The fastenings of steel cables for loading containers are subjected to high degrees of stress, resulting in the use of robust screw-type jaws. The systems currently installed on such cranes for fixing cables are fixed screw-type jaws. This is a much more versatile and flexible system that is based on a wedge mechanism that allows automatic and instantaneous (remotely controlled) actuation. The assembly includes the sliding clamps, actuation of said clamps, necessary additional guides and a tensioning device for adjustment of the cables. This solution makes it possible: to carry out the cable-change operation with the boom raised, thus allowing manoeuvring of the vessels and operation of nearby cranes; to reduce cable-replacement times; and to use the anchoring element (clamps) + tensioning device as a mechanism for adjusting the length of the branches. It is possible instantaneously to correct possible spreader misalignments.automatic system for guiding, retaining and adjusting cablesautomatic system for guiding, retaining and adjusting cables.
