At about 5:30 a.m. on March 5, a semi-trailer truck with Tianjin license plate braked sharply at 54.5 km (Shuiguan Great Wall to Badaling Bridge) of Beijing-Tibet Expressway in Changping Pipeline, Beijing. The cab was overturned and deformed by the full load of Fanggang in the back compartment, resulting in driver Liu Mous waist injury.
According to the truck driver Liu Mou, he drove from south to north to the above-mentioned location. In order to avoid rear-end collision, he stepped on a sudden brake. As a result, tens of tons of square steel loaded in the slot chamber rushed forward under the great inertia, knocked down the front slot railings and then squeezed the cab out of shape. His back waist and front abdomen were pinched on both sides by the rear steel and steering wheel, resulting in injury to the waist, dislocation of the steering wheel, and serious damage to the cab. Fortunately, the vehicles were climbing the hill at a slow speed, not exceeding 30 kilometers per hour, otherwise the consequences would be unthinkable.
According to the person in charge of the expressway brigade of Changping Traffic Detachment, similar accidents occur every year. The loss consequences of this accident are relatively minor. Many trucks loaded with logs, strips of steel or fluid will have similar consequences once emergency braking is adopted. Some even penetrate the cab and endanger small vehicles in front, causing casualties.
Civilian police here reminds truck drivers that when loading similar goods, they must make the necessary binding and fixing of the goods. Dont think that the front baffle with slot can be a great deal of good, because the forward impulse of the goods will form tens or even hundreds of tons according to the speed of the vehicle, and the slot can not be effectively blocked.
At the same time, according to different road conditions to maintain low and medium speed driving, and the front car must maintain at least two times the safe distance under no-load conditions. During driving, we should observe the road ahead and traffic flow at any time, take slow deceleration measures in advance, and do not take emergency braking. Because the inertial impact force of the cargo is proportional to the speed of the vehicle and inversely proportional to the braking action.
The faster the speed, the greater the inertia force, the harder the brake, the greater the reaction force between the goods and the carriage, the more likely it is to cause accidents. In addition, the police warn that there are similar hidden dangers in loading large non-disassemblable goods, large machinery and vehicles. They also need to take precautions in advance according to the above requirements in order to avoid accidents.
