Cable and warning tape laying plough - produces downwards sloping slot in side wall of cable trench for tape

摘要

The cable-laying plough lays both cable and the tape that warns of the presence of a cable at the same time - ie in the same work process. The tape warns of the presence of a cable beneath it during later earth works. The cable (4) is laid behind the cutting blade through a chute (3). The warning tape (8) is laid into a slot (5) cut into the side of the trench some way above the cable and sloping downwards to prevent the tape falling out. Since the tape is guaranteed to remain in the slot the cutting of a second precautionary slot is unnecessary.
