ABSTRACT:
Laying apparatus and method for cables, lines, conductors or suchlike. The apparatus comprises at least a hydraulic circuit provided with a variable delivery feed pump and with a motor connected to the feed pump in order to drive laying members for the cables and suchlike. The hydraulic circuit comprises detectors able to detect the value of pressure of the oil inside the hydraulic circuit and to compare it with a pre-determined pressure value, and valves connected to the detectors and able to reduce the delivery of the feed pump in the event that the pressure measured exceeds the pre-determined pressure value.
