There are many ways to distinguish between heavy and light trucks, the most obvious of which is to look at the dead weight of the vehicle. Light ** often refers to the total mass of the design in 18 to 4Trucks between 5 tons, while heavy trucks refer to trucks with a total mass of more than 14 tons.
As for the amount of cargo carried, it is not an absolute indicator. Some heavy trucks do not carry much cargo, while others can carry a large amount of cargo.
Generally speaking, light trucks are suitable for short-distance, intra-city, and small cargo transportation, while heavy trucks are more suitable for long-distance, highway and large-scale cargo transportation.
Light trucks have the advantage of being flexible, convenient and economical, while heavy trucks are characterized by their carrying capacity, stability and efficiency.
In addition to this, there are mini trucks, that is, the total mass is less than 18-ton small trucks;
Medium-duty trucks: trucks with a total mass between 6 and 14 tons;
Light ** often uses blue plates, while medium-sized trucks basically use yellow plates.
Generally speaking, most heavy trucks have more horsepower, cabin height and length than light trucks. As a result, the cargo capacity of light trucks is usually lower than that of heavy trucks, but it is not absolute.
There are also some heavy-duty trucks with strong carrying capacity in light trucks, and their carrying capacity is not even inferior to that of heavy trucks.
Therefore, when choosing a pulling tool, it needs to be considered according to the characteristics of the goods being transported.
In addition, long-distance transportation can be achieved by rail or airplane, but urban distribution is difficult to be replaced by other methods, so all kinds of light trucks have become the main bearers of urban transportation.
From the perspective of development trends, new energy light trucks have become an inevitable choice for urban transportation.
However, at the user level, in addition to the core pain points such as "poor returns, low efficiency, and poor environmental awareness", people have also begun to pay attention to new issues such as "mileage, safety, and transportation efficiency" for new energy light trucks.
However, although it is a trend, pure electric heavy trucks still face many challenges in large-scale promotion.
Although the battery-swapping heavy truck solves the problem of slow charging speed of ordinary electric heavy trucks and is expected to become an alternative to ordinary electric heavy trucks, the construction of battery swap stations still faces many difficulties, including complex approval processes, difficulties in site selection and distribution access, and difficulties in sharing and intelligent promotion of battery swapping.
The approval standards for the construction of battery swap stations are also inconsistent, and coordination is difficult, and many cities do not clarify whether battery swap stations can enjoy subsidies for the construction of new energy vehicle charging infrastructure, which further widens the gap between the construction and operating costs of charging stations.
In addition, the current battery standards are not yet unified, and the construction of separate infrastructure is also a problem.
Due to the fact that many enterprises use different power battery manufacturers, specifications, shapes and sizes, they cannot be universal, and enterprises can only build their own battery swap stations, which brings many restrictions in terms of infrastructure.
However, in this regard, it is believed that there will be improvements in the future.
