4 axles lowbed semi trailer

4 axles lowbed semi trailer is a transport equipment that performs well in the field of heavy cargo transportation.

1. Structural design

Axle layout

The vehicle adopts a 4-axle design. This multi-axle layout can reasonably distribute the weight of the cargo. When loading heavy cargo, each axle is subjected to appropriate pressure, which effectively prevents damage to the road surface due to excessive local pressure, and also ensures the stability and safety of the vehicle.

Low-bed design

The low-bed structure is its important feature. The low height of the low-bed reduces the center of gravity of the cargo, greatly reducing the risk of cargo tipping or vehicle rollover during transportation. This is very beneficial for transporting super-high, super-large and high-center-of-gravity heavy equipment, such as large wind turbine blades and heavy construction machinery.

2. Performance advantages

Carrying capacity

It has a strong carrying capacity and can transport cargo weighing tens or even hundreds of tons. It uses high-strength steel to manufacture the frame and body structure, which can withstand huge pressure and tension, ensuring that there will be no deformation or damage when transporting heavy cargo.

Applicability

Applicable to a variety of different road conditions. Whether it is a flat highway or a rugged construction site road, the 4 axles lowbed semi trailer can adapt well. Its sturdy suspension system and tires can buffer road bumps and protect the cargo from vibration.

3. Transportation efficiency

Easy loading and unloading

The low-bed design makes loading and unloading of goods more convenient and quick. A variety of loading and unloading methods can be adopted, such as crane lifting, forklift handling, etc., which reduces the time of loading and unloading goods and improves the overall transportation efficiency.

Flexible combination

It can be flexibly matched with various tractor heads, and the appropriate tractor head can be selected according to different transportation tasks and transportation distances, so as to achieve the best transportation combination and improve transportation economy.

With its unique structural design, excellent performance advantages and high transportation efficiency, the 4 axles lowbed semi trailer has become an indispensable and important equipment in the field of heavy cargo transportation.


4-Axle Lowbed Semi Trailer


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.
