Assuming that the advancement motion of the system 10 occurs along a horizontal plane and that the shaking motion of the suspended load occurs in a vertical plane, the movement of the suspended load is composed of a vertical motion coupled with a horizontal motion. The horizontal motion is function of the arm length and the vertical shaking according to the expression:
  • the suspension system 10 according to the present invention can be made with a simple-pendulum kinematism.
  • the moving part is constrained to rotate -around the arm hinge point. Therefore, to the vertical movement of the suspended load a horizontal movement is associated, which is described by the following expression and a rotation ⁇ :
