Stud Turning Devices

Resulting from the experiences with our stud tensioning machine, we have developed stud turning devices that enable the weight compensated  automatic unscrewing and screwing in of the reactor pressure vessel bolts. We can attach up to 8 individual rotating devices to a support frame, which simultaneously unscrew and screw in the RPV screws.

In addition to this, we also provide storage racks and transport equipment for transporting the RPV bolts and cover nuts within the reactor building. These guarantee quick and easy handling and at the same time offer protection against damage during interim storage during inspection and maintenance times. We adapt all facilities to customer-specific operating conditions.
