Semi Low Loaders by Chieftain Trailers

A semi low loader is a low-deck trailer pulled by an articulated truck (HGV), used for transporting heavy and oversized loads such as construction plant, industrial equipment, and large machinery. The low deck height reduces overall transport height, allowing taller loads to be carried within legal height limits. Chieftain's semi low loaders hold full EU Type Approval.

Chieftain semi low loaders are available in 2, 3, 4, and 5 axle configurations to suit different payloads. The range includes standard fixed-length models and extendable versions (3 Axle and 4 Axle Extendable) for longer loads. All models are designed and certified for commercial use on public roads across the UK and EU.

Yes. Every Chieftain commercial trailer, including all semi low loaders, has been granted European Whole Vehicle Type Approval by the UK Vehicle Certification Agency. This permits the trailer to be used legally in any EU member state without additional certification. Type Approval covers the trailer's structure, braking, lighting, and suspension systems.

Chieftain semi low loaders are available with hydraulic beavertail ramps, mechanical ramps, and full-width loading ramps. The choice depends on the type of equipment being loaded and the specific application. Hydraulic ramps are standard on most models and are designed to accommodate tracked machinery with low ground clearance.

A fixed-length semi low loader has a set deck length, while an extendable model (such as the Chieftain 3 Axle or 4 Axle Extendable) can be telescoped to a longer deck for oversized loads and retracted for standard transport. Extendable models provide greater versatility but are heavier. The choice depends on the range of loads the trailer will regularly carry.

A semi low loader has a lower deck height than a standard flatbed, which reduces the overall height of the loaded vehicle. This is critical for transporting tall machinery within the 4.95-metre legal height limit. The lower centre of gravity also improves stability. Standard flatbeds are suited to lighter, lower-profile loads where overall height is not a concern.

Yes. Chieftain manufacture both Tri Axle and Quad Axle Deck Widener trailers within the semi low loader range. These specialist models feature decks that widen hydraulically to accommodate oversized loads that exceed standard trailer width. They are Type Approved and designed for transporting wide plant and equipment under abnormal load regulations.
