LIEBHERR has announced it is integrating the cross-manufacturer MiC 4.0 BUS communication standard into its Generation 8 wheeled excavators.
The aim is to enhance the safety, efficiency and cost-effectiveness of specialised attachments.
The standardised interface enables the automated exchange of data between the machine and compatible attachments. Liebherr explained that this simplifies their integration into the work process, reduces the workload on operators, and minimises sources of error.
When a MiC 4.0-ready attachment is coupled to the machine, information such as the attachment type, serial number and operating parameters – including oil pressure and flow rate – is automatically transmitted to the machine.
Until now, Liebherr said that connecting attachments such as tiltrotators to wheeled excavators has often involved ‘considerable effort and prolonged machine downtime’. Necessary modifications to the carrier machine could also have implications for existing approvals and conformity assessments, such as CE marking. The MiC 4.0 BUS reduces this effort and makes it easier to integrate attachments into site operations.
The digital connectivity of the MiC 4.0 BUS is also tipped to lay the foundation for more transparency regarding the use of attachments within the fleet. Information on usage, operating hours or maintenance status can in future be viewed via the MyLiebherr Maintenance & Performance customer portal. This gives fleet managers a better overview of how their attachments are being used.
