Why is it difficult to popularize soft curtain trailers in China?

To say that the current general trend of the freight industry is lightweight. Lightweight can not only increase loading capacity and improve transportation efficiency, but also reduce fuel consumption, improve energy saving and emission reduction, which coincides with the road of "cost reduction and efficiency increase" insisted by my country's logistics industry. Under such a trend, various light-weight models and parts have entered the market, and the soft curtain car is one of them.

As for the soft curtain car, it is a common logistics transportation tool in European countries. It is said that more than 80% of the bicycles and trailers in Europe use the soft curtain structure.

The soft curtain trailer looks similar to the box trailer in appearance, but the materials used on the sides and top of the cargo compartment are different.

Generally speaking, guide rails are installed on the top of the cargo compartment of a soft-curtain trailer, and the lower side is a locking structure. Soft tarpaulins are used on both sides of the cargo compartment. When loading and unloading goods, the soft curtain can be easily pushed and pulled to any position; the top of the cargo compartment can also use a soft cover. The interior is equipped with supporting rails, which can completely store the tarpaulin at one end of the cargo compartment, which is convenient for loading and unloading from the top of the cargo compartment; as for the tail of the cargo compartment, it is generally a traditional double-door structure, and the material is mostly light steel or aluminum alloy. , can dock with the goods platform of the logistics company like an ordinary semi-trailer.

In order to ensure the stability of the goods during transportation, a mobile stabilizing pile can be installed on the inside of the soft curtain, just like the railing of the warehouse truck. This kind of stabilizing pile can move back and forth, which is convenient for loading and unloading; The structure is fixed, and then more cross bars can be built on it, usually made of aluminum alloy or wood.

In this way, the advantages of the soft curtain car are very obvious:

While maintaining the closedness of the cargo compartment, the convenience of cargo loading and unloading is taken into account. The weight of soft tarpaulin, aluminum alloy, wood and other structures is also lighter than that of traditional vans. According to industry insiders, soft curtain trailers with the same size and model can reduce the weight by more than 3t compared with steel trailers.

For a long time, we have been with Europe in terms of vehicle technology. Domestic R&D design, regulations and standards are almost carried out with reference to Europe. Many models currently used in my country are replicas of Europe. Logically speaking, soft curtain cars should also be popular in China, but the fact is that soft curtain cars have not been able to be popularized on a large scale since they entered the domestic market. I am afraid that this will start from the limitations of the soft curtain car:

1. The cost is extremely high.

Soft curtain vehicles generally need to be equipped with airbag bridges, aluminum alloy railings, aluminum rings, hollow frame, etc. The super high cost prolongs the payback cycle to a certain extent. In the current transportation environment with small profit margins, many car owners Can only stay away from it.

2. There are risks in transportation safety.

If the vehicle shakes or tilts during transportation, the curtain with particularly good quality can also support the weight of the goods. If the curtain is of poor quality, the goods may be thrown out of the compartment, seriously affecting traffic safety.

3. The application scenarios are limited.

This is the most important factor restricting the popularization of soft curtain cars. The soft curtain car is indeed convenient for loading and unloading, but that is for palletized transportation and mechanical loading and unloading. At present, most logistics parks and consignors in my country do not have the conditions for palletized transportation, let alone retail investors who are fighting guerrillas across the country. owner.

4. Inconvenient maintenance.

Compared with traditional steel materials, tarpaulins for soft curtain vehicles have obvious disadvantages in terms of damage prevention. In addition, there are more various parts on soft curtain vehicles, such as tracks, waterproof glue, locking structures, fasteners, etc. , all require custom maintenance.

5. Poor anti-theft performance.

Especially when the car owner is resting during transportation, such as in the service area, it is more common to steal oil and goods. In this regard, the soft curtain is not as strong as the cargo box made of steel, and it does not have an advantage in anti-theft performance. Therefore, many Cars with soft curtains are not dared to be used for the transportation of valuable goods.

At present, domestic soft curtain trailers are mainly used in some short-barge cargo transportation with relatively high popularity of pallets, and a large number of retail car owners still prefer to choose traditional trailers. Therefore, soft curtain cars are not widely popular, to a certain extent, because they do not conform to China's national conditions. As for whether the soft curtain vehicle will usher in the peak of development and popularization after the logistics industry becomes more and more standardized, I am afraid that it depends on how much its "acclimatization" problem can be improved.

Lightweight transportation In addition to changing the model, choosing a lighter suspension and trailer axle is also a reliable way. As a representative of lightweight products, DARO disc airbag bridge has advanced structure, unique technology, and more compact design. It is equipped with integrated high-strength alloy materials and square shafts with larger section coefficients. It is lighter in weight, more load-bearing, and can be handled calmly Isotropic stress, better shock absorption performance.
