The containers for intermediate storage are used for the in-company logistics of the bulk material. They are primarily applied in the plastics processing industry for de-bagging beside the converting machines or as a buffer between the silos and the converting machines. The containers can be moved either by a stacker crane, an elevating truck or a tower crane. For this purpose they are ruggedly built with a base out of steel, although they are still very lightweight because of the aluminium construction.
