With the increase of market governance overloading and the implementation of weight-based charging policies, heavy-duty semi-trailers have gradually been eliminated by the market. However, every industry has a development direction, and for semi-trailers, the current development direction is to develop in the direction of lightweight, which is also what "pull more and run faster" has always pursued. Only by achieving lightweight can the purpose of "pull more" be achieved, and only by achieving "pull more" can the owners achieve improved transportation efficiency and quickly get rich.
Now many semi-trailers choose to overload because the semi-trailer's own carrying capacity is limited, and if it is transported according to the approved cargo volume, the profit will be very small, so many car owners often choose to "take risks" to overload transportation, which will not only increase the incidence of accidents, but also damage the semi-trailer itself. Therefore, in order to better meet the needs of the development of semi-trailers, lightweighting has become an inevitable trend.
We can redesign some components or find alternative materials for lightweight design, which can well reduce the vehicle's own weight. For example, the tires used by semi-trailers are all steel tires, so we can consider using aluminum alloy tires instead, which will significantly reduce the vehicle's own weight. We can also use air suspension systems to replace the current suspension system, which is also a good attempt.
In short, lightweight is now an inevitable development trend of semi-trailers. We should recognize this development trend and then complete the lightweight of semi-trailers through specific design and replacement of related parts. After all, no one wants semi-trailers to drag bulky bodies to transport goods. Only by correctly following the trend of lightweight development can our company develop faster.
