The explosion of the chemical tank truck in Wenling, Zhejiang on June 13 caused heavy casualties, and the safety of hazardous chemicals transportation has once again attracted the attention of government departments and practitioners of hazardous chemicals. In fact, in order to improve the safety of the transportation of hazardous chemicals, manufacturers have also used more and more new technologies in vehicle equipment in the past two years to ensure the safety of drivers.
Intelligent Auxiliary System Standard Equipped
According to the previously issued "GB7258-2017", the relevant requirements for the safety of the braking system, the protection of the vehicle and the prevention of emergencies are made, such as the transportation of hazardous chemicals, the disc brakes, and the automatic adjustment of the brake gap , EBS (electric brake system), fuel tank is less than 400L, etc.
In addition, in the new "JT/T 1285" it is also proposed to install tire pressure monitoring for dangerous goods tractors and dangerous goods transport vehicles with a total mass of approximately 12 tons; dangerous goods transport vehicles with a total mass of approximately 12 tons It should be equipped with EBS; dangerous goods transport vehicles should be equipped with lane departure warning and front collision warning.
In view of the above regulatory requirements, it can be seen that manufacturers have introduced intelligent auxiliary systems in the past two years to help improve the safety of vehicles. For example, at the 2019 Shanghai Auto Show, SAIC Hongyan exhibited a car-tank integrated dangerous chemical vehicle equipped with ADAS advanced auxiliary driving system, anti-fatigue driving warning system developed based on face recognition technology, ESP body stabilization system, AEBS Emergency braking system, 360-degree look around, tire pressure monitoring, steering explosion-proof tires, hydraulic retarder.
These intelligent assistant systems can each play their own unique advantages in the driving process, and guarantee safe driving in multiple directions. For example, the 360-degree surround view camera is convenient for checking the visual blind areas at the front of the cab and the left and right sides; the AEBS emergency braking system is embedded inside the bumper pedal, which can alert you when there is a danger during driving in an emergency. And trigger active braking in emergency situations to avoid or reduce driving accidents; ACC adaptive cruise function can make the vehicle keep a safe distance from the vehicle in front and avoid collision.
In addition to SAIC Hongyan, the hazardous chemical vehicles manufactured by FAW Jiefang, Foton Auman, Sinotruk SITRAK, XCMG, etc. are also equipped with the above-mentioned intelligent auxiliary system to ensure the safety of driving under the relevant regulations.
Automatic Transmission + Hydraulic Retarder
In addition to improving the safety of vehicles through the use of intelligent auxiliary systems, automatic transmission has more and more applications in commercial vehicles, and there are also signs of developing automatic transmission in the field of hazardous chemicals. For example, the power chain of Hongyan's car tank integrated intelligent hazardous vehicle uses the combination of the Philippine Cursor11+ZF12 gear AMT gearbox, equipped with Iveco patented in-cylinder brake technology, as well as hydraulic retarder blessing.
Compared with manual gearboxes, automatic gearboxes have more prominent advantages in reducing fuel consumption, alleviating driving fatigue, and coping with harsh road conditions. Reduce manual intervention during driving. When running at high speeds, you no longer need to use the left hand to step on the clutch like the previous manual gear, and the right hand is holding the shift lever. You can focus more on unexpected situations. Therefore, the application of automatic transmission on hazardous chemical vehicles is still very necessary.
In addition, the integrated design of truck tanks with more safety protection is also more and more popular with manufacturers, which will also become a trend of hazardous chemical vehicles.
Integrated Truck Mounted Tank
The integrated tank design of the tractor and trailer, which has the advantages of high matching, reduced wind resistance, high safety, etc., can improve the consistency and convenience of the use of the entire vehicle; technical standards, data communication have been fully unified, and can achieve the tractor , Trailer coordinated control, thereby improving the vehicle's driving stability and safety.

Backward Cab Technology
The rearward movement of the cab technology is a passive safety technology that moves backward when subjected to a frontal collision, effectively cushioning the impact of a frontal collision and reducing damage to the driver.
For example, in a previous case, a friend of a driver in Inner Mongolia drove a heavy-duty truck to rear-end at Badaling Expressway. The entire vehicle was severely damaged, but the two drivers in the cab were safe and went straight out of the car; a HOWO T7H was on Yunnan Expressway On the rear-end vehicle, the heavily deformed cab retreated two meters, allowing him to successfully save his life, all of which benefited from the technology of backward cab. But it has to be said that because the technology of cab rearward movement will move backwards a whole distance after a collision, not all dangerous goods vehicles are suitable for this technology.
According to GB7258-2017, all newly produced hazardous chemicals vehicles must be equipped with an air suspension device as standard from January 1, 2020. Compared with the traditional steel plate suspension, the air suspension has the advantages of light weight and good stability. This is very necessary for the flammable and explosive liquids or gases loaded on most hazardous chemical vehicles. The goods are driven during transportation The more stable, the higher the safety of the cargo.
Disc Brake System
According to the requirements, from January 1, 2019, the semi-trailer for the transportation of dangerous goods must be equipped with disc brakes. Because the disc brakes cannot be drenched in water, many card friends still have some doubts about its safety. However, according to the current situation on the market, the thermal attenuation of the disc brake is much smaller than that of the drum brake. In addition, the heat dissipation speed of the disc brake itself is faster than that of the drum brake, so it can meet the braking requirements during continuous braking.
In addition, the disc brakes have extremely high requirements for the safe operation of the driver during driving. It is best to use it with a hydraulic retarder or in-cylinder brake to exert its advantages.
Wireless Connecting Truck Technology
With the application of Internet of Vehicles technology, it can realize positioning, navigation, fleet management, remote diagnosis, and a number of safety assistance for vehicles to prevent the loss of vehicle and cargo.
For example, SAIC Hongyan's intelligent hazardous chemicals monitoring platform can monitor cargo, driving, and equipment in all directions, and monitor the running status of hazardous chemicals main vehicles and tank valves in real time. When an abnormality occurs, it can be tracked and tracked through a map Functions such as playback and intelligent video capture fault information, effectively preventing risks.
Due to the particularity and high risk of the transportation of hazardous chemicals, it has always been the focus of national attention. The improvement of vehicle technology has also provided further protection for the life safety of drivers. Not only do hazardous chemical transport vehicles need these safety technologies to escort, but ordinary cargo transportation also needs, because the damage to the driver is irreversible once the accident occurs.
