With its new mobile harbour crane, Liebherr presents groundbreaking technical developments and updates that make the LHM product series fit for the future. The decisive innovation is the implementation of the “Master V” crane control system. Together with an even more efficient software architecture, this forms the basis for integrating future assistance and partial automation systems into the crane in the long term. Overall, the crane will become much more digital, networked, and smarter.
The position of the outrigger system is now monitored by sensors and thus part of the internal data processing. 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. The new crane control is supplied by an independent power circuit. This means that the crane can be continuously monitored by cameras and efficiently protected without the crane ignition being activated.
The Liebherr Pactronic 2.0 hybrid system represents the second generation of a hydraulic drive system using hybrid technology. An accumulator serves as an energy storage and provides support when needed by supplying additional, temporarily stored power. The second generation of the Pactronic offers the operator a choice of two operating modes, depending on the current work situation:
Boost mode
In this mode, the Pactronic 2.0 acts as a significant power amplifier. Lifting speeds are significantly increased – without the aid of a larger or even additional engine for more power.
Green mode
This mode 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.
