ABSTRACT:
The breaking tongs with a tong body (7) for receiving two tong parts (1, 1'), each pivotable about its own rotation center (2, 2'), and spaced from the rotation center the tongs are subdivided into a tong lever (3, 3') for the force action and a cutting lever (4, 4') for exerting the breaking force. The tong protuberances (12, 61, 63) are detachably mounted on the cutting levers. In the vicinity of the tong cutting edge (4, 4') separating blades (6, 6') can be provided for cutting reinforcements. The detachable tong protuberances (61, 63) can be detachably fixed in a protuberance bed (60), which is detachably arranged or shaped on to the cutting lever (4, 4'). A plurality of tong protuberances can form a working profile, which differs as regards the breaking action from another working profile formed from the same or a different number of tong protuberances.
