Designed for secondary demolition work (separation or fragmentation of already demolished material, so as to make loading and transport easier). They stand out for the wide opening of the jaws, the considerable clamping force and the speed of the working cycle. They can separate the reinforcing rods from the concrete, so as to allow the material to be reused as scrap and aggregate. They are ideal for the demolition of flooring, perimeter walls and structures of medium height, including vertical structures, as well as for crushing at ground level.
