2. Description of the Related Art In recent years, various crushing attachments have been developed for further finely cutting rebars, steel frames, pipes and other debris from dismantled reinforced concrete or steel structures (buildings, etc.). Many of them are extremely suitable for crushing concrete lumps or cutting rebars and steel frames. However, there are few suitable ones for dismantling structures such as tanks and towers made of iron plates and the like.
