Application examples of large hydraulic bolt tensioning cylinders
During the mounting process of gas and steam turbines the main shafts are pre-tensioned with an ITH cylinder.
By their modular design the transport of large Bolt Tensioning Cylinders by cranes is simplified. The positioning of the change bushing of the large cylinders is positioned by ITH spring hangers (between crane and change bushing).
These tension anchor bolts M350 (13 7/9") at a rolling machine in a steel mill are tensioned by large ITH Bolt Tensioning Cylinders (vertical usage).
