Dump Trailers by Chieftain Trailers

Chieftain's dump trailer range covers capacities from 12 tonnes (SB12) to 25 tonnes (SB25 and HP25). The SB series is available in 12, 14, 16, 18, 20, and 25 tonne models. The HP series, featuring Hardox 450 bodies as standard, comes in 16, 18, 20, and 25 tonne variants. Fast Tow versions are available for higher road speeds.

In practical terms, dump trailer and tipping trailer refer to the same type of trailer. Both tip their load by raising the body hydraulically. In the UK and Ireland, "dump trailer" is the more common term for agricultural models, while "tipping trailer" is often used for commercial and road-going versions. Chieftain manufacture both agricultural and commercial tipping trailers.

Hardox 450 is a high-strength abrasion-resistant steel made by SSAB. It offers significantly better dent and wear resistance than standard mild steel, meaning the trailer body lasts longer when handling abrasive materials such as gravel, stone, and root crops. Chieftain's HP series dump trailers feature Hardox 450 bodies as standard.

Yes. Chieftain's Fast Tow variants (SB16FT, SB18FT, SB20FT, SB25FT) are equipped with commercial axles, parabolic spring suspension, and air and hydraulic brakes. These are designed for safe towing behind high-speed tractors at speeds up to 40kph on public roads. Standard SB models are also road-legal but intended for lower-speed agricultural use.

Chieftain dump trailers are available with hydraulic brakes (standard SB series) or load-sensing air brakes (HP series and Fast Tow variants). Load-sensing air brakes automatically adjust braking force based on the trailer's weight, providing safer stopping when loaded or empty. The HP series uses WABCO EBS electronic braking for precise control.

A standard dump trailer has a rectangular body suited to general farm materials, loose bulk loads, and mixed use. The half-pipe design, available in Chieftain's Hardox Half Pipe range, uses a curved trough-shaped body that resists material sticking, making it better for wet or cohesive loads such as quarry aggregates, sand, and tarmacadam. The choice depends on the primary material being transported.

Every Chieftain dump trailer is shot-blasted to remove mill scale and contaminants before receiving a two-pack primer and paint finish. This process provides long-lasting corrosion resistance under heavy agricultural use. The HP series adds Hardox 450 steel as an additional defence against wear and abrasion on the body panels.
