新しい100Ton Lowbed Semi Trailer 低床セミトレーラ

HUAYU 4 axles 100 ton lowbed semi trailer with low center of gravity for transporting heavy vehicles, mining machinery, and construction equipment.
HUAYU builds the 4 axles 100 ton lowbed semi trailer with quality and long service life as the primary design goals. The company selects Q345B steel — the highest grade in common use for semi-trailer frames — which directly extends the trailer's working life across the rough road conditions that African and Asian operators face daily.
Q345B Steel for Long Service Life
HUAYU uses Q345B steel for this 4 axles lowbed semi trailer because the 345 MPa yield strength resists deformation under heavy, repeated loading cycles. For customers running on unpaved mine roads, potholed highways, and dusty construction routes, that resistance to deformation means the main beams and side beams hold their shape over years of use rather than developing the permanent bows and cracks that weaker steel frames show after one or two seasons.
HUAYU products meet strict customer transportation requirements by matching the steel thickness of girders and side beams to the rated load capacity. Every trailer ships with beam dimensions that support the weight it was built to carry.
Advantages of the 4 Axles Lowbed Semi Trailer
High-Strength Materials and Construction
The main beam uses high-strength steel such as HG high-strength steel and "H" section steel profiles. This construction method prevents side beam deformation under heavy load, which is the most common structural failure point on lowbed trailers. The loading ramp is also built from high-strength steel, so it holds its shape even when heavy tracked equipment drives across it repeatedly.
Low Frame Cargo Platform
The main plane of the frame cargo platform sits low to the ground. That low deck position keeps the center of gravity down during transport, improving stability and road safety. It is the reason this lowbed semi trailer handles large machinery and steel cargo with less sway during turns and braking than taller trailer designs.
Three-Axis Balanced Suspension
The suspension system runs on three-axis balanced, two-axis balanced, or rigid configurations. A mass balance block sits between the front and rear leaf springs to keep the deflection change equal across all axle positions. Equal deflection means equal load sharing — no single axle carries more than its rated share, which prevents premature tire and bearing wear.
Broad Application Range
This 4 axles lowbed semi trailer handles mechanical equipment, large oversized objects, highway construction machinery, large tanks, power plant equipment, and steel of various types. The load capacity reaches 100-120 tons, which covers the weight range of most heavy construction and mining machines in common use.
Durable Finish
Polyurethane paint protects the frame and deck from corrosion. In tropical and coastal operating environments where humidity and salt exposure accelerate rust, polyurethane coating holds up better than standard enamel paints and extends the time between repainting cycles.
100-120 Ton Load Capacity
The 4-axis configuration spreads the rated 100-120 ton load across enough axles and tires to keep ground pressure manageable on public road networks. For operators who need to move the heaviest construction machines on road-legal trailers, this load rating covers the majority of equipment in the field today.
