Abstract
A self-loading plough assembly comprises a plough (2) having a channel (16) for the passage of a cable or pipe (8) and a cutter or cutters (5) for cutting and lifting a wedge of material from a substrate to form a trench into which the cable or pipe (8) is laid. The assembly also comprises a jib (11) for supporting the plough (2) and a carrier (7) for supporting the jib (11). The plough (2) is rotatably mounted under the jib (11) and the jib (11) is slideably mounted on the carrier (7) in such manner that the jib (11) can be raised or lowered and the plough (2) can be rotated about a horizontal axis to scoop the cable or pipe (8) into the channel (16). The assembly can pick up cable or pipe from the ground, e.g., the sea bed, and load it into the plough without manual intervention for burial, and reverse the procedure if need be.
