Introduction: As a semi-trailer factory, the lowbed trailers we manufacture have a payload capacity ranging from 30 to 150 tons, which can meet the transportation needs of most heavy machinery and construction equipment. Lowbed trailers are mainly used for heavy-duty transport, which requires high-quality steel and advanced manufacturing processes. Therefore, customers should choose a well-known semi-trailer manufacturer for customization.
The lowbed trailers produced by Vehicle Master offer a load capacity of 30–150 tons. According to customer load requirements, we use heavy-duty axles, reinforced beams, and high-strength steel while optimizing the chassis structure to meet heavy transportation demands. We also provide optional configurations such as detachable goosenecks, loading ramps, and width extension components.
Our lowbed trailers feature a high-low(Lowbed) and high-low-high(Lowboy) structural design, which lowers the center of gravity, improves stability, and thus enhances safe load-bearing capacity.
Two Main Lowbed Trailer Structures
1. Lowbed Structure (Gooseneck Lowbed Trailer)
Classic step-style design with a lower main platform
Lower platform height for easier loading
Good stability and strong load capacity
Suitable for most types of construction machinery
2. Lowboy Structure (Detachable Gooseneck)
Ultra-low middle platform with higher front and rear sections
Lower center of gravity, suitable for extremely heavy cargo
More even weight distribution and better road performance
Ideal for transporting oversized, tall, or concentrated heavy loads
Payload Capacity by Axle Configuration
| Trailer Type | Axles | Typical Payload | Typical Application |
| Light Duty Low Loader | 2 axles | 20–40 tons | Small machinery, vans, buses |
Standard Low Bed | 3 axles | 50–70 tons | Excavators, bulldozers, loaders |
Heavy Duty Low Bed | 4 axles | 70–100 tons | Large cranes, mining equipment |
Extra Heavy Duty | 5+ axles | 100–150 tons | Oversized modules, industrial machines |
Key Factors Affecting Load Capacity
Axles
We configure axles based on trailer length and target load capacity. Our axles include 13 tons, 16 tons and 20 tons heavy‑duty models.
We use our own brand axles as well as famous branded axles such as FUWA and BPW, to ensure strong and reliable load capacity.
Chassis Material
Our low bed trailers use high‑strength steel for main frame and platform. The material has high tensile strength, stable structure, no deformation under heavy load, and greatly improves overall load capacity and service life.
Suspension Type
We provide multiple suspension options for customers to choose and customize: Mechanical/ Air/ Hydraulic suspension. Different suspensions adapt to different road conditions and load requirements.
Loading Method
Hydraulic detachable gooseneck: mainly used for High‑Low‑High low bed trailers, convenient for large equipment to load
Heavy‑duty ladder: mainly used for High‑Low low bed trailers, suitable for self‑propelled machinery such as excavators
*Both designs achieve fast, safe and convenient loading.
Other Configurations
Widening components / Tire‑exposed or non‑tire‑exposed design / extra lashing points, etc.
Why Our Low Bed Trailers Have Excellent Load Capacity
Professional high‑low and high‑low‑high structures lower the center of gravity and improve stability
High‑strength steel chassis for heavy loads without deformation
Optional 13T/16T/20T axles from reliable brands
Flexible suspension and loading customization
Strict production and welding quality control
Factory direct supply with stable and reliable quality
Conclusion
Low bed trailers are versatile heavy‑duty transport equipment. Standard 3‑axle models carry 50–70 tons, 4‑axle models carry 70–100 tons, and customized multi‑axle models can reach 100–150 tons. When choosing, please select the appropriate axle, structure and configuration according to the maximum cargo weight, and comply with local transportation regulations to ensure safe and efficient transportation.
