Core Technology

  • Welding: Using automated submerged arc welding equipment, continuous welding is applied to the frame, beams, and flatbed joints. The welds are strong and well-formed, reducing structural deformation even under long-term heavy loads, significantly extending service life and adapting to frequent transport scenarios.
  • Painting: The trailer body is sandblasted first, then coated with multiple layers of anti-rust primer and wear-resistant topcoat. The coating has strong adhesion and excellent scratch resistance, corrosion resistance, and UV resistance, effectively protecting against rain and construction dust, keeping long-term rust resistance, and reducing maintenance costs.

Main Features

  • Main Beam: Made of Q345 or T700 high-strength steel, strong load capacity, stable and reliable structure, not easily bent or deformed under long-term heavy loads, providing solid support for cargo transportation.
  • Patterned Steel Floor: Anti-slip patterned steel plate design increases friction with cargo, effectively preventing sliding during transport.
  • Open Deck Design: The open design without barriers allows cranes, forklifts, and other equipment to load/unload cargo from multiple angles, suitable for goods of various shapes and sizes.
  • Twist Locks and Stakes: Fixing methods include container twist locks or removable stakes, providing secure fastening for containers or goods to ensure transport safety.
  • Brake System: Equipped with WABCO air brake system with ABS, reducing braking distance and improving driving stability.
  • Suspension: Customizable with mechanical suspension or air suspension. Mechanical suspension is simple and durable, more economical; air suspension provides better shock absorption, protecting precision equipment or fragile cargo.
