Usually in the open pit iron ore mining production will use electric shovel excavator to load the ore. This kind of equipment is relatively large, and the driving density is relatively high during the mining process. In addition, the slope in the mining area is steep, and the load capacity is relatively large during the transportation of iron ore.
