How many tons of cargo can trailer air suspension hold?

Lightweight is the mainstream trend in the current automotive industry, and freight vehicles are no exception. Driven by this trend, the application frequency of airbag trailer axles is becoming higher and higher, from tractor to semi-trailer, it can be seen.

Compared with the steel axle, the air bag axle is light in both material and weight, leading many owners to question whether it can afford the weight of the goods.

In fact, such doubts are unnecessary. After all, the airbag axle is not an emerging product, before putting into the market has carried out countless tests on its frontal load tonnage, and then put into the market, and many foreign countries and regions of heavy duty trucks are the choice of airbag axle, the installation ratio reached more than 80%, which also explains the reliability of the airbag axle to a certain extent.

However, this "reliable" is a prerequisite, one of which is that it cannot be overloaded, otherwise once the use of the airbag axle is exceeded, the probability of damage or scrap in advance will be far more than the steel plate axle, and the maintenance cost is much higher.

In addition, the use of the airbag axle should also strictly control the air pressure of the airbag, away from exposure and acid, alkali, oil, organic lubricants and other environments, careful use of sand and stone splashing and other road conditions, daily vehicle parking and maintenance should also pay attention to many matters.

In addition, the original intention of the airbag axle was not to improve the load, on the contrary, it is to control the overload phenomenon. Take the domestic mandatory three-axis fence plate, warehouse grid semi-mounted airbag axle, one of the reasons is that these vehicles have high ownership, can be poor safety technology, transport of goods are mostly low value-added products, so many owners are in accordance with the nuclear load limit or even beyond the load limit for transport, affecting traffic safety, will also increase the damage to the road. Forcing the use of airbag axles can reduce overload to a certain extent and improve the safety factor.

Of course, the advantages of the airbag axle itself are also an important reason for its wide promotion, excellent shock absorption, light weight, protection of goods, free lifting, but also reduce tire losses, protect chassis parts.

As for how many tons can be pulled by the airbag axle, that is, how much is the load-bearing limit of the airbag axle, it is necessary to analyze the specific problems, and consider the size, material, thickness, configuration, and use environment of the airbag axle.

Under normal circumstances, the airbag axle sold by the trailer axle factory will clearly mark the carrying capacity, such as 11t, 13t, 15t, etc., as long as it does not exceed this range, basically there will be no problem.

In addition, if it is to match the factory airbag axle with the model, it is necessary to look at the load limit of the model, for example, the load limit of the three-axle plate semi-trailer is 49t, then subtract the vehicle's own weight, the remaining is the safe weight that the car can bear, as long as the use of proper methods, or more durable.

Since it comes to the issue of durability, by the way, the service life of a set of airbag axles is generally about 3-5 years, and basically needs to be replaced in this range. If the owner uses a particularly fine, daily maintenance is better, it can be used for about 5 years, if the use condition is bad, or it is not used according to the instructions, the service life of the airbag axle will be greatly reduced.

In any case, if you want to ensure the safety and service life of the airbag axle, you must choose products with all parameters at the beginning. DARO's airbag axle series, using the European design, long airbag travel, long service life, rated load of 13t, can effectively reduce cargo loss, improve operational efficiency.
