What is the primary function of a chassis in container transportation?

The primary function of a chassis in container transportation is that it serves as a vehicle specifically designed to transport containers. Chassis are typically made with a flatbed design to securely hold containers during transit, allowing for efficient movement across various modes of transportation, including road and rail.

This functionality is essential in the logistics industry, as it allows shipping containers, which hold cargo, to be easily moved from one location to another, particularly from ports to distribution centers or directly to customers. Chassis are designed to support standard container sizes, ensuring stability and safety during transportation.

The other options do not accurately describe the role of a chassis in container transportation. Lifting equipment is used for raising and lowering containers but is not involved in transporting them. A storage unit refers to facilities where containers can be kept when not in transit, and a road trailer for passenger vehicles does not pertain to the transportation of cargo containers.
