What is an Axle-Line Lowbed Semi-Trailer? An axle-line semi-trailer refers to a trailer configuration where two axles are mounted on a single central axis line—meaning two smaller axles are positioned side by side on one axis. Common lowbed semi-trailers of this type come with 2 to 7 axle lines. Each axle is fitted with 4 tires, so one axle line is equipped with a total of 8 tires. These lowbed semi-trailers typically have a width of over 3.3 meters, making them suitable for transporting oversized cargo. To lower the overall center of gravity of the vehicle, they usually adopt small-diameter steel radial tires with high load-bearing capacity.
Advantages of One Line Two Axles Design
Superior Stability
With two axles placed side by side on a single axis line, the vehicle boasts enhanced stability during operation. Especially when driving at high speeds or making turns, lateral sway is reduced by 30% to 40%, which significantly lowers the risk of rollover and improves overall safety.
High Load-Bearing Capacity
The dual-axle configuration substantially boosts the vehicle’s load-bearing capacity, making it ideal for hauling heavy-duty cargo.
Wide Adaptability
The one line two axles lowbed trailer can adapt to diverse road conditions and transportation requirements, delivering strong practicality.
