0 ton column press

Tensioning of column

Challenge:
The column press for the manufacture of forged aluminum truck rims is 60 years old and is insufficiently pre-loaded. It
lifts at the lower and upper shaft, the tools wear out too quickly and the columns are overloaded. The columns should be re-used, but the
threads are badly deformed.

Solution:
The Superbolt® tensioners used are manufactured to order and fit right away. The press stands on its columns, therefore split tensioners are
used on the lower shaft.

Specification:

 4 pcs tensioner MT-S580x12/W-spc
 4 pcs split tensioner MT-S580x12/W-spc

Remark:
The Technical University Dunaújváros helped with the preparation and reconstruction of the whole project. The downtime of the press was
minimized to two weeks.
