abstract (en)

[origin: EP0837218A2] The energy supply method is used for measuring and/or control devices positioned adjacent the bore head of the horizontal boring machine, by utilising the rotation of the feed screw (2) for driving an electrical generator (11) via a cogwheel mechanism (10). The electrical supply can be maintained when the bore head is at a standstill by using energy storage capacitors or batteries, the electrical supply system contained within a protective sleeve (6) adjacent the bore head.
