What kinds of goods are considered dangerous goods?
Transport of dangerous goods is an indispensable link in the process of economic development. In recent years, with rapid economic development, especially the petrochemical industry occupies more and more proportion, the demand for transportation service is also increasing. Therefore, the transportation of dangerous goods gradually presents prosperous trend in our country.
Dangerous goods trailer is often used in the transportation of dangerous goods. Generally, it is a special vehicle with the top of the cargo box not closed, the exhaust pipe in front and equipped with a fireproof flower device.
In general, there are nine main types of dangerous goods transported:
Explosive substances, gases, flammable liquids, flammable solids, oxidants, organic peroxides, toxic and infectious substances, radioactive substances, corrosive substances, miscellaneous dangerous substances and articles.
In the past, ordinary trailers can also be used to transport dangerous goods, but now the relevant control is more and more strict, vehicles that do not meet the regulations are not allowed to transport dangerous goods, the reason is for safety.
So, what is the difference between dangerous goods trailer and ordinary trailer?
1. Disc brake and ABS system. The front axle of dangerous goods trailer must be equipped with disc brake, and the whole vehicle is equipped with ABS system, which can guarantee the braking performance, and achieve anti-lock function to improve safety.
2. Exhaust pipe. The engine exhaust pipe of dangerous goods trailer should be in front, and exhaust spark extinguisher should be installed at the tail end of the exhaust pipe to cool the motor vehicle exhaust gas.
3. Vehicle speed. The speed of dangerous goods trailer shall not exceed 80 km/h.
4. Emergency cutting device. Usually, the tank car will be installed. It is a kind of safety device installed at the liquid and gas interface of the liquefied petroleum gas or liquefied gas tank car. When the medium leaks, the valve can be closed by itself for emergency leakage.
5. Warning signs. Dangerous goods transport trailers must be painted with safety notices, explosive diamond-shaped labels, danger lights and orange "explosion" for timely identification and discovery by other personnel.
6. Electrostatic rubber drag belt. Dangerous goods trailers need to be installed on the bottom frame of the vehicle with electrostatic rubber dragging belt, which can introduce static electricity into the ground, so that the box is always at zero position, to prevent the generation of electrostatic sparks.
In addition, the dangerous goods transport trailer should also be installed with traffic recorder, cargo compartment ventilation design, ion smoke detector, electrostatic conductive rubber plate, antiexplosion container and so on, which is much higher than the ordinary trailer.
The reason for such strict requirements is safety. Safety is the most important thing in the transport of dangerous goods. Therefore, in the selection of accessories, dangerous goods trailer must also use load-bearing, braking, safety performance of more reliable products. DARO Group is the first enterprise to mass-produce all-in-one axles in Liangshan special vehicle production base. Compared with traditional three-joint axles, the all-in-one axles independently developed by Daro Group have stronger load-bearing capacity and higher flexural and torsional resistance. DARO trailer axle material selection of high strength alloy seamless steel pipe, 15 high standard production processes, fully stimulate the strength, toughness, elongation, fatigue resistance and other comprehensive mechanical properties of raw materials. DARO axle covers disc type, drum type, concave type, low plate, three line six axis and other products, rich types, can fully meet the needs of customers. In terms of price, DARO trailer axle focuses on cost-effective routes, aiming to provide customers with more affordable prices and higher quality axle.
