Tri Axle 20 FT Platform Trailer For Sale

Tri Axle 20 FT Platform Trailer Manufacturer

Tri axle 20 FT platform trailer detail

The tri axle 20 ft platform trailer is a straightforward, high-capacity hauler for logistics operations, construction equipment moves, and oversized cargo runs. Its flat, open deck design accepts containers, steel coils, machinery, and bundled materials without the loading restrictions of enclosed trailers. HUAYU builds this platform trailer with a 70-ton rated capacity on three axles, giving operators enough margin for heavy construction loads while keeping tare weight controlled. For oversized heavy equipment, see our low bed trailers.

A simple structure does not mean a weak one. The main beams run the full 12,500mm length, and the 2,500mm width fits standard road regulations in most markets. At 1,600mm overall height, the deck sits low enough to keep total vehicle height manageable even with tall cargo stacked on top.

Tri Axle 20 FT Platform Trailer Suspension Detail

Tri axle 20 FT platform trailer suspension

The suspension system is the core component controlling how a semi-trailer handles load, road shock, and directional stability. Regular maintenance keeps these components performing at their best. HUAYU mechanical suspension on this platform trailer is reinforced at different rates from front to back and left to right, which distributes stress more evenly across the frame during loaded operation. The two suspension connecting rods are reinforced with round tubes and channel steels, and angle steels brace the front, rear, and both inner and outer sides. That layered reinforcement means the suspension arms resist twisting forces on rough roads rather than transferring them directly into the frame welds.

Platform Trailer Floor Design

The floor of this tri axle platform trailer uses a 3mm thick patterned bottom plate. The raised pattern increases surface friction, which prevents cargo from sliding during braking or turning. It also reduces direct wear on the deck surface because contact pressure distributes across the pattern ridges rather than concentrating on flat steel. For operators hauling steel plate or machinery with metal tracks, that friction advantage means less reliance on additional dunnage or tie-down points.
