The mobile, pivotable belt conveyors are conceived primarily for production processes in which rejections occur frequently. So often in production the problem arises that when a plant is started, qualitatively inferior products arise. By virtue of their high degree of manoeuvrability, the belt conveyors can be manually pivoted to the side and the product shunted off to another location. The pivoting device is designed for all sorts of processes, because the transported material intake height is variable, being possible even a height of only 300mm.
