A hydraulic machine made up of:

Clamps to close and carry the electrode column for prolonged periods of time.
Lever clamping collar and cylinder to get a correct assembly and to set the required torque.

This system allows the unscrewing of previously jointed electrodes.
The electrode joining operation is driven by a PLC and requires the job of only one person. The display shows the tightening torque that has been reached at the end of the operation.
