Patent ID: 7856862

Claim:
A tool to generate opposite and co-directional forces of high intensity, comprising: a box with a front face and a rear face, suitable for bearing strong pulling or pushing loads between said faces; a linear actuator having a fixed element integral to said box and at least one movable element capable of being guided in said fixed element in order to withdraw or extend telescopically with respect to said fixed element, said movable element protruding from said fixed element at said front face; an electric motor capable of providing a rotational movement; means for transmitting the movement of said electric motor to said movable element suitable for transforming the rotational movement of said electric motor into a translational movement of said movable element; an impact device integrated in said means for transmission, suitable for providing a plurality of impact actions to said movable element for overcoming blocked situations; wherein said box acts as force bearing element between said front face and said rear face, forces being applied through said movable element and said rear face; and wherein said means for transforming the rotational movement of said electric motor into a translational movement comprises a screw mechanism, comprising a screw that is integral with the motor shaft and a nut screw that is integral with said movable element.
