In record time

The Swiss town of Etzgen is separated from Germany only by the Rhine and is close to Basel and the Argau. That means it has a good strategic location for the Swiss company Marcel Schraner AG. Founded in 1988 and run by the brothers Andreas and Daniel Schraner, the company specializes in the production of highly specific precision parts in small quantities for the food and chemical industries.

Bauberger AG transported, moved into place and installed a lathe and a milling center for the company back in 2006 and 2008, respectively. In 2015 came the third contract. In a total of four loads ex Elgg, Bauberger delivered a Mazak Integrex i-200 SU1000 complete with accessory parts plus the required heavy-duty equipment: four 6m long tracks, two 90t hydraulic cylinders with spreader bars, lifting links and shackles, transport dollies, hydraulic jack and wet drill.

During gantry setup, the already existing underslung crane with a lifting force of 6t was able to be used but not to lower the 13.9t machine into the basement. That task was performed by two hydraulic cylinders with a joint lifting and moving capacity of 180t. To reinforce the floor, Schraner AG placed a number of ceiling supports in the basement under the tracks beforehand. A further grinding machine had to be moved and leveled internally before the machine could be anchored at its intended installation site in the basement.

On the morning of the second day, the Mazak was anchored to the floor and pre-aligned. That afternoon, the last load of lifting and moving equipment was transported back. “We are extremely satisfied,” Daniel Schraner said, praising the Bauberger team for how well they worked together. The fine adjustment and commissioning was carried out by Wenk AG, Mazak general rep in Switzerland, and lasted just under two weeks, which is usual with such complex high-precision machines.
