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.
Implementation of the new "Master V" crane control system, that forms the basis for integrating future assistance and partial automation systems.
A deep system integration of sensors and drives, that makes the crane significantly more digital, networked and ultimately smarter.
Sensor system is integrated into the crane's CAN bus system, which allows individual components to communicate and interact with each other.
The colour compositions of the latest LHM generation combine the classic Liebherr yellow with new accents in black, grey and white. The agile-looking design reflects how long-standing tradition and corporate values combine with advanced technologies. The modern colour scheme gives the machines a distinctive look and instant recognition.
The blue accent in the colour composition and also the blue symbol next to the crane type, give all alternatively powered machines a distinctive look in the future. This allows all future LHM customers to directly communicate advanced and environmentally friendly crane technology to their stakeholders.
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:
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.
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.
The redesign of the LHM operator's cab focuses on the crane operator. Thanks to the new coupling of joystick and armrest, not only does the driver's comfort increase, but the control of the crane also becomes even more precise and safe. With the new integrated touch panel, all crane functions can be selected clearly and intuitively, which greatly simplifies the operation of the crane. An integrated bottle cooler provides cool drinks - even on warm days. A revised air-conditioning concept significantly increases the well-being of the operator, whether air-conditioning or heating. It also ensures that fogged windows are quickly dehumidified, thus providing a clear view and more safety.
