BRIEF

The 4 Axles 50T Low-bed Trailer with Hydraulic Ramp is engineered for heavy-duty transport, built with a high-strength steel frame and a rugged dual main beam structure that delivers exceptional load capacity and torsional resistance. Its 4-axle configuration with paired tires ensures optimal weight distribution, supporting a payload of up to 50 tons – making it the ideal choice for moving heavy machinery and oversized cargo.

Designed for real-world efficiency, the trailer features L1 brand steering axles and a liftable axle system. The steering axles enhance maneuverability, reduce tire wear, and lower rolling resistance – directly translating into fuel savings. The liftable axle can be raised when the trailer is empty or lightly loaded to minimize tire wear and rolling resistance, then lowered under full load to maximize weight distribution. This intelligent system reduces unnecessary tire consumption, lowers fuel costs on return trips, and minimizes maintenance expenses.

Loading and unloading are made simple with a rear hydraulic ramp, providing safe and convenient access for heavy equipment. Built for durability, reliability, and operational economy, the low-bed trailer delivers a dependable solution for transporting heavy equipment, construction machinery, and oversized loads across any job site.

FEATURES

1. Double Main Beam Frame – Built for 50-Ton Heavy Loads

The trailer features 430 mm deep double main beams with reinforced flanges and webs for exceptional structural strength. Designed to carry payloads of up to 50 tons, it minimizes frame flex, improves stability, and reduces long-term fatigue, making it ideal for demanding construction and mining applications.

---

2. Steering Axle – Easier Maneuvering

The 13-ton steering axle follows the tractor during turns, improving maneuverability on narrow roads and confined job sites. It reduces tire scrub, minimizes steering effort, and helps drivers complete tight turns with greater confidence.

---

3. Liftable Axle – Lower Fuel and Tire Costs

The 13-ton liftable axle can be raised when the trailer is empty or lightly loaded to reduce rolling resistance, tire wear, and fuel consumption. When fully loaded, it lowers automatically to distribute weight evenly across all axles.

---

4. Automatic Slack Adjusters – Less Maintenance

Automatic slack adjusters continuously compensate for brake wear, keeping the braking system correctly adjusted without frequent manual maintenance. This improves braking performance, reduces workshop time, and enhances operational safety.

---

5. Leaf Spring & Air Suspension – Strength Meets Comfort

The combination of leaf springs and air suspension delivers excellent load capacity and ride comfort. Leaf springs handle heavy loads, while air suspension absorbs road shocks, protecting both the trailer and transported equipment.

---

6. Hydraulic Rear Ramp – Faster Loading

The hydraulic rear ramp allows heavy equipment to be loaded quickly and safely without additional lifting equipment. It reduces loading time, improves job-site efficiency, and enables one-person operation.

---

7. Electrophoretic Coating – Long-Term Corrosion Protection

The chassis is sandblasted and finished with an electrophoretic coating for outstanding corrosion resistance. Tested to 500+ hours of salt spray, it helps protect the trailer in coastal, wet, and harsh working environments.

---

8. ABS + EBS Braking System – Safer Heavy Transport

Equipped with ABS, EBS, dual-chamber brake actuators, and a tri-axle synchronizing valve, the trailer delivers stable, responsive braking, improving control and reducing the risk of wheel lock during emergency stops.

---

9. Factory-Installed Kingpin – Reliable Connection

A factory-installed heavy-duty kingpin provides a secure connection between the tractor and trailer. Built for demanding transport applications, it ensures long-term reliability and dependable towing performance.

---

10. Heavy-Duty Hardwood Deck – Built to Last

The 5 mm thick hardwood deck is designed to withstand repeated loading of tracked and wheeled machinery. Its durable construction resists wear and impact, extending service life while reducing maintenance costs.
