What Are Open Top Containers?
Dec 05,2023

Within the container industry itself, there are several different containers that can be commercially used for shipping. From wholly refrigerated units called reefers to custom made units for factory and industrial parts, there is a type of container for almost every single good that can be shipped.

An important point to keep in mind is that containers are generally of fixed dimensions. The height and breadth are consistent across most widely available units, while the length varies between either 20 feet or 40 feet.

However, what happens when the cargo to be shipped is too tall for the container? Or it cannot be loaded through the doors at either end of the container? For such goods, cargo ships and general carriers may not be an option.

This is where the Open Top Container comes into picture. It is an important container unit that is provided by most shipping lines and logistics companies around the world. It offers enables several industries to function by allowing a larger variety of goods to be transported.





Open Top Containers (OTCs) are a type of container unit that is unique in structure. It is characterized by an open top that is covered by a tarpaulin. It is specifically built to store large unwieldy cargo that cannot be transported by conventional containers. In addition to the open-top, it can also be accessed through doors on either end of the container that allows normal goods to go through.

Most containers are manufactured from steel to provide structural strength despite having a discontinuity at the top. Reinforcements run along all sides to keep the shape rigid and also to support loads from all directions.

The cover on top and the doors can be locked and are also sealed by the customs at a port. While other containers are difficult to tamper with due to the seal placed on the locks, there is an additional challenge of sealing open-top units.

For this reason, heavy-duty covers are used and are kept in place by clamp locks that cannot be unlocked without a special device. Additionally, these containers are monitored while in transit to prevent theft or vandalism to the unit.

Loading and unloading operations are carried out in a manner similar to any normal container. Spreader cranes are used to lift the unit up while container stackers are used within the yard for arrangement.



In most cases, the cargo within fits well within the container dimensions, and so, the tarpaulin remains horizontal. In such cases, the container can be stacked under other units without any structural problems. However, if the cargo is large, bulky, and does not fit into the container, then some portion of it will stick above the container sides.

In such cases, the container cannot be stacked. During shipments, such container units are kept in a separate location to ensure that they are not damaged.

Similarly, at the container yard, open-top containers are placed in a different location to prevent accidental stacking. For moving OT units with cargo that sticks above the roof, only forklifts or vertical stacking cranes can be used.

Due to the novelty of OT containers, they are not easily available in the market. Shipping lines provide these facilities around the globe and even offer special services to keep your cargo safe and secure throughout the journey.

Due to the lower number of such units in circulation, they cost slightly higher than conventional containers. Also, the cost varies depending on the type of cargo you wish to transport. Cargo that stays entirely within the unit is typically charged much lesser compared to cargo that extends beyond the roof cover.



In conclusion, as industries adapt to the dynamic demands of global trade, the open top container emerges as a beacon of innovation, offering unparalleled versatility and efficiency in shipping and storage. Its unique design, efficient cargo handling capabilities, and weather-resistant features make it the ideal solution for businesses looking to streamline their operations and cut costs.
