Unloading a Container (Devanning)
January 21, 2025
What is devanning?
Devanning is the English term for unloading cargo from a sealed shipping container. It is also referred to as stripping, unloading, or emptying the container. This process plays a crucial role in warehouse and logistics management and increasingly uses digital technologies. It involves the systematic removal of individual items from the cargo space of sea containers.
How are containers unloaded?
There are several methods for unloading sea containers. It is important to choose an approach that suits the specific warehouse facilities, as inefficient processes can lead to delays in handling and delivering goods.
Step 1: Park the vehicle safely at the destination. This includes using an emergency brake and ensuring that the forks of equipment or pallets do not stick out. Special handling skills are required to ensure a smooth and effective unloading process.
Step 2: Unloading at dock level. This is usually done using forklifts. The process begins by positioning the container on a truck, which then drives to the warehouse and places the container at the loading dock.
Inexperienced workers may cause material damage or harm to facilities and could suffer injuries. Therefore, proper staff training is essential.
The importance of Warehouse Management Systems (WMS)
Warehouse Management Systems (WMS) play a key role in automating logistics processes. They support cargo management, inventory tracking, goods monitoring, and reporting. This helps logistics companies work more efficiently and control costs.
By using a WMS, containers and their contents are tracked from the moment of unloading until storage or further shipment. This increases accuracy and improves planning within the supply chain.
How long does it take to unload a container?
Unloading a 40-foot container takes on average two hours. Factors such as equipment quality and the experience of the logistics provider can influence this duration.
Where are containers unloaded?
Unloading takes place at:
Warehouses for full container loads (FCL)
Container freight stations for less than container loads (LCL)
What is LCL?
Less than Container Load (LCL) refers to cargo that does not fill an entire container. It is an efficient solution for smaller shipments.
Equipment for unloading sea containers
Professional equipment makes the unloading process more efficient and safer:
Pallets: Carry the weight of the goods and prevent movement during transport. They come in various sizes and materials such as wood, plastic, or steel. Pallets can be single-use or reusable depending on the purpose.
Counterbalance forklifts: Suitable for moving heavy loads. Operators use hand controls, steering wheels, and cameras to work safely and precisely.
Truck liftgates: Electrically operated systems that facilitate easy loading and unloading of heavy items in and out of trucks. They are especially useful when no forklift or loading dock is available.
