Cobalt Trailers – Proven Lowbed Trailer Design for Over 30 Years

Cobalt Trailers has been designing and manufacturing premium lowbed trailers for more than 30 years, earning a reputation as one of South Africa’s most respected trailer manufacturers. Known for intelligent design, robust construction, and dependable product support, Cobalt trailers are built to perform in demanding heavy-haul and abnormal transport applications.

​

The Cobalt range is shaped by the ingenuity and design vision of York Zonneveld, whose practical, operator-focused approach has defined the brand for decades. His ability to challenge conventional trailer design has resulted in some of the most widely used and instantly recognisable lowbed trailers on South African roads.

​

Cobalt has led the local lowbed market with industry-defining products such as the C50 sloping deck, rear-loading step deck, iconic Cobalt rollback trailer, 6-car carrier, and Euro-spec extendable trailers. These trailers are engineered to deliver real operational advantages — low loading angles, safer handling, and fast, intuitive operation — rather than unnecessary complexity.

 

Working closely with Specialised Trailers, Cobalt continues to refine and evolve its product offering. This partnership ensures continuity, technical support, and a clear development roadmap that complements modern heavy-haul solutions, including multi-axle and modular transport systems where appropriate.

​

With the exception of axles and suspension, almost all major components — including hydraulics — are manufactured in-house, ensuring consistent build quality and fast parts availability. More than 90% of parts are available immediately or within 24 hours through the Bredell Trailer Parts facility, minimising downtime and keeping fleets operational.

All Cobalt trailers are fitted with Henred axles and Weweler suspension, proven off-the-shelf running gear manufactured in world-class facilities. This ensures reliable performance, predictable maintenance, and nationwide parts availability.

​

Cobalt trailers are built to last — and it has proven time and again that your first Cobalt is rarely your last.
