This trailer is designed to provide exceptional strength and stability under extreme loads (typically 80-160 tons). The main beam structure is constructed from high-strength steel alloys such as 16Mn or Q345B, typically employing an I-beam or reinforced box-type structure design to resist bending and torsional loads under heavy loads. The four-axle configuration ensures excellent weight distribution and complies with road axle load regulations, with each axle typically carrying 13-20 tons.
The suspension system can be configured with heavy-duty mechanical leaf springs, or optionally equipped with air suspension to improve ride smoothness and load stability. Standard configuration uses high-quality axles from leading brands such as FUWA, SAF, or BPW. The braking system employs dual-circuit air brakes, with ABS optional for enhanced safety. A rear-mounted hydraulic or mechanically assisted folding ladder facilitates easy loading and unloading for both tracked and wheeled vehicles.
We offer comprehensive customization services, from axle selection and chassis design to accessory configuration, to ensure that this 4-axle low-flatbed semi-trailer becomes a reliable and essential piece of equipment for your heavy haul transportation business.
