Liebherr offers a wide range of automation systems that support modern high-efficiency production. The emphasis here is on economy, ease of use, quality and reliability in combination wïth a high degree of flexibility. The range of products comprises robotic palletisers, pallet handling systems, conveying systems, robots and emphasis on total System integration. With the Liebherr palletising cell as a basic module, ultramodern production with a decoupled process sequence can be realised. Standardised transport containers with basket technology facilitate a uniform approach to logistics as well as flexible future-orientated production. For the complete flow of material, the workpieces remain in a wire basket or workpiece carrier. This renders the interface between the machine and automation device uniform, providing a consíderable potential for cost reduction.

turn heightens acceptance among users. Not only that, it also has a decisive influence on the reduction of secondary processing times. As well as the optímisation of processing operations, these are becoming more and more important in terms of global competition.
Liebherr supports this process by means of simple time-optimised retooling and visualisation of the processes.

The Liebherr Automation Service has its headquarters in
Kempten Germany , and has a network of Liebherr service
centres around the world. The experts who man the customer hotline provide professional first-aid should help be needed. included in the services offered are the provision of spare parts, inspections, maintenance or modifications to systems. Since the products have a universal modular design, rapid provision of spare parts is assured, which means that periods out of use are kept to a minimum,
The Liebherr palletising cell was designed to be maintenance friendly throughout. All of the necessary lubrication points are supplied from a centrallubrication pump. As with all pneumatic components and bus modules, this is located on a maintenance unit that can be accessed easily from outside. Every palletisíng cell is supplied with a detailed
operating manual and service handbook that specifies the
service intervals and describes the work that needs to be
performed. As an option, Liebherr also offers the means of remote
maintenance. in this case, Liebherr experts perform a fault
diagnosis and rectify malfunctions online. Thanks to the use of commercially-available components, such as drive and control systems, Liebherr guarantees a high level of avaílability for the whole system.Two, three amd four unit cell Basket size 400 mm  Basket síze 600 mm Max. size of palletising ce11 Depends on size of transport pallet Size of transport pallet mm 600 x 400 800 x 600
