The hydraulic transmission systems ensure the reliability and long life of the Hydrascrew, whilst transmitting high low-speed torques, thanks mainly to a start-up booster system.

morillon principle hydrascrew
Smooth running and good flexibility for optimal security. Hydraulic limitation of the torque for planetary feed, safeguarding the extraction screw and its transmission.
Speed regulation without loss of efficiency, at constant torque, with no speed variator and no overheating. Possibility of turning in both planetary directions.
