The system includes a first elongated flexible element (92) having first second ends, the first end of the first flexible element being connectable to the force generating component (94), and a second elongated flexible element (80) having a first end and a second end, the first end of the second element being connectable to the load (64). A force modifying member (90) rotatable about a fixed axis is provided and includes first and second outwardly facing surfaces of predetermined lengths, curving about the axis, to which the second ends are respectively attached. The first and second surfaces are dimensioned such that rotation of the member about the axis in the first direction causes one of the elements to be wound onto its respective surface as the other element is unwound from its respective surface thereby varying the force moments about the axis so to render the biasing force on the load generally more uniform. |
