Abstract

L'invention concerne un mécanisme de treuil destiné à être monté sur un navire ou analogue Ce mécanisme comporte deux pompes-moteurs hydrauliques à déplacement constant 1, 2 qui entraînent un mécanisme 3, 4 de traction de câble et qui sont alimentées par du fluide à haute pression provenant d'une pompe 18 et d'un accumulateur à haute pression 17. Deux clapets de non-retour 20, 23 permettent à la pompe-moteur 2 de ne pas être reliée à l'accumulateur et de fonctionner en pompe. L'invention s'applique notamment au levage d'objets à partir de la surface de la mer.
