System of floating Cranes harmonized with counterweight, for transfer of Cargo containers

摘要

The Invention is based on the use of Gantry cranes, installed on a ship with flat roof, with Rails for the longitudinal Movement of the Gantry Cranes. Gantry Cranes are used to move containers from the band where lies the container Feeder Vessel towards the Band, where it is located the landing units and vice versa.The Movement of containers by Gantry cranes, is conducted in a Harmonized Way, i.e., during the work of transfer of loading and Unloading, the Gantry Crane has a cargo AFT on the Starboard Side,The Bow has its cargo in the Port Side; in order to offset the list produced by the Asymmetric Loading (Transverse Harmony); when the Gantry Crane AFT, with a High LoadThe Bow has a Lower load; in order to offset the loss of stability of being produced by the location of heavy Weights (vertical Harmony); both Cranes are positioned longitudinally and Fore AFT Movement between these or vice versa.Try to compensate the Trim of the vessel; in case of requiring additional weight for load compensation asymmetrical longitudinal, transverse and vertical, uses a Dynamic System of Ballast tanks, located in the lower deck of the ship; all this in order to reduce any movement to Fecte Loading and Unloading of containers. The system comprises
