Open �pa� containers were generally used for bulk goods such as sand and coal. Around 5, 300 units of the Eoskrt 022 �pa� container were built between 1960 and 1973, thus making it one of the most widespread types. In particular the small urban fuel traders quickly recognised the advantages of the open �pa� containers. Both the cargo handling and the portioning were made significantly easier, and it was possible to cleanly separate different types of coal within a single delivery. In addition to bulk goods that were not sensitive to moisture, the transported goods included bricks, roof tiles, construction and mining timber as well as bulky general cargo that could then be covered with tarpaulins.
