Inventory in the domestic "soil and water" trailer models

From the perspective of the development of the global logistics industry, Europe's logistics system is relatively developed, logistics transport tools and supporting equipment technology is more advanced, especially the trailer, its technology is almost the world's leading, such as lightweight, standardization, specialization, etc., are worthy of domestic reference content, some people even say, The development of Europe's trailer industry today will be the development of China's trailer industry tomorrow.

However, there are such a part of the model, in Europe is very popular, the popularity is relatively high, but introduced into the country, but everywhere is restricted, or regulations and policies, or national conditions, or road conditions, working conditions, etc., the advantages can not be played, and gradually declined over time.

Today, with the DARO trailer axle, take stock of those trailer models that are not suitable for domestic soil.

1. Long head car

Long-head semi-trailer refers to the tractor with a "long nose" model. Owners who know the history of truck manufacturing in China may know that in the early days of the founding of New China, the trucks produced in China were long-headed. Later, around 1983, China began to manufacture flat-head trucks, GB1589-1989 promulgated, the total length of the semi-trailer is not more than 17 meters, of which the carriage accounted for 13 meters, leaving the maximum tractor is only 4 meters, so only the engine moved to the bottom of the cab, the long-head truck gradually declined.

To say that the advantages of the long head semi-trailer are also many, such as the cab with a buffer zone of about 2 meters, higher safety; The engine is moved to the front of the cab for better driving comfort, and it is also easy to open the hood during maintenance; When the vehicle is driving, the long-head design can also reduce air resistance, and save fuel and efficiency to a certain extent.

However, there are disadvantages, such as its "long nose", although it can enhance the buffer, it affects the driving vision, the turning radius is longer, and the turning or U-turn is not flexible, especially in the domestic terrain is complex, and the driving is more difficult. In addition, the length of the tractor is longer, and the weight of the vehicle is heavier, which is also a disadvantageous condition under the constraint of the total weight limit.

2. Full trailer

For many old drivers, full trailer is not unfamiliar, after all, in the 1980s and 1990s, the scope of full trailer application is still relatively wide, is a strong flexibility, high load rate, low manufacturing costs of the model.

However, with the popularity of China's expressways, the defects of full trailer operation difficulty, poor driving stability, unstable braking distance, and insufficient transport capacity have gradually been exposed. Since the regulations in 1995 made it clear that the full tractor should not enter the highway, the full trailer began to gradually replace the semi-trailer, retiring to the port, port, transfer station and other transportation conditions.

The new national standard GB1589 added a middle axle trailer, many owners feel that the middle axle and the full trailer seem to be very similar in appearance, thinking that it is concerned about the car changed a name, in fact, this is not the case, the middle axle trailer and the full trailer whether in the axle position, traction device, or composition structure, connection position, there are many differences.

3. Side curtain car

Side curtain trailer is the main logistics means of transport in European countries, its loading and unloading efficiency is high, can achieve left, right, after, on the flexible loading and unloading of goods, the application range is very wide. Some netizens even joked: there are only two kinds of trailers in Europe, side curtain and non-side curtain.

Because of its unique advantages, it was also introduced by the domestic trailer factory a few years ago, but in actual use, it was found that it was not suitable for domestic use conditions.

One is the greater dependence on the pallet, which is not suitable for casual placement of less-load, general merchandise or green goods; The second is that the goods are not fixed, the support is poor, if the shaking or tilting occurs during transportation, or the road conditions of curved slope and steep slope, the speed must not be too fast, otherwise it is easy to throw the goods out of the carriage; In addition, the anti-theft performance of side curtain semi-trailer is not as good as other models, and the purchase cost is high and the maintenance is difficult.

However, since the introduction and implementation of GB7258-2017, the warehouse grid trailer has ushered in more stringent technical requirements, and many of them have begun to look for alternative models, and the side curtain trailer has become the preferred object. Some industry insiders said that the side curtain trailer or will become a hot product in the semi-trailer field.

4. Semi-hanging mixing truck

Semi-trailer mixer is also very common in Europe, the main reason is that Europe for the number of axles and load restrictions are more strict, semi-trailer mixer compared to the traditional vehicle weight, so it has been widely used.

However, in China, the volume of most of the four or eight stirring bicycles can basically reach more than 10 square meters, and even can reach about 15 square meters, which is basically equivalent to the volume of European semi-trailer stirring trucks.

The most important thing is that most of the mixing trucks need to access the narrow, bad road site, if the flexibility is not strong, turning or reversing will be more difficult, and some parts of the urban area will be restricted or banned for the semi-trailer, to a certain extent, limiting the use of the semi-trailer.

5. Three-way flip dump truck

Under normal circumstances, the most widely used dump truck in China is mainly backflip or side flip, and the three-way flip dump truck in Europe can support left flip, right flip and back flip, and the unloading is more flexible and convenient.

Correspondingly, the cargo compartment support foot needs to support multi-direction flipping at the same time, its fixity and stability will correspondingly become worse, the failure rate will be greatly increased, the domestic dump truck working conditions are more complex, and the overload phenomenon is frequent, not suitable for the fragile cargo compartment support foot.

In addition, multi-direction unloading has higher requirements for the site, which must be large enough, wide enough and flat enough, so as to give full play to the advantages of the dump truck, and its loaded goods also have certain limitations.
