A refrigerated semi-trailer is used to transport all kinds of goods that need to be refrigerated. Due to its large body, low transportation loss and tiny problem of obesity, it has gradually become the main force of medium and long distance cold chain transport, with strong market demand. It is possible to make money to transport goods by refrigerated semi-trailer. When selecting refrigerated semi-trailer, it is necessary to comprehensively consider the chassis of the trailer, the insulation box body and the refrigeration unit to select the appropriate refrigerated semi-trailer. Let's learn how to choose refrigerated semi trailer together with Custom semi trailer manufacturers.
What is the refrigerated semi trailer?
refrigerated semi-trailer is a kind of refrigerated truck, which is mainly used in the cold chain transportation industry, such as the transportation of fruits and vegetables, pork, seafood, milk and other items with elevated preservation temperature.
The refrigerated semi-trailer is composed of a trailer chassis, insulation box body, refrigeration device and accessories. According to different user needs, ventilation device, refrigeration device, shelf, suspension device, goods fixing device and so on can be installed in the car.
Two, refrigerated semi trailer to make money
Refrigerated semi-trailers are used to transport goods that need to be kept cold and fresh. In recent years, with the increasing popularity of cold chain transportation, the demand for refrigerated semi-trailers is also increasing, which is mainly reflected in the following aspects:
1, the national logistics of goods quality requirements are higher and higher, fresh food must use refrigerated trucks.
2, the national current regulations, for the problem of overweight, semi-trailer than other refrigerated cars can better avoid.
3, refrigerated semi trailer can achieve fresh fruits and vegetables transport nearly "zero" loss, transport fuel saving rate is greater than 20%, goods temperature difference ±1°, considerably reduce transport loss, improve transport efficiency.
4. The body of a semi-trailer refrigerated truck is typically relatively tall, the length can reach 13.5 meters or 15 meters, which can load additional goods, save fuel costs, and contribute to improving the comprehensive economic benefits of road transportation.
In the medium and long distance cold chain transportation, refrigerated semi-trailer has always been the main force. Under the strong market demand, it is still possible to make money to transport goods by refrigerated semi-trailer.
Three, refrigerated semi trailer on how to choose
refrigerated semi-trailer is one of the most critical equipment in the process of cold chain transportation. When selecting, it can normally start from the chassis of the trailer, the insulation box body and the refrigeration unit:
1. Chassis selection
Normally, it is necessary to consider the type and quality of the goods transported and the volume of the insulated cargo box to determine the tonnage of the chassis. At the same time, the bearing capacity, fuel consumption and emission standards of the chassis should be considered. In addition, because the goods transported by refrigerated semi-trailer are generally not long-term preservation, although equipped with refrigeration equipment, but still need to be quickly sent to the destination, if there is a fault on the road, it is easy to lead to the deterioration of the transport goods, huge losses, so we should focus on the reliability of the chassis.
2. Body selection
The box body of the refrigerated semi-trailer needs to ensure excellent sealing and heat insulation performance. When selecting the box body, attention should be paid to the water absorption, air permeability, thermal conductivity and corrosion resistance of the box body material. And the body is required to have excellent temperature stability, not because of temperature changes and affect other performance.
In addition, different types of goods have different requirements on the car body. For example, the refrigerated semi-trailer transporting fresh meat needs to customize hooks in the car body. For commercial and super distribution, one needs to use a multi - temperature layer refrigerated truck.
3, refrigeration unit selection
The refrigeration unit is divided into independent unit and nonindependent unit. The independent unit has a separate power source; the non-independent unit is driven by the motivation of the chassis of the car, which can be considerably cheaper than the independent unit. The choice is mainly based on the transportation demand: short distance distribution between urban or district and county, it is recommended to use the non-independent unit, and the price is inexpensive; medium and long distance transport, it is recommended to choose an independent unit.
