Key characteristics
Swap bodies share visual similarities with ISO containers but feature distinct differences that make them particularly suited for European intermodal transport. The most notable difference is their dimensions: swap bodies typically measure 45 feet (13.4 meters) in length, matching the size of standard road trailers and providing greater loading capacity for palletized goods compared to maritime containers.
The structure of a swap body consists of a lightweight metal chassis, frame, and tarpaulin covering. This construction makes them significantly lighter than rigid ISO containers, resulting in reduced fuel consumption during transport. While generally not as rigid as containers, swap bodies can still be stacked for efficient storage and transport.
Types of swap bodies
Different types of swap bodies are available depending on cargo requirements:
- Swap bodies with sliding curtains for easy side loading
- Swap bodies with inclinable shutters for specific loading needs
- Refrigerated swap bodies for temperature-controlled transport of perishable goods
Handling methods
Due to their non-rigid structure, swap bodies require specialized handling equipment. Two primary methods are used during transhipment:
Vertical Handling: The most common technique involves using cranes and vertical handling machines equipped with spreaders. These spreaders feature grapple clamps that lift the swap body from its lower frame, positioning it onto trailers or railway wagons. Once loaded, the bodies are locked to the frame using container-like securing systems.
Horizontal Handling: This method involves positioning a lorry and railway wagon side by side for lateral transfer of the swap body.
The versatility and efficiency of swap bodies make them an essential component of modern intermodal logistics, particularly for companies seeking to optimize combined road-rail transport operations while maximizing payload capacity and minimizing fuel costs.
