1.8m/5.91Ft Split Tailgate Semi-Trailer

Product advantage

1. Robust Structural Design for Maximum Durability & Load-Bearing Capacity

• Reinforced Main Beam: The trailer features a fish-belly main beam with a specification of “top 14, bottom 16, vertical 8” (no special-shaped holes), constructed from high-strength steel. This design distributes stress evenly across the chassis, resisting bending, warping, and fatigue even under maximum payloads. The fish-belly shape enhances load-bearing performance while maintaining a lightweight profile, a critical balance for heavy transport.
• High-Strength Side & Cross Beams: The side beams are 5mm high-strength C-channel (14#), while cross beams use 10# straight steel (5.0mm thickness). These components form a rigid framework that supports the cargo bed and prevents deformation under heavy loads. The 3+3+3 layout of longitudinal beams further reinforces the chassis, ensuring uniform load distribution across the entire platform.
• 1.8m High Cargo Bed with Internal Split Tailgate: The 1.8m tall cargo bed, paired with an internal split tailgate, provides a secure enclosure for bulk cargo (e.g., gravel, sand, construction aggregates) while maintaining flexible access. The side baffles (40603.0mm, six sections with three pairs of split gates) and 140mm high top edge beam create a tall, stable cargo hold that prevents spillage during transit, a key advantage for loose or granular materials.

2. Versatile Split Tailgate & Cargo Bed Design for Flexible Loading/Unloading

• Internal Split Tailgate (Full-Seal DO Type): The rear split tailgate is a full-seal design that can be opened from both sides, allowing for quick and controlled discharge of bulk cargo. This is particularly valuable for construction and mining operations, where rapid unloading of aggregates, soil, or mining overburden is essential. The internal placement of the tailgate protects it from damage during transit, extending its service life compared to external tailgate designs.
• Modular Side Baffles: The side baffles are six-section, three-pair split gates integrated with a 140mm high top edge beam. This modular design allows for partial or full opening of the side gates, enabling side loading/unloading of palletized goods, machinery, or oversized cargo. For example, forklifts can access the cargo bed from the sides, reducing reliance on rear-only loading and speeding up operations in tight spaces.
• 1.8m Cargo Height: The 1.8m tall cargo bed provides ample volume for high-volume cargo (e.g., agricultural produce, construction materials) without compromising stability. The high side baffles prevent cargo from shifting or falling during transit, a critical safety feature for long-haul transport on uneven roads.

3. Optimized Chassis & Running Gear for Reliable Performance

• Heavy-Duty Axles & Suspension: The trailer uses LUCKSUN 16-ton axles (without ABS, manual adjust arm) paired with a 10-leaf 1.690 leaf spring suspension system. This setup provides excellent shock absorption and load distribution, ensuring stable handling on rough roads, construction sites, and rural terrain. The leaf spring suspension is durable and easy to maintain, a key advantage for operators in remote areas with limited access to service facilities.
• Reliable Braking System: The braking system features WABCO relay valves and four dual single-chamber air brakes, ensuring consistent and reliable stopping power even under heavy loads. This system meets global safety standards, reducing the risk of accidents and ensuring compliance with transport regulations in key markets such as Africa, the Middle East, and Southeast Asia.
• High-Capacity Tires & Rims: The trailer is fitted with 315/80R22.5 20PR tires (13 units) and LUCKSUN exclusive 18# steel rims (22.5*9). These heavy-duty tires are designed to handle high loads and rough terrain, with a 20PR rating ensuring exceptional durability and puncture resistance. The specialized steel rims provide a secure fit, reducing the risk of tire damage during transit.
• 28T Interlocking Support Legs: The 28-ton interlocking support legs ensure stable parking during loading/unloading, preventing chassis tilting and enhancing safety for operators. This is particularly critical in construction sites and mining zones, where uneven ground can pose a risk to cargo and personnel.

4. Enhanced Safety Features for Cargo & Operator Protection

• Cargo Security: The 1.8m tall side baffles and internal split tailgate create a secure cargo hold that prevents spillage and load shift during transit. The double-wall tighteners and cast iron rope hooks provide secure lashing points for cargo, further reducing the risk of damage or loss.
• High-Visibility Lighting: The trailer is fitted with 6-inch large round split taillights with width indicator lights, ensuring maximum visibility at night and in low-light conditions. This reduces the risk of collisions with other vehicles, especially on rural roads or in areas with limited lighting.
• Stable Handling: The optimized wheelbase and suspension system ensure stable handling during high-speed transport and cornering, reducing the risk of rollover. The 90# welded kingpin and specified turning radii (≥2200mm front / ≤2250mm rear) enhance maneuverability, making the trailer easy to operate in tight spaces such as port terminals and construction sites.
• Protective Accessories: The trailer includes protective nets (left attachment), toolboxes (right attachment), and a spare tire rack with 2 lift jacks and 2 fire extinguisher mounts. These accessories enhance operational safety and convenience, ensuring operators have the tools and equipment needed to handle emergencies and routine maintenance.

5. Operational Efficiency & Cost-Effectiveness

• High Payload Capacity: The robust chassis and lightweight high-strength design allow for a high payload capacity, enabling operators to transport more cargo per trip. This reduces the number of trips required to move large quantities of cargo, cutting fuel costs, labor expenses, and vehicle wear.
• Low Maintenance Costs: The simple, robust design of the trailer means there are fewer moving parts to repair or replace, reducing maintenance costs by up to 25% compared to more complex trailer types (e.g., dump trailers). The leaf spring suspension and heavy-duty axles are durable and easy to maintain, with minimal requirements for lubrication and inspection.
• Long Service Life: The use of high-strength steel and anti-corrosion treatments (electrophoretic coating for standard colors) extends the trailer’s lifespan by up to 30% compared to generic trailers. This reduces the need for frequent replacements, further lowering long-term costs.
• Flexible Customization: LUCKSUN offers flexible customization options for the trailer, including color choices (electrophoretic coating for standard colors, special colors not applicable) and additional accessories. This allows operators to tailor the trailer to their specific needs, ensuring maximum efficiency and compatibility with their operational workflows.

6. Compliance & Adaptability to Global Market Requirements

• Dimensional Compliance: The overall dimensions (125502650H) are calibrated to meet the standard limits for heavy-duty transport in most countries, eliminating the need for costly oversize permits and reducing route delays.
• Safety Compliance: The braking system, lighting, and structural design meet international safety standards (e.g., ISO 3471, GB7258), ensuring compliance with transport regulations in target markets.
• Adaptability to Diverse Terrain: The leaf spring suspension and heavy-duty tires make the trailer adaptable to diverse road conditions, from smooth highways to rough construction sites and rural dirt roads. This versatility makes it a reliable choice for operators in regions with challenging infrastructure.
