Abstract

The present invention provides a pulling system essentially consisting of two sets of feet () and a hydraulic cylinder (). Each set is positioned on one of the sides of the hydraulic cylinder (). The two sets of feet () have a self-locking mechanism. The self-locking mechanism allows each set of feet to act preferentially on one side and exert powerful forces. The invention further provides a flexible reservoir () capable of equalizing the pressures inside and outside the medium, allowing the operation of a hydraulic system in an environment that is subjected to any pressure value, provided that it is within the operating range of the components. In addition, the maintenance of a closed circuit ensures that no fluid contamination occurs.
