With the strict control of overloading in various places, some urban highway sand and stone transportation has changed from 4-axle dump truck to semi-trailer dump truck with more axles. The total weight of 49 tons of 6-axle truck is significantly improved than that of 31 tons of 4-axle truck, which can not only legally overload, but also ensure that the transportation volume is not reduced too much.
與自卸車(chē)相同，城市內運營(yíng)的攪拌車(chē)治超也有趨嚴發(fā)展的形式，根據規定，4軸攪拌車(chē)只能安裝攪拌容量8立方米的攪拌筒，對于目前動(dòng)輒18立方米起的4軸攪拌車(chē)來(lái)說(shuō)影響很大。
Similar to dump trucks, the overload control of urban mixer trucks also has the form of stricter development. According to the regulations, the maximum mixing capacity of 4-axis mixer truck can only be installed with mixing drum of 8 m3, which has a great impact on the current 4-axis mixer truck with 18 cubic meters.
基于這樣的背景，一些廠(chǎng)家也推出了混凝土攪拌半掛車(chē)，希望用軸數更多的掛車(chē)來(lái)取代傳統的攪拌車(chē)。
Based on this background, some manufacturers have also launched concrete mixing semi-trailer, hoping to replace the traditional mixing truck with more axles.
但是，理想很美好，現實(shí)很骨感，大部分卡友好像對此并不買(mǎi)單，提出的問(wèn)題也非?，F實(shí)。
However, the ideal is very beautiful, the reality is very skinny, most card friends do not seem to pay for this, and the questions raised are also very realistic.
半掛車(chē)通過(guò)性差
Poor trafficability of semi-trailer
混凝土攪拌半掛車(chē)為掛車(chē)+牽引車(chē)的組合形式，整車(chē)長(cháng)度要比4軸攪拌車(chē)增加許多，現實(shí)生活中的工地并不是每個(gè)都有寬敞的施工空間，過(guò)長(cháng)的車(chē)身靈活性較差，進(jìn)出工地非常不便利。
The concrete mixing semi-trailer is a combination of trailer and tractor. The length of the whole vehicle is much longer than that of the 4-axle mixer truck. In real life, not every construction site has a spacious construction space. The long body flexibility is poor, and it is very inconvenient to get in and out of the construction site.
此外攪拌車(chē)卸料需要與泵車(chē)尾對尾，運輸車(chē)抵達工地之后需要調頭倒車(chē)，半掛車(chē)在調頭和倒車(chē)的時(shí)候操作難度大，不利于精準調整位置，對駕駛員的要求非常高。
In addition, the unloading of the mixer truck needs to be aligned with the tail of the pump truck. After the transport vehicle arrives at the construction site, it is difficult to operate the semi-trailer when turning around and reversing, which is not conducive to accurate adjustment of position, and the requirements for the driver are very high.
由于軸數增加，但是混凝土攪拌半掛車(chē)還是采用6x4驅動(dòng)的牽引車(chē)，只有4個(gè)驅動(dòng)輪，與4軸攪拌車(chē)相同。有駕駛經(jīng)驗的卡友都知道，軸數越多動(dòng)力損耗越大，同樣的路面4軸車(chē)能走過(guò)去，6軸的半掛車(chē)可能就會(huì )陷住。
Due to the increase of the number of axles, the concrete mixing semi-trailer still adopts a 6x4 driven tractor with only four driving wheels, the same as the 4-axle mixer. The more the number of axles, the greater the power loss. If a 4-axle vehicle can walk over the same road surface, a 6-axle semi-trailer may get stuck.
簡(jiǎn)而言之，工地的現實(shí)環(huán)境會(huì )給混凝土半掛車(chē)上一場(chǎng)生動(dòng)的社會(huì )實(shí)踐課。
In short, the actual environment of the construction site will give a vivid social practice lesson to the concrete semi-trailer.
當然也不排除有些工地施工環(huán)境較好，路面鋪裝完備，有足夠大的空間，這種施工環(huán)境使用混凝土攪拌半掛車(chē)沒(méi)有問(wèn)題。
Of course, it is not ruled out that some construction sites have good construction environment, complete pavement and enough space. There is absolutely no problem using concrete mixing semi-trailer in this construction environment.
A2駕駛員人工成本增加
A2 driver labor costs increase
普通的4軸攪拌車(chē)駕駛員只需要持有B2駕駛證即可上崗，工資相比A2來(lái)說(shuō)更低，駕駛員也更為好找。
Ordinary 4-axle mixer drivers only need to hold B2 driving license to work, and the salary is lower than A2, and the driver is easier to find.
混凝土攪拌半掛車(chē)方量更大，為何賣(mài)得并不好？
The volume of concrete mixing semi-trailer is larger, why is it not sold well?
而混凝土攪拌半掛車(chē)由于是牽引車(chē)，必須要有A2駕駛證的駕駛員，不但工資要比B2駕駛員多，擁有A2證的司機也更加難找，如果企業(yè)把普通的攪拌車(chē)換成半掛攪拌車(chē)，駕駛員的緊缺問(wèn)題都夠頭大。
As a tractor, the concrete mixing semi-trailer must have an A2 driver's license. Not only is the salary higher than that of B2 driver, but also the driver with A2 certificate is more difficult to find. If the enterprise changes the ordinary mixer truck to the semi-trailer mixer, the shortage of drivers is big enough.
從運輸成本來(lái)看，混凝土攪拌半掛車(chē)的運載量更大，可以做到14m?左右，比8m?的4軸攪拌車(chē)要多很多，效益增加之后多賺的錢(qián)足夠彌補B2和A2駕駛員的工資成本，但還是無(wú)法A2駕駛員缺乏的問(wèn)題。
From the perspective of transportation cost, the carrying capacity of concrete mixing semi-trailer is larger, which can reach about 14m? Which is much more than that of 8m? 4-axle mixer. After the increase of benefits, the extra money can make up for the wage cost of B2 and A2 drivers, but it still can not solve the problem of lack of A2 drivers.
混凝土攪拌車(chē)告訴大家混凝土攪拌半掛車(chē)方量的特點(diǎn)，大家在購買(mǎi)的過(guò)程中一定要根據自我的需求來(lái)考量！
Concrete mixer tells you the characteristics of the volume of concrete mixing semi-trailer, you must consider according to your own needs in the process of purchasing!
