ABSTRACT:
Concrete crushing tongs comprise a frame-shaped first jaw of tongs (1) and a second jaw of tongs (2) which is connected to the first jaw of tongs (1) at a pivot joint (3). The two jaws of tongs (1, 2) each comprise concrete crushing portions (13, 18) with projections (14, 19). The concrete crushing portions (13, 18) of both jaws of tongs (1, 2) each project beyond cutting edges (11, 17) of the two jaws of tongs (1, 2) in a direction towards the corresponding other jaw of tongs (2, 1). Thus, the concrete crushing function of the concrete crushing tongs is separated from the function of cutting the reinforcement.
