ELECTRODE SLIPPING DEVICE

An electrode slipping device (1) comprises an upper holder ring (2) and a lower holder ring (3) having one or more clamping assemblies including a clamping shoe (4) and a clamping device(5). The clamping shoe (4) is operable between a clamping position and a release position. The clamping device (5) comprises a frame element (6) fixedly attachable to a holder ring (2, 3) to be stationary in relation to the holder ring, a cylinder portion (7), a plunger (8) and a pressing spring (11) arranged inside the cylindrical housing (9) of the plunger (8) for urging the plunger (8) to- wards the clamping shoe (4) and for pressing the clamping shoe (4) against the electrode (E). A tension bar (12) is releasably attached to the end plate (10) of the plunger (8). A piston element 15) is arranged movable inside the cylinder portion (7) to form a hydraulic power means (16). The clamping device (5) com- prises one and single tension bar (12) arranged centrally in relation to the frame element (6), the plunger (8), the pressing spring (11) and the piston element (15).
