1、載重大。目前攪拌車(chē)運輸車(chē)攪拌車(chē)筒容量一般為8~12m3，但也有很多大方量的攪拌車(chē)車(chē)攪拌車(chē)筒容積可達到14~16m3，按照每立方混凝土拌合料的密度為2400kg/m3來(lái)計，10m3的攪拌車(chē)車(chē)總重就可以達到35噸左右，更大方量的攪拌車(chē)車(chē)其質(zhì)量更大，這樣一來(lái)攪拌車(chē)車(chē)的質(zhì)量太大，在制動(dòng)時(shí)慣性力非常大，制動(dòng)距離勢必要增加很多；

1. Heavy load. At present, the capacity of Mixer Truck Drum of mixer truck transporter is generally 8~12m3, but there are also many generous mixer trucks. The volume of mixer truck drum can reach 14~16m3. Based on the density of 2400kg/m3 per cubic meter of concrete mixture, the total weight of 10m3 mixer truck can reach about 35 tons. The mass of more generous mixer truck is larger, so the mass of mixer truck is too large, and the inertia force is very large when braking, The braking distance must be increased a lot;

2、攪拌車(chē)車(chē)質(zhì)心高。路面上的攪拌車(chē)車(chē)，車(chē)身高度基本上在3.85米以上，車(chē)身高使得攪拌車(chē)車(chē)的整車(chē)質(zhì)心比較高，在行駛中極易發(fā)生側翻事故；

2. The mass center of the mixer truck is high. The height of the mixer truck on the road is basically more than 3.85 meters. The height of the truck makes the mass center of the whole mixer truck relatively high, which is very prone to rollover accidents during driving;

3、視線(xiàn)盲區大。攪拌車(chē)車(chē)的駕駛室比較高，其車(chē)前保險杠以下、右側車(chē)門(mén)下方和車(chē)尾全為視線(xiàn)盲區，如行人或非機動(dòng)車(chē)行駛在該盲區時(shí)，攪拌車(chē)車(chē)轉彎時(shí)很容易發(fā)生刮擦事故；

3. The blind area of vision is large. The cab of the mixer truck is relatively high, and there is a blind area under the front bumper, under the right door and at the rear of the truck. For example, when pedestrians or non motor vehicles are driving in this blind area, the mixer truck is prone to scratch accidents when turning;

4、產(chǎn)生偏向力。攪拌車(chē)車(chē)在運輸途中攪拌車(chē)筒要時(shí)刻保持旋轉，導致其質(zhì)心向轉動(dòng)方向偏移一定距離，造成攪拌車(chē)車(chē)左右側車(chē)輪載荷不同，從而產(chǎn)生偏向力。

4. Generate deflection force. During transportation, the mixer truck drum should keep rotating at all times, causing its centroid to shift a certain distance to the rotation direction, resulting in different wheel loads on the left and right sides of the mixer truck, resulting in bias force.

此外駕駛員方面也是造成小型混凝土攪拌車(chē)危險交通事故發(fā)生的一大原因，駕駛員意識淡薄是造成交通事故多發(fā)的主要原因。有些攪拌車(chē)車(chē)司機，因交通法制觀(guān)念淡薄，意識差，忽視交通，導致事故發(fā)生；經(jīng)濟利益驅使。攪拌車(chē)車(chē)司機的工資通常是底薪加提成，提成是按出車(chē)次數算的，因此司機為多掙錢(qián)而疲勞駕駛、超速、甚闖信號燈。

In addition, drivers are also a major reason for the occurrence of dangerous traffic accidents of small concrete mixers. The main reason for the frequent occurrence of traffic accidents is the lack of safety awareness of drivers. Some cement mixer truck drivers, due to the weak concept of traffic law and poor safety awareness, ignore traffic safety, resulting in accidents; Driven by economic interests. The salary of the mixer truck driver is usually the base salary plus commission, which is calculated according to the number of trips. Therefore, the driver is tired of driving, speeding, and even breaking the signal light in order to earn more money.
