Description
Heavy-Duty Lowboy Trailer for Oversized and Heavy Cargo Transport
Product Overview and Industry Applications
This multi-function 4 axle low bed semi trailer focuses on precision engineering and operational safety. All structural components follow strict manufacturing standards, and the overall design ensures stable performance in demanding heavy haul conditions. Therefore, the trailer delivers reliable results across complex transport environments.
Moreover, optimized dimensions and multiple suspension configurations effectively reduce deck height. As a result, oversized and over-height cargo can pass safely through bridges, tunnels, and uneven roads. This advantage significantly expands transport possibilities for professional logistics operators.
In addition, the trailer suits construction projects, mining equipment transfer, and industrial relocation tasks. It also performs well in special cargo and long-distance logistics operations. Therefore, it remains a dependable solution for global heavy transport markets.
Structural Design and Material Advantages
This heavy-duty lowboy trailer maintains reliability under extreme working conditions. Each structural element supports long-term durability and load stability, which improves operational safety. As a result, the trailer performs consistently during continuous heavy-duty use.
The chassis uses high-strength ST52-A steel to enhance overall structural performance. This material offers higher yield strength and stronger impact resistance. Compared with Q345B steel, fatigue resistance improves significantly.
Therefore, the trailer structure resists deformation under heavy and repeated loads. This advantage extends service life while reducing maintenance frequency and operating costs.
Load Capacity and Dimensional Optimization
The maximum load capacity reaches up to 120 tons, supporting ultra-heavy machinery transport. This capacity allows safe movement of oversized industrial equipment. Therefore, operators gain greater flexibility in complex logistics scenarios.
Overall dimensions measure 15500mm × 2500mm × 3330mm, ensuring compliance with standard transport regulations. The standard 2500mm width suits most cargo requirements, while 250mm movable side wideners provide additional flexibility. As a result, both standard and oversized cargo loads fit efficiently.
This dimensional optimization improves fleet utilization and reduces the need for specialized trailers. Consequently, transport efficiency and profitability increase.
Reinforced Beam Structure and Axle Configuration
The main beam height reaches 350mm to enhance bending resistance under heavy loads. Side beams use reinforced 250# I-beam construction, which improves overall chassis rigidity. Therefore, the trailer handles uneven and concentrated loads more effectively.
The trailer supports four axles rated at 12T or 14T each, depending on operational needs. Optional axle brands include SAF, BPW, and KOC, which deliver stable bearing capacity and braking performance. As a result, long-distance heavy transport remains secure and reliable.
This axle configuration meets international heavy haul standards and supports diverse road conditions. Consequently, operators benefit from improved safety and durability.
Tire Design, Suspension Options, and Stability
The trailer uses 235/70R17.5 tires with steel rims to reduce overall deck height. Smaller tire diameters lower the center of gravity, which improves stability during transport. As a result, driving safety increases under heavy load conditions.
Multiple suspension options include air suspension, hydraulic suspension, and bogie suspension. Each option adapts to different road surfaces and load distributions. Therefore, vibration control and driving comfort improve noticeably.
In addition, improved suspension performance protects cargo and structural components. This feature proves valuable on rough or unpaved roads.
Safety Systems and Loading Efficiency
The 24V LED lighting system ensures clear visibility during night and low-light operations. LED lights consume less energy and require minimal maintenance. Therefore, operational efficiency improves over long service periods.
Optional WABCO braking systems and EBS enhance braking precision and response speed. These systems improve control compared with traditional mechanical braking. As a result, overall driving safety increases significantly during heavy transport.
The standard hydraulic ramp simplifies loading and unloading procedures. Compared with spring ramps, operation becomes safer and less labor-intensive. Therefore, the trailer suits frequent machinery and equipment transport tasks.
Core Advantages of the 4 Axle Low Bed Semi Trailer
The ultra-low platform design supports safe transport of over-height cargo. Optimized axle placement improves clearance and stability across complex routes. As a result, transport risks reduce significantly.
Movable side wideners provide flexible width adjustment for different cargo types. The trailer supports both standard and wide cargo transport needs. Therefore, overall operational versatility increases.
Advanced braking options enhance control during long-distance operations. Electronic systems improve response accuracy under heavy loads. As a result, the trailer meets international logistics and safety standards.
