The latest product line features a new crane control system (Master V), advanced sensor integration, and digital information transmission.
The position of the outrigger system is now monitored by sensors, forming part of the internal data processing. Using a new outrigger base in the field only requires a software update by Liebherr.
Digital IP cameras are used for better monitoring of the crane interior and the external crane environment.
An independent power circuit supplies the new control, meaning the machinery can be continuously monitored by cameras and protected without activating the crane ignition.
The new series also features the Liebherr Pactronic 2.0 hybrid hydraulic drive system. An accumulator serves as energy storage and provides support when needed by supplying additional, temporarily stored power.
Pactronic 2.0 offers two operating modes: Boost and Green. The former acts as a power amplifier, increasing lifting speeds. Liebherr says the new LHM with Pactronic 2.0 achieves the same performance parameters as a comparable device with two main units.
The Green mode has been designed to save fuel or power consumption and reduce CO2 emissions. During the lifting process, Pactronic 2.0 supports the main unit to such an extent that less power is required by the main drive, despite the lifting speeds remaining the same.
By setting the individual lifting height, the power output of Pactronic 2.0 is adjusted accordingly. The additional energy is distributed over the entire lifting process. The new Pactronic reacts to changes in the outside temperature and the accompanying change in pressure in the reservoir.
The cabin of the new LHM has also been redesigned to provide increased comfort, precision, and safety.
"With its new mobile harbour crane, Liebherr presents groundbreaking technical developments and updates that make the LHM product series fit for the future. [...] Overall, the crane will become much more digital, networked, and smarter," the company wrote in a press release.
