Increased activities of the bulk handling industry world wide necessitate conveying even greater quantities of bulk and large lump materials. This demand has accelerated the development of realistic solutions for belt conveyor that couple robust strength with working flexibility, resulting in even higher belt speeds. In particular, research into solutions for the most critical area of the conveyor, that of the loading zone, has resulted in the development of the suspended roughing sets. These suspended sets are quickly and simply installed, and allow maintenance to be performed on them without shutting down the plant. For these reasons, the suspended system has resulted in their increasing use in the most diverse applications.
