Abstract: Movable pulley head assembly for a lateral spreader movement, where the lateral movement of the spreader is carried out directly on hoist pulley assemblies, the assembly including structurally rigid bridges where a beam of the bridge is long enough for the travel of the mechanism, cross members attached to pulley heads, where each cross member supports a bridge at each end by means of elements allowing relative movement between bridge and cross member, where the cross members can be extended outside the bridges to serve as support for other elements or mechanisms, the assembly further including worm screws for the lateral movement of the spreader.

Abstract: The fastenings of the wire ropes for loading containers are subjected to huge stresses, making it necessary to use screwed-in robust grips. The systems currently installed in these cranes for fixing ropes are fixed, screwed-in grips. A much more versatile and flexible system is presented that is based on a wedge mechanism which allows automatic and instant actuation (remotely controlled). The assembly includes the sliding clamps, the actuation of these clamps, necessary additional guides and tightening device for tightening the ropes. This solution allows: Performing the rope changing operation with the jib hoisted, thus allowing the maneuvers of vessels and the operation of contiguous cranes. Reducing the rope replacement times. Using the anchoring element (clamps)+tightening device as a mechanism for tightening the length of the ends. Possible misalignments of the spreader can be corrected instantly.

Abstract: The invention relates to hydraulic motors for actuating and controlling an anti-swing system in container-handling cranes. Container-handling cranes pose the following problem, namely that, when the trolley moves, the cables supporting the load spreader oscillate longitudinally in relation to the aforementioned movement. Systems currently used to reduce said swinging movement are inconvenient because (i) they comprise numerous power transmission elements, thereby generating maintenance problems, and (ii) the main two functions thereof are performed separately, i.e. movement transmission and oscillation reduction. The aforementioned problems can be resolved with an autonomous, independent drive system using hydraulic motors, thereby rendering the power transmission drive chain simple, robust, reliable and easy to maintain. In addition, the motors perform the main functions simultaneously, i.e. producing the movement and reducing the oscillations.
