Products Advantages
Ultra-low cargo platform, suitable for extremely heavy loads
The loading platform of a regular truck is approximately 1.2 - 1.5 meters above the ground, while the flatbed area of a swivel-low flatbed truck is only 0.8 - 1.2 meters above the ground (some customized models are even lower). The maximum height it can carry goods can reach 3.3 - 3.7 meters. There is no need to dismantle large equipment (such as transformers, wind power components, and tall construction machinery) for compliant transportation, avoiding the time loss and equipment damage caused by disassembly and reassembly.

Strong load-bearing capacity, suitable for overweight goods
The body is made by welding high-strength steel and is often equipped with multi-axis (6-axis, 8-axis or even more) designs (the number of axes is directly proportional to the load-bearing capacity). The rated load capacity is generally above 30 tons, and some customized models can exceed 200 tons. It can stably carry heavy goods such as excavators, bulldozers, large machine tools, and prefabricated bridge beams, meeting the heavy transportation needs in the fields of engineering and industry.

The "curved neck" structure enhances safety and space utilization.
The towing part is bent and arched upwards in a "goose-neck" shape. On one hand, it creates a gap between the towing vehicle cab and the cargo platform, preventing the extremely long goods (such as wind turbine blades, long pipe equipment) from colliding with the cab. On the other hand, it makes the center of gravity of the goods closer to the ground, reducing the risk of overturning during transportation (especially during turns and bumpy sections), and at the same time distributing the pressure of the goods on the vehicle body, extending the service life of the vehicle.

Easy loading and unloading, reducing auxiliary costs
Most vehicle models are equipped with hydraulic or mechanical folding rear ramps. Large equipment (such as crawler excavators and wheeled loaders) can directly drive onto the cargo platform using their own power, without relying on external auxiliary equipment like cranes or forklifts. The loading and unloading process does not require complex operations, significantly reducing the loading and unloading time, and at the same time reducing the cost of leasing auxiliary equipment.

High versatility, supporting customized modifications
The basic model can meet the needs of most regular large-scale cargo transportation. At the same time, it can be customized according to the specific characteristics of the goods: such as installing detachable guardrails (to prevent goods from sliding), adding fixed anchor points (for binding irregular goods), extending the flatbed (suitable for ultra-long goods such as wind turbine blades), installing hydraulic steering shafts (to enhance the flexibility of turning on narrow roads), and adapting to special transportation scenarios in various fields such as engineering, energy, industry, and military.
