The 40FT Fence Semi Trailer is a semi-trailer specially designed for efficient cargo transportation, with a solid and durable overall structure. The vehicle body dimensions are 12,400mm in length and 2,500mm in width. It is equipped with a fence design of 1,800mm that can be flexibly divided into sections (600mm+100mm+400mm+100mm+400mm), which can not only meet the loading requirements of goods of different sizes, but also improve the loading and unloading efficiency by adjusting the height of the fence It is especially suitable for transporting bulk cargo, agricultural products or goods that require lateral fixation.
The main beam of this model is made of Q345B high-strength steel, featuring a 500mm high “H” shaped structure. Combined with a thickened design of 14mm top plate, 8mm web plate, and 16mm bottom plate, it ensures excellent bending resistance under a rated load of 40,000kg. Supplemented by 16# channel steel side beams, 10# channel steel crossbeams, and 3mm thick patterned steel plate platforms, a multi-support system is formed, effectively dispersed with the impact force during transportation.
This model achieves a balance between a self-weight of 8,000kg and a total weight of 48,000kg through lightweight design, maximizing the utilization rate of cargo space within the compliance range. The suspension system adopts a standard mechanical suspension with 10 13mm×90mm leaf springs, paired with 3 13-ton Mingyue brand axles and 12 Linglong 12R22.5 tires, forming a stable load-bearing structure. Combined with a dual-pipeline pneumatic braking system, 40L dual air tanks, and Wabco emergency relay valves, it ensures rapid and reliable braking response.
In terms of detailed design, the 28-ton two-speed manual outriggers, 24V electrical system, 7-pin standard sockets, and other configurations meet the basic operation requirements. Meanwhile, the SA2.5 grade shot blasting treatment and the application of anti-rust primer + topcoat with a thickness of no less than 80μm enhance the vehicle’s corrosion resistance in complex environments.
