1.1 right front corner accident
由於攪拌車運輸產品所決定，駕駛室較寬較高，行車中或起步時如不刻意觀察，將發生右前角與人員或車輛碰撞的事故，是攪拌車發生事故頻率最高的部位，存在著事故風險。
Due to the product transportation of the mixer, the cab is wide and high. If you don't observe carefully during driving or starting, the right front corner will collide with people or vehicles, which is the most frequent part of the mixer, and there is an accident risk.
1.2 右轉彎事故
1.2 right turn accident
混凝土運輸車輛在轉彎時都存在著內輪差，當右轉時駕駛員稍有分心或左側有情況需要觀察時，由於攪拌車右側反光鏡的視角較窄，當車輛移動中駕駛員通過反光鏡看到行人或車輛時再采取製動措施，車輛雖然停住但事故可能已經發生。即移動車輛至發生事故時間快於駕駛員采取措施預防事故所需時間，如果駕駛員未觀察或未觀察到，那發生事故將成為必然。
When turning right, the driver is slightly distracted or the left side needs to observe. Due to the narrow angle of view of the right mirror of the mixer, when the driver sees the pedestrian or vehicle through the mirror, he takes braking measures. Although the vehicle stops, the accident may have occurred. That is to say, the time from moving the vehicle to the accident is faster than the time for the driver to take measures to prevent the accident. If the driver does not observe or observe, the accident will become inevitable.
1.3 翻車事故
1.3 rollover accident
翻車事故通常有以下幾種情形如：裝載混凝土後攪拌車中心提高，轉彎時未有效控製車速，在離心力的作用下，攪拌車失去控製（穩定性）而發生向外翻車事故。再有是公路由於各種原因導致路麵不實，表麵外觀良好，但其下方因沉澱而造成空虛，當重載攪拌車通過時，路麵無法承受其重量，導致翻車。還有是攪拌車進入工地，因工地施工環境複雜，如臨時鋪墊的道路，借用先前的土路，使用後的泥漿池回填等各種原因，導致通行路麵鬆軟，不能承受重載攪拌車，而此時攪拌車通過將可能導致翻車。當雨後土路經反複碾壓後，造成車輛兩側輪胎下的路麵高低懸殊過大，當重載的攪拌車通過時因側偏導致重心失穩而造成翻車事故。
Rollover accidents usually have the following situations, such as: after loading concrete, the center of the mixer increases, the speed of the mixer is not effectively controlled when turning, and under the action of centrifugal force, the mixer loses control (stability) and rollover accidents occur. Moreover, the road surface is not solid due to various reasons, and the appearance is good, but the bottom is empty due to precipitation. When the heavy-duty mixer passes through, the road can not bear its weight, leading to rollover. In addition, due to the complex construction environment, such as the temporary paved road, borrowing the previous soil road, and backfilling the mud pool after use, the road surface is soft and can not bear the heavy-duty mixer. At this time, the mixer may overturn. When the earth road is repeatedly rolled after the rain, the road height under the tires on both sides of the vehicle is too large. When the heavy-duty mixer passes, the center of gravity is unstable due to the side deviation, resulting in the rollover accident.
1.4 路口事故
1.4 traffic accident
攪拌車重載通過路口時，當駕駛員行車中判斷能夠通過路口（特別是綠燈即將結束時）如果不減速，一旦發現意外情況，即使采取製動措施也無法有效控製車輛，可能會導致惡性事故發生。
When the mixer truck passes through the intersection with heavy load, if the driver judges that he can pass through the intersection (especially when the green light is about to end), if he does not slow down, once an accident is found, even if braking measures are taken, the vehicle can not be effectively controlled, which may lead to malignant accidents.
1.5 超速風險
1.5 overspeed risk
重載攪拌車如果超速行駛，一旦遇有意外情況，任何措施對預防事故都將失效，隻能承擔事故後果。
If the heavy-duty mixer is speeding, any measures to prevent accidents will be invalid in case of accidents, and it can only bear the consequences of the accident.
1.6 倒車風險
1.6 reversing risk
攪拌車的功能和結構造成了其尾部存在駕駛員觀察盲區，而倒車是其完成工作的必須操作。一旦駕駛員未觀察到車後有人或物且倒車時，發生事故將成為必然。
Because of the function and structure of the mixer, there is a blind area for the driver to observe, and reversing is the necessary operation to complete the work. Once the driver does not observe people or objects behind the car and reversing, the accident will become inevitable.
1.7 超載風險
1.7 overload risk
攪拌車為追求利益最大化，裝載量越來越大，隨著裝載量的增加，攪拌車的安全性能和操作性能將隨之降低。裝載量的增加將直接導致製動距離的增加，如前所述，一旦遇到緊急情況或意外發生將直接導致嚴重後果。
In order to maximize the benefits, the loading capacity of the mixer is increasing. With the increase of the loading capacity, the safety performance and operation performance of the mixer will be reduced. The increase of loading capacity will directly lead to the increase of braking distance. As mentioned above, in case of emergency or accident, it will directly lead to serious consequences.
