For this type of container, the limit in terms of weight is around 26-28 tons. What sets the limits for this type of equipment is its width. Depending on the way of loading/unloading the cargo, acceptable Open Top container dimensions vary. These are limited by the upper rails that are 2.2-metre wide, which limits any cargo exceeding this width. OT container operations are performed if loading of the cargo is carried out through the door and its width does not exceed the limit on the upper part of the container.
