Breaking up foundations, subsoil and concrete pavement

摘要

The comminution tool (30) is used for breaking up subsoil, foundations, concrete pavement etc. It uses a weight which may be repeatedly lifted up and allowed to fall to hit the material underneath. The comminution tool may be carried on a utility vehicle, e.g. a bulldozer, running on endless tracks. Several weights (G1,2,3) may be used, which may be lifted up and let fall together or one at a time. The drive mechanism includes shafts (50) and chain drive mechanisms.
