For the mobile harbour crane range Liebherr has developed an intelligent system which optimises grab filling rates in a self-learning manner. In a comprehensive study, Liebherr collected real bulk handling data of different crane models. Complex data analyses showed that – on average – only 70% of the grab capacity is used, mainly due to suboptimal grabbing angles and a varying material density. Based on these findings, SmartGrip ensures that the full capacity of the grab is utilised. By recognizing bulk density, compression and granularity as well as current frame conditions like depth of impression or type of grab, the system automatically adjusts its behaviour. As a result, this innovative system has the potential to significantly increase turnover. Additionally it prevents overloads, saves fuel and reduces the stress for crane drivers.The intelligent grabbing technology SmartGrip represents an evolutionary step in highly efficient bulk handling and provides various advantages to ports and terminals.
