ABSTRACT:
A wire rope or cable stabilizing system for applying a balancing force to a suspended load to maintain vertical movement of the load perpendicular to the surface upon which the load is to be placed. The balancing force is effected to balance the lateral loading forces which may be applied to the suspended load such as may be due to, for example, the list or trim of a vessel, or the wind loading forces encountered when removing or replacing a hatch cover during a loading or unloading operation of a ship.
