In a port container yard, rubber tired gantry crane (RTG) are majority which perform handling the container from a chassis to a yard, or from a yard to a chassis. It has been very difficult to realize automated RTG, because RTG is a large low rigidity crane mounted on rubber tires. We developed new technologies. (1) Image sensors installed at corners of spreader to detect container position directly by the CCD camera. (2) Automatic landing control, anti-skew control, sway velocity observer system. We converted into actual automated RTG and experiment automatic operation system. As a result, we obtained the utilization prospect of automated RTG.
