During the production process, Pit-Radwar S.A. uses large and heavy profiles and rods from non-ferrous metals. Limited storage space and a need to automatize transport of materials to production line resulted in ordering TwinTower®, equipped with crane. Compact construction of the rack uses only 24 sq. m. of the storage building, allowing storing loads up to 22 tons in 44 shelves of total area of more than 164 sq. m. Crane, incorporated into racks body, allows for unloading supplies from a truck directly into shelves. The system is also adapted to operate with gantry, to improve and shorten time of transporting of materials to be cut.
