Knott Trailer Torsion Axle – 3500KG Heavy-Duty Tandem Axle Chassis with 250×40 Brake Drum for European Farm & Cargo Trailers
Building a robust farm trailer or heavy freight trailer that demands exceptional load capacity? This Knott trailer torsion axle tandem chassis is rated at 3500KG and built around the proven 250×40 brake drum platform. Supplied as a fully integrated axle-and-frame foundation, this heavy-duty assembly eliminates the complexity of fabricating separate running gear—giving trailer builders across Russia and Europe a faster route from workshop to road.

Pre-Assembled Chassis Platform – Built for Productivity
Where conventional trailer construction involves sourcing axles, suspension, brakes, and mounting hardware separately, this 3500KG tandem axle chassis arrives as a single, pre-engineered module. The twin Knott trailer torsion axle units are already positioned, squared, and mated to 250×40 brake drums at both ends. Trailer manufacturers simply bolt or weld their cargo bed, drawbar, and mudguards directly onto this ready-made platform—cutting fabrication time and eliminating alignment errors that plague self-built running gear.
Applications Across European & Russian Heavy-Duty Sectors
The 3500KG load rating and generous brake swept area of the 250×40 brake drum make this tandem axle chassis a natural fit for demanding tasks across the European and Russian trailer markets:
- Farm Trailers & Agricultural Tipping Trailers – Handles heavy loads of grain, silage, fertilizer, and field equipment with the durability required for daily agricultural use.
- Heavy Cargo Trailers & Enclosed Box Trailers – Provides the braking confidence and axle strength needed for dense freight, building materials, and palletised goods.
- Industrial Utility Trailers – Serves as the backbone for workshop, factory, and plant-internal trailers that must move substantial payloads on uneven yards.
- Livestock Trailers & Animal Transport – The tandem spread and independent torsion suspension deliver a smoother, more stable ride for moving cattle, pigs, or horses.
- High-Capacity Caravans & Large Campers – Suitable for bigger leisure trailers up to the 3500kg gross limit common in European towing regulations.
Engineered for Strength & Long Service Life
Built to exacting Knott OEM standards, every Knott trailer torsion axle in this chassis undergoes rigorous quality checks before despatch. The torsion rubber-in-shear suspension elements self-dampen road shocks without the wear-prone shackles and springs of conventional setups, while the 250×40 brake drum geometry offers a larger friction surface and better heat dissipation during repeated downhill braking. For Russian and European operators who count on trailers to earn their living, this 3500KG tandem chassis represents years of reliable, low-maintenance service.
