Justification of design factors for linear cable-stayed section of overhead wire rope conveyor of RopeCon® type

The mining industry of late years both in Russia and abroad has increased the number of long and high-duty belt conveyors employed in open pit mines to convey minerals to warehouses or processing plants. An alternative to the customary belt conveyors can be overhead wire rope conveyor RopeCon, which possesses some important advantages: smaller weight per unit length of the conveying line; designability of the conveyor line on a rough terrain; 4 times lower power intake of the conveyor drive. The former two advantages are connected with the design features of the cable-stayed structure of the overhead wire rope conveyor, which sometimes enable setting up cable support towers at a spacing up to 1100 m. The article describes a linear section of the overhead wire rope conveyor RopeCon, which includes a three-strand cable-stayed system composed of two upper load-bearing cables and four guide ropes for travelling rollers of loaded and empty branches of the conveyor. The problem connected with the determination of the cable-stayed system parameters and distribution of loading generated by the belt weight, cargo on the belt and by the weight of the travelling rollers between the strands of the cable-stayed system to ensure firm adherence between the cables and arms of the main frames is solved as a case-study of the loaded and empty conveyor. The analytical expressions are obtained to find the required safety factors for the reliable adherence between the cables and arms of the main frames at different loads of the conveyor belts, and to determine the weights per unit lengths of all cables and their tensions.
