【正文】 de and container transshipment are making the stacking arrangement and operation management of containers more difficult； if the RTG is not tracked， it is inevitable that the container may be misplacedsuch a mistake will result in expensive loses。 development of RTG is being hindered due to the shorting of gantry it now bees critical to developing gantry automation while trolley and hoist of RTG has been automated to some extent； control of gantry usually is difficult to reach for large span RMG／QC In the case that gantry on seaside and landside don t travel at same speed， the crane will present skew phenomena and its performance will be degraded. such as “critical path method” to manage the operation more efficiently. 2. Autosteering of gantry for RTG No maker how high and quick the RTG is， by making use of the “vitual rail” from GPS， excellent gantry auto—steering of RTG could be realized thus the RTG Could travel very straight like an RMG and potential gantry collision with other RTG／ vehicles is eliminated。 operators also could be relieved from the fatigue of manual steering. 3. Gantry auto traveling of RTG with position data (initial and destination position) from the GPS system the RTG could have gantry auto traveling function at the same lane. 4. Fault free operation of RTG By bining gantry position from GPS and positions from trolley and hoist an “emap” of containers on the yard could be set up The RTG could be so designed that its operation is only possible when the directed container from control center is coincide with the real container(by paring the positions)． 5. Automatic container management with gantry／ tro1ey／ hoist position information of the RTG messages including the operation status， current position etc could be sent all the time to the control center； In that way stacking profile of the yard could be continuously updated and manual operation statistics could be reduced to a minimum； 6. Synchronous control for large—span RMG or QC large span RMG or QC is liable to having slipping problem during gantry t raveling which in turn resents skew ph
