The task of operating a grab ship unloader driverlessly and fully automatically was long regarded as impossible. With the combination of a real-time 3D LiDAR laser scanner, highly accurate RTK GPS system for machine positioning and an internally developed leading-edge control technology, however, iSAM was successful in solving the task. Four unloaders in Hamburg and three unloaders in Rotterdam are currently equipped with this technology.
Operation of all equipment from one central control station, i.e. minimum stress for the operator in the control room
Real-time determination of the grab’s position
Automated unloading even under the hatch coaming
Permanent update of data for the energy and position model for the grab’s moving path
