Container Transport 5‑Axle Flatbed Semi Trailer

Product Introduction

ZW Group’s 5‑Axle Flatbed Semi Trailer and Container Transport Flatbed Semi Trailer are engineered for heavy‑load, intermodal freight transport. Designed to haul containers (20 ft / 40 ft / 45 ft / 53 ft), machinery, steel pipes, and oversized cargo, these trailers deliver industry‑leading payload performance, durability, and cost‑efficiency.

Key Features & Advantages

• Universal Strength & Coating

Constructed from high‑strength Q345B or HG60 steel beams and side frames, fully welded with advanced automated welding, the trailer frame resists torsion and bending.  The painting process includes one coat of anticorrosive primer and two coats of final paint to ensure corrosion resistance and exterior durability

• Axles & Tires

Standard axle brands: FUWA or BPW, rated ~13 t/axle.  Tires: 12R22.5 or 11.00R20 vacuum/triangular heavy‑duty tires from FUWA or equivalent.  Rims: 9.0 × 22.5 steel rims.  The followed specs deliver excellent stability, rolling resistance, and longevity

• Suspension & Ride Stability

Mechanical multi‑leaf springs (10–13 layers) sized 90 × 13 mm or 90 × 16 mm provide rugged reliability.  Optional air suspension upgrades offer smoother rides, adjustable load leveling, and reduced fatigue during heavy long‑haul operations

• Braking & Lighting

Equipped with a standard 24 V pneumatic air‑brake system, optional ABS available.  Lighting assemblies include LED/reliable tail lights, brake, turn signals, side lamps, and reflectors for enhanced safety and compliance

• ISO Container Compatibility

Fitted with 12 ISO twist locks distributed evenly, the trailer supports one 40 ft container or two 20 ft containers, for fast, secure locking.  Interface flexibility caters to 20 ft, 40 ft, 45 ft, or 53 ft units

• Customization / Configurability

Options include axle count (2/3/4/5), wheelbase configurations (e.g. 7 180/6 680/6 260 + 1310 + 1310 mm), suspension type, color, branding/logo, packaging method, optional air‑suspension and ABS system, custom dimensions per customer requirements

Production Process

• Raw‑material selection: Q345B/HG60 high‑tensile structural steel beams and plates

• Beam cutting & forming: CNC high‑precision plasma cutting, forming of main girder and side beams

• Welding: Robot‑assisted full automatic welding (frame, cross‑members, brackets)

• Assembly: Suspension, axles, twist locks, kingpin, landing legs fitment by certified technicians

• Painting: Pretreatment → anti‑corrosive primer → final coat(s) in customer color

• Quality inspection: Structural integrity, weld inspection, dimension check, painting finish

• Static load test & finishing touches

Load‑Capacity Testing

• Static load test: individual trailer undergoes structure load validation up to 110 % of rated payload.

• Dynamic/road test simulation: vertical fatigue and bending tests on load-bearing beams and suspension.

• Brake system validation: air brake pressure, response time, leak test, optional ABS functional test.

• Container twist lock tests: locking/unlocking force and engagement repeated cycles to check reliability.

Shipping & Packaging

• Packaging: delivered as naked export unit (bulk), or loaded into 40HQ / 45HQ container (two trailers per 45HQ with minor disassembly), or Ro‑Ro deck shipping.

• Protection: critical points (bearing, electronics, paint edges) are wax‑ or film‑wrapped; chassis frame lightly coated in anti‑rust oil.

• Documentation package: includes user manual, spare parts list, certification (ISO 9001, CE, DOT, CCC, GCC), inspection report, and drawings.
