Extremely innovative, the compact design of the VMS-F20 model for frontal coupling. The horizontal pairing of two screening drums permits to double the operational capacity while maintaining the tool’s height unvaried and consequently the visibility from the cab that is not impeded from the bucket’s size. Hydraulically controlled from the cab, the material-size selection system enables the real-time size sorting from 25 to 60 mm. without stopping or slowing the work cycle down and without replacing any mechanical part.
