A shaft-ring gripper is disclosed. The shaft ring gripper comprises a support structure having an axis and a plurality of gripping elements (9, 212, 213, 302) displaceable in a radially outward direction relative to the axis when the support structure, which has been lowered in an axial direction into an open upper end of a shaft-ring (218, 305) , is lifted, so that the gripping elements engage the inner wall of the shaft ring to lift the shaft ring together with the support structure. The shaft ring gripper further comprises guide members (9, 208, 214) on the support structure to guide the support structure into the open upper end of a shaft ring when the support structure is lowered. |
