I never work on the same type of engine twice in a row. During the next shift, for example, an "exotic" D924 is waiting for me. Previously, I used to work on an assembly line, as well. But those were hours of the same movements, over and over again. I'm happy that it's completely different here.
Monday 7:00 a.m. In the spotlight is our engine assembly area in Ettlingen: Trolleys with half-finished engines are swivelled, hoisting cranes are whirring and pneumatic screwdrivers are creaking. Sandra has just fitted the last cylinder head on an overhauled diesel engine D936 in the assembly cycle 70:
The most exciting thing about working here is the variety," she says.
This is not surprising: The variety between the in-line 4 and V12 engines from Liebherr's own production is enormous. There are currently over 600 active engine configurations to be remanufactured at Liebherr-Ettlingen. These engines are installed in Liebherr earthmoving machines and cranes of different types and generations. By remanufacturing, they are all given a second life after several thousand hours made during their "maiden voyage". And our portfolio is constantly expanding. With each new EU emission standard, further engines add to it. Sandra and her colleagues show growing appetite for technical progress. They remain adaptive and flexible at all times: "Of course each colleague specialises in certain types of engines, but in fact, each of us can assemble a major part of our portfolio range."
State-of-the-art tools facilitate Sandra's daily work: "We no longer have to check each required torque of basic engines by hand. With our pneumatic screwdrivers, we set the engine type in advance. The correct torque is then automatically adjusted, based on the digital assembly instructions," Sandra explains.
In addition to the Reman business, Liebherr-Ettlingen also manufactures new engines in small batches. This also means project-based work: "When assembling prototypes for small batch series, permanent coordination with customers' engineers is required to discuss potential improvements. We are also involved when it comes to process optimisations. This includes best arrangements of tools and the punctual supply of single parts for mounting".
It’s for sure that boredom will not come up with such manifold activities. For now, Sandra is looking forward to "her" D924 to come tomorrow.
