Box Cargo Drawbar Full Trailer
The Box Cargo Drawbar Full Trailer is a high-security, weather-tight commercial freight trailer engineered for express logistics, dry van cargo transport, consumer goods, and high-value intermodal delivery. Built with high-strength Q345B/Q550 structural steel and continuous automated submerged-arc welding, it features a fully enclosed body constructed from heavy-duty corrugated steel, aluminum panels, or lightweight composite insulated sandwich boards. Designed as a self-supporting full trailer with an independent front steering bogie, it incorporates a 360-degree ball-bearing slewing ring turntable and a heavy-duty triangular drawbar towing mechanism, placing zero vertical hitch load on the towing truck. Equipped with 13T–16T commercial axles, heavy-duty mechanical leaf spring or air suspension, dual-line ABS/EBS air braking, and multi-door lock assemblies, it provides superior security, high volume capacity, and smooth highway tracking for regional and cross-border road transport.
