Tank Trailers

High-Volume Precision for Liquid & Sensitive Cargo

Q: How does Davi ensure precise rolling for non-cylindrical tank trailer geometries like oval or multi-radius shapes?

To manage the complex geometries typical of oval, square, or customized tank trailers, Davi integrates the advanced iRoll eXtreme control system with automated material handling accessories. This high-end automation precisely controls single and multi-radius shapes while utilizing swinging overhead supports—essential for long, flexible shells—and double-articulation side supports to maintain geometric accuracy and prevent structural collapse during high-volume cycles. This combination guarantees that complex geometries meet rigorous transportation safety standards while maximizing throughput and ensuring exceptional repeatability for mass production.

Q: What solutions does Davi offer to protect delicate materials like polished stainless steel or aluminum from surface defects?

Delivering flawless surface quality is critical when processing sensitive materials like Duplex, aluminum, or polished stainless steel for the liquid and hazardous cargo sectors. Davi addresses this by equipping bending lines with hardened and polished rolls, specialized brush tables, and rubberized components that eliminate the risk of scratching or marking during the process. Furthermore, the innovative MCE e-POWER fully electric plate roll offers a completely oil-free operation, ensuring a contaminant-free production environment that preserves both the structural and aesthetic integrity of high-value cargo tanks.

Q: Can Davi plate rolling machines handle extra-wide plates to minimize longitudinal welds in tank trailer production?

Yes, Davi engineers highly customized solutions capable of bending exceptionally wide sheets up to 12,000 mm (472 in), far exceeding standard market offerings. By enabling the fabrication of wider shells from a single plate, trailer manufacturers can significantly reduce the number of circumferential welds required, directly cutting down cycle times, non-destructive testing costs, and assembly complexity. This engineering capability ensures optimal structural integrity for long tank trailers while driving down the total cost of ownership in high-volume production lines.

Q: How does Davi automation solve the challenge of high-volume mass production for tank trailer manufacturers?

Davi optimizes mass production efficiency by transforming the stand-alone rolling machine into a fully integrated, highly automated production cell that streamlines internal material flows. Our systems utilize synchronized logistics—including automated infeed conveyors, centering devices, crowning compensation systems, and inboard ejectors—to minimize manual intervention and dramatically reduce cycle times. Backed by full Industry 4.0 connectivity via OPC-UA protocols, these lines seamlessly interface with factory MES and external machinery, allowing manufacturers to maintain operational continuity and secure a highly productive, scalable manufacturing pipeline.

The tank trailer industry demands special geometries and high-throughput production to safely transport liquids, gases, and hazardous materials. Davi provides rolling solutions specifically designed for the typical cylindrical, square, or oval shapes of these trailers, ensuring structural integrity and a competitive edge in mass production.
