Liebherr launches SmartGrip

摘要

Liebherr Maritime Cranes has launched SmartGrip, a new product for bulk handing mobile harbour cranes and allied slewing cranes. SmartGrip operates as an intelligent system that optimises grab filling rates in a self-learning manner and thus "provides a number of valuable advantages, including higher performance and zero overloads." It is available for retrofits. Data from ports around the world showed Liebherr that, on average, only 70% of grab capacity is used. Factors include sub-optimal grabbing angle and varying material density. For crane drivers, estimating material density and the right grabbing angle may be a real challenge and, in any case, their skill levels vary. In operation, the self-learning system automatically adjusts its behaviour by recognising bulk density, compression and granularity, as well as current frame conditions, such as depth of impression or type of grab.
