Product Overview

zw group 4 axles flatbed semi trailer built from high-strength steel, the chassis employs laser-cut precision and robotic welding to create uniform seams and deep penetration welds that resist fatigue under repeated heavy loads.  Multi-layer surface treatment—sandblasting, epoxy primer, and premium top coats—provides long-term protection against corrosion, particularly important in coastal or salt-exposed routes.4 axle container flatbed semi trailer is a robust and versatile piece of equipment essential to the global supply chain. Designed to efficiently transport various cargo types, including containers, this trailer offers a unique    combination of capacity, stability, and maneuverability.

Specification

Load Capacity and Stability

Rated between 80 and 100 tonnes depending on configuration and local regulations, the trailer’s 4-axle layout distributes weight evenly to maximize road stability while reducing per-axle stress. The mechanical suspension system is engineered for heavy loads, with thickened manganese steel leaf springs that absorb impact and reduce shock transfer to both cargo and tractor. For operators who require refined ride characteristics on smoother highways, an air suspension variant is available as a factory option.

Compatibility with Containerized and Oversized Cargo

The trailer accommodates standard 20 ft, 40 ft, and 45 ft ISO containers using configurable twist-lock sets—4, 8, or 12—providing secure and compliant fastening for container transport. Beyond containers, the open deck supports oversized items such as construction machinery, steel plates, and pipe bundles. Adjustable ride height and robust landing gear (JOST) simplify loading from docks and mobile cranes.

Tires, Traction and Rolling Efficiency

Equipped with 16 wear-resistant radial tires (standard 12R22.5), the trailer gains improved traction and lower rolling resistance—resulting in better fuel economy and extended tire life. Customers may specify alternate tire sizes and brands to suit regional availability and road conditions.

Safety and Braking

Prioritizing driver and cargo safety, the trailer integrates the WABCO brake system, delivering responsive electronic control and proven reliability under heavy payloads. Additional safety features include reinforced side guards, reflective markings, and optional sensor packages for load monitoring. All units undergo comprehensive braking and road-simulation tests during final inspection to ensure dependable stopping performance in real-world conditions.

Customization and Configuration Options

Recognizing that logistics requirements vary, we offer a broad range of customization options: adjustable deck lengths and widths, 2/3/4 axle setups, choice of axle brands, tire sizes (11R22.5, 12R22.5, or customer-specified), mechanical or air suspension, twist-lock arrangements, and additional accessory packages. Our engineering team can adapt the trailer for specialized cargo securing, integrated winches, or reinforced decks for concentrated loads.

Operational Benefits and Target Users

This trailer is specifically designed for fleet operators, port terminals, heavy-haul contractors, and logistics providers who require a versatile platform capable of moving both containerized and oversized goods. Key operational benefits include:

• High payload capability with even axle load distribution for regulatory compliance.

• Easy adaptation between container and non-container moves, improving utilization rates.

• Durable finish and corrosion protection reduce lifetime maintenance and repaint cycles.

• Proven components (BPW axles, JOST landing gear, WABCO brakes) simplify global parts sourcing and service support.

Typical Use Cases

1. Intermodal container transfers at ports and rail terminals, using twist-locks for secure handling.

2. Transporting heavy construction machinery and components across highways and industrial sites.

3. Handling long or oversized steel products, pipes, and prefabricated structures.

4. Bulk logistics operations requiring a rugged, low-maintenance platform for repeated heavy cycles

Delivery and Shipping

Typical lead time is 20–30 working days after deposit, subject to production scheduling. Export options include containerized shipment, bulk vessel, or RO-RO, depending on destination and buyer preference. Each trailer is prepared for sea carriage with corrosion-protective measures and secured according to international shipping standards.

Frequently Asked Questions

Q: What is the trailer's maximum load?

A: The standard configuration is rated for 80–100 tonnes of payload; actual capacity depends on the final specification and local road regulations.

Q: Can it carry both 20ft and 40ft containers?

A: Yes. With configurable twist-lock sets (4, 8, or 12), the deck secures standard 20 ft, 40 ft and 45 ft ISO containers safely.

Q: Are customization and alternative suspensions available?

A: Yes. Options include air suspension, alternate axle brands, different tire sizes, and bespoke deck configurations to match operational needs.
