Revolutionary Single-Beam Frame

The heart of every Bronton trailer is our revolutionary single-beam frame. Unlike traditional, heavier double-beam designs, our technology offers four key benefits: lower weight, higher load capacity, greater strength and rigidity, reliability, and stability.

Advanced Features for Today’s Workloads

ABS as standard – safety is not optional

Bronton is the first in its segment to provide ABS across all trailers. This advanced braking system prevents wheel lock-up, shortens stopping distance, and maintains steering control, setting Bronton apart in critical safety performance.

The Patented Central-Beam Design Sets the GN-L40 Apart

20,000-lb winch & Knuckle Boom Cranes ready construction

Each trailer is equipped as standard with a professional winch with a pulling force of 20,000 pounds, which ensures independence and ease of loading heavy machinery or vehicles from the first day of use. What's more, Bronton thinks ahead – the entire trailer structure is factory-prepared for future installation of a hydraulic knuckle crane, which provides flexibility and the ability to expand its capabilities at any time.

60 cargo securing points & rich LED lighting

Cargo transport safety and road visibility are Bronton's priorities. That is why our semi-trailers are equipped with as many as 30 cargo securing points, which allows for secure and compliant securing of any goods, regardless of their shape or size. In addition, to ensure maximum safety and visibility in all conditions, each semi-trailer is equipped with extensive lighting made with reliable LED technology, guaranteeing excellent visibility of the vehicle on the road.

High-strength steel & Anti-Slip “Cobra” deck

In Bronton trailers, load safety and durability are a priority, which is why we use a floor made of special, wear-resistant steel with increased strength, which is extremely resistant to mechanical damage and deformation. In addition, for maximum traction and load safety, each trailer features a non-slip “Cobra” deck, available in a choice of colors, allowing for personalization and matching to company colors.

Hot-dip galvanizing – protection for years

Our trailers operate in the most difficult conditions – rain, snow, and road salt. That is why we do not compromise on corrosion protection. The entire structure of every Bronton trailer undergoes hot-dip galvanizing. This is the best method available, creating a durable, metallurgical coating that protects steel for decades, even under heavy use.

Suspension options: Pneumatic or Spring

Or do you value maximum simplicity and legendary durability in the toughest terrain, guaranteed by a classic leaf spring suspension? With us, you decide which suspension is best for your job.
