4 axle lowbed semi trailer

In the freight transportation sector, the 4-axle lowbed semi-trailer, with its superior performance and powerful practicality, has become a reliable assistant for many transportation companies and individual transporters.

Strong Load Capacity

The four-axle design gives this low-bed semi-trailer excellent load capacity. The 4-axle lowbed semi-trailer can easily handle the transportation needs of various heavy goods, whether it's large machinery, steel structures, or engineering vehicles, ensuring safe and stable transport. The reasonable axle load distribution makes the vehicle more stable during driving, effectively reducing pressure on the road surface and improving transportation safety.

Low-Flatbed Design Advantages

The low-bed structure allows for a lower loading height and a more stable center of gravity. This not only increases stability during transportation and reduces the risk of cargo swaying and tipping, but also facilitates the loading and unloading of large and extra-wide cargo. The lower platform height allows for easier loading and unloading using forklifts, cranes, and other equipment, greatly improving loading and unloading efficiency and saving time and labor costs.

Superior Materials and Craftsmanship

This vehicle is constructed using high-strength steel, ensuring the robustness and durability of the vehicle body. Advanced welding processes and sophisticated manufacturing techniques ensure tight connections between all vehicle components, resulting in excellent fatigue resistance and impact resistance. After rigorous quality testing and adjustments, each 4-axle lowbed semi-trailer meets the demands of high-intensity, long-duration transport operations.

Flexible Handling Performance


Equipped with an advanced suspension and steering system, the vehicle offers excellent handling during operation. Whether driving at high speeds on highways or turning and making U-turns on narrow roads, it handles situations with ease. Simultaneously, the vehicle's reliable and responsive braking system enables rapid stopping in emergency situations, ensuring safety during transport.

01

The entire structure of the Tianjun semi-trailer is designed using advanced PRO/ENGINEER three-dimensional modeling, finite element analysis, and frame mechanics analysis. This ensures structural rationality while optimizing the compatibility of all components. As a result, the vehicle achieves uniform load distribution, reduces spring and tire wear, and enhances overall safety.

02

Raw materials for the Tianjun series semi-trailer are sourced from reputable brands, utilizing high-quality steel. Our objective is to ensure superior quality and capacity while minimizing curb weight to maximize profitability for our customers. We have established a robust sourcing system to guarantee this high standard.

03

The lightweight high-strength steel semi-trailer features innovative side beams that not only widen the bottom section but also incorporate an edge fold of 20mm. This design significantly enhances vehicle strength and effectively increases its load-bearing capacity while ensuring resistance to distortion.

04

The beam employs an H-style steel flange straightening machine that effectively mitigates issues related to flame correction and welding stress in H-beams. This manufacturing process guarantees beam integrity and prevents bending deflection in the flange plate.

05

The main beam and through beam form a space frame structure. The main beam utilizes high-quality tensile steel combined with automatic submerged arc welding techniques; it undergoes shot peening treatment as well. These processes collectively balance strength, stiffness, toughness, enhance loading capacity, and provide permanent deformation resistance.

06

Our stamping rigid suspension consists of tandem leaf springs paired with hanging supports. This thoughtful design ensures strong rigidity and load-bearing capability while reducing impact forces. Balanced axle loads along with optimized lever angles minimize frictional sliding distances effectively lowering tire wear.

07

Under the premise of ensuring intensity, we have reduced partial weight, incorporated new accessories, and optimized loading capacity while minimizing curb weight.

08

The double circuit brake system, featuring renowned brand relay valves and high-quality ABS, enhances the safety of vehicle operation and extends tire lifespan. 

09

The latest LED energy-saving lamps offer superior brightness, excellent visibility in foggy conditions, stable performance, and an extended service life.


This low bed semi trailer is equiped with 4 axles and and can be used to transport about 40 tons of heavy machinery or construction materials. Whether it is a large excavator, bulldozer, or other heavy equipment, this trailer can complete the transportation efficiently and safely.
