Liebherr has launched its new generation mobile harbour crane which it states represents a ground-breaking technical development and incorporates updates that make it truly “fit for the future.”
The company says that the most decisive innovation is the implementation of the “Master V” crane control system which, together with an even more efficient software architecture, provides the basis for integrating future assistance and partial automation systems into the crane in the long term.
Overall, Liebherr states that the new crane has become much more digital, networked, and smarter.
Examples of improvements highlighted by Liebherr include how the position of the outrigger system is now monitored by sensors and is thus part of the internal data processing, while the use of a new outrigger base in the field only requires a software update by Liebherr and thus offers more flexibility.
Another practical advantage is the variable use of digital IP cameras for better monitoring of the crane interior as well as the external crane environment. Plus, the new crane control is supplied by an independent power circuit, which means the whole crane can be continuously monitored by cameras and efficiently protected without the crane ignition being activated.
The Liebherr Pactronic 2.0 hybrid system is the second generation of a hydraulic drive system using hybrid technology and now an accumulator serves as an energy storage and provides support when needed by supplying additional, temporarily stored power.
There are also two operating modes, depending on the current work situation. In Boost Mode, the Pactronic 2.0 acts as a power amplifier, lifting speeds are significantly increased - without the aid of a larger or even additional engine for more power. This improves efficiency and delivers reduced cargo-handling time. The second option is Green Mode, which is designed to save fuel or power consumption and to reduce CO2 emissions. During the lifting process, the Pactronic supports the main unit to such an extent that less power is required by the main drive, despite the lifting speeds remaining the same. As a result, absolute fuel or power consumption and emissions are reduced.
