How Titan Trailers Builds Stronger, Smoother Cargo Containers

A design for a cargo trailer shaped like a rounded tube made from flat and curved aluminum panels that are welded together to create a smooth, unobstructed interior.

What it covers

This patent describes a method for constructing a quasi-cylindrical cargo container by joining curved and flat aluminum panels. The design uses two semi-cylindrical shells connected by flat extension panels to create a tube-like structure. The manufacturing process involves using external collars to compress the joints between panels while they are welded, ensuring a tight fit. The resulting container is unique because it lacks internal ribs or reinforcing bands, providing a completely smooth, hollow interior for cargo.

What it doesn't cover

• —Does not cover standard rectangular or box-shaped cargo containers.
• —Does not cover containers that rely on internal support ribs or annular bands for structural integrity.
• —Does not cover containers made from materials other than those described, such as non-metallic composites.
• —Does not cover non-welded assembly methods like bolting or riveting.

The clever bit

The invention uses a specific assembly sequence where external collars compress the joints while the container is rotated, allowing for precise welding of both inner and outer seams without needing internal structural support.

Why it matters

In the heavy-duty trucking and logistics industry, interior space and durability are critical. Traditional trailers often use internal ribs that snag cargo or limit volume. By creating a smooth, rib-free interior, this design allows for easier loading, cleaning, and more efficient use of space, which is highly valuable for bulk haulers.
