The best LHM we ever made
The Liebherr mobile harbour crane series gets ready for the future. The new LHM is more digital, more automated and has a new look. A new crane control system, state of the art sensor technology and digital information transmission enable future assistance and partial automation systems. In addition, the Liebherr hybrid system Pactronic and the driver’s cab have been improved in line with customer needs.
Hybrid system Pactronic 2.0
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 store 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. This massively increases the efficiency of the crane. The LHM together with a Pactronic 2.0 hybrid system provides a reduced cargo handling time and achieves the same performance parameters as a comparable device with two main units.
Green mode
In this mode, the Pactronic 2.0 ensures up to 30% lower fuel or power consumption and reduced 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.
