Abstract
This device comprises a cable working line bearing a lower assembly and a winch for maneuvering the line.The hydraulic central unit (46) of the winch includes a tank (50) for storing a hydraulic control fluid, a pump (52) for driving the hydraulic fluid, connected to the tank (50) through an upstream conduit (54) and at least one hydraulic motor (56) for driving the drum (42) connected to the pump (52) through an intermediate conduit and connected to the tank (50) through a downstream conduit.The hydraulic central unit comprises a regulator (62) for the hydraulic fluid flow rate at the outlet of the pump (52). The regulator (62) is driven according to at least one hydraulic fluid pressure depending on the load exerted on the motor (56) by the rotary drum (42), said or each pressure being directly taken on one of said conduits.
