FAQs

Frequently Asked Questions About the 20-40 Spread Chassis

What container sizes does the Spread Axle chassis support?

It is built to carry one 20’ loaded, one 40’ loaded, or two 20’ empty ISO containers.

Why choose a Spread Axle over a standard tandem axle?

The 109″ axle spread helps improve weight distribution across axles, which can enhance braking stability and comply with bridge law requirements in certain regions.

Can this chassis be used for long-haul applications?

Yes, it’s well-suited for long-distance hauling with high load reliability and durable suspension.

Is the chassis equipped with automatic tire inflation?

Yes, it includes a PSI – ATIS system that monitors and maintains proper tire pressure automatically.

Is it customizable for fleet needs?

Yes, bolt-on components like twist locks, bumpers, and landing gear brackets allow for easy customization and serviceability.

Is the Spread Axle chassis compliant with U.S. transportation regulations?

Absolutely. It meets or exceeds TOFC, AAR, DOT, FMVSS, ISO, SAE, and TTMA standards.

Testimonial

“Before Trend, we treated equipment like a sunk cost and kept extra chassis around just to stay flexible. Now we’re running leaner and getting more out of less. The dual-size chassis cut down mismatches, we’ve cleared out yard clutter, and we’re not wasting money on empty moves. It just works better—and costs less.

Unlock cost savings through smarter fleet utilization. Trend’s advanced chassis are built to boost uptime, cut costs, and deliver real ROI. Use our calculator to see the impact.

Boost Productivity
Reduce the number of chassis swaps and repositioning to move more loads and save time.

Smaller Fleet, Higher Utilization
Replace single-use 20’ chassis and get more value from every asset.

Save Valuable Ground Space
Retracted 20’/40’ chassis take up to 25% less space, which is critical in crowded terminals.
