Bulk (or bulk cargo) containers have three loading hatches in the roof, each of a diameter of approx. 455 mm (1 3/4′). The distance between the hatches (center to center) is 1.83 m (6′). On the door side, there are two discharge hatches, which are sometimes equipped with short discharge tubes for guiding the bulk cargo. Alternatively, two unloading hatches may be mounted in the doorways, for emptying the containers.
Such containers may also be used for general cargo. Lashing rings are mounted on the top side rails to secure the cargo. Some bulk containers are equipped with forklift pockets, which allow forklift trucks to handle them.
