This 3 axle sidewall truck trailer is designed from a flatbed foundation with detachable side walls to deliver maximum operational flexibility for bulk and unitized transport. Built by ZW Trailer in Shandong, the chassis employs automatic longitudinal beam welding with shot peening to enhance fatigue resistance and structural integrity. The fence panels, typically 600–800mm high, are removable so the platform converts quickly to a flatbed for container or oversized cargo handling.

• Robust 3-axle configuration that supports heavy payloads and stable road behavior.

• Detachable side walls for fast conversion between bulk-haul and flatbed duties.

• High-strength main beam (Q345B) with a 500mm section and dedicated plate thickness for superior load distribution.

• Optional mechanical or air suspension to suit regional road conditions and cargo protection needs.

• Quality axle partners (FUWA/BPW) and standardized tire/rim options for easy maintenance and parts sourcing.

Design and Build Quality

The trailer frame is manufactured with precision welding processes: longitudinal beams are welded and shot-peened, and beam-to-stringer joints are fully welded to create a cohesive box structure that resists torsion. Using Q345B for the main beam and Q235 for side channels balances strength with cost-efficiency, delivering long service life under typical heavy-duty logistics operations. Every critical weld is executed to ensure that the trailer can safely sustain the declared ≤60T loading capacity when properly configured.

Materials & Components

Primary materials include Q345B and Q235 steel for structural members, reputable axle options (13T/16T FUWA or BPW), and heavy-duty tires (12.00R22.5 or 315/80R22.5). Rims are provided in common sizes to match regional fleets and service networks. These component choices make it straightforward to maintain uptime and source replacement parts globally.

Operational Advantages

1. Versatility: The removable side walls let operators switch between bulk goods and container-style loads without a second trailer.

2. Payload Efficiency:A 40-foot deck and three robust axles enable high payloads, reducing cost-per-ton transported.

3. Durability:Reinforced beams and thorough welding practices reduce maintenance cycles and improve lifecycle costs.

4. Customization:Side wall height, axle rating, suspension type and tire selections are configurable to match local regulations and application needs
