ABSTRACT:
A trenching device for previously laid cable or pipeline, particularly those laid under water, has a plough (1), means (8) for following the cable or pipeline, a carriage (9), which may be a tractor, connected to the plough through a towing member (6), and vertical pivots between the towing member and the plough and the towing member and the carriage.
The double pivot system allows the plough to follow the cable or pipeline independently of the motion of the carriage.
