Step 5: Assembly
Final assembly of the LH 150 M Port E takes place at the factory in Kirchdorf. Well-tested and high-performance components are used. A high proportion of key components were manufactured in Liebherr factories.
Here, Viktor Maier assembles the drive group of the LH 150 M Port E. It is "the heart of the machine". Timing is crucial at this stage: the individual parts must be on site at the right time so that assembly can proceed smoothly.
Step 6: Set-up and testing
Once the machine has been assembled, commissioning and function tests follow. Jochen Sailer (left) measures and checks the complete range of functions: all components and parts are parameterised, adjusted and their functionality tested in interaction with one another.
The machine is usually ordered with a particular customer specification. The LH 150 M Port E for Bauma, for example, is equipped with a hydraulic, multi-adjustable driver's cab.
Only after a successful function and completeness check is the machine is dismantled.
Step 7: Labelling as electric drive technology
Although the Kirchdorf factory is steadily expanding its range of electric drive series, the blue sticker is being used here for the first time. The additional product labelling denotes electrically powered machines as a uniform identification symbol in the group of companies.
The LH 150 M Port E can produce a total system output of 614 kW thanks to the 400 kW electric motor and the ERC system.
8. Logistics
Jochen Schneider coordinates dismantling in Kirchdorf, transport to Munich and assembly of the LH 150 M Port E at Bauma. In Kirchdorf, the machine's handle and boom are dismantled first. Then the driver's cab is dismantled, the superstructure is lifted down and the undercarriage is disassembled. The team then prepares the individual parts of the machine for shipment. Ten trucks are needed to transport the individual parts to Munich. In some cases, heavy transportation is necessary – such as for the 60-tonne superstructure with cabin lift or the over 17-metre-long boom.
The challenge: parts that are dismantled last in the factory must first be assembled in Munich.
