◆ step 1: check relevant certificates

随车证件关乎到上户，保修等情况

The certificates attached to the car are related to the household, warranty, etc

购车发票

Purchase invoice

要检查购买混凝土搅拌车发票，混凝土搅拌车购车发票非常重要，是重要的购车证明，同时也是混凝土搅拌车上户的凭证，就算到后期混凝土搅拌车当做二手车出售都需要购车发票。

First of all, check the invoice for the purchase of concrete mixer truck. The invoice for the purchase of concrete mixer truck is very important. It is the most important certificate for the purchase of concrete mixer truck. At the same time, it is also the certificate for the entry of concrete mixer truck. Even if the concrete mixer truck is sold as a second-hand car in the later stage, the invoice for the purchase of concrete mixer truck is required.

车辆合格证

Vehicle certificate

混凝土搅拌车合格证也是上户关重要的凭证，只有具有合格证的混凝土搅拌车才符合对机动车装备质量及有关标准的要求。

Only when the concrete mixer meets the requirements of the national standards and the quality certificate of the concrete mixer, can the concrete mixer meet the requirements of the relevant national standards.

三包保修卡

Three guarantees warranty card

混凝土搅拌车在一定时间和行驶里程内，如果出现因为质量问题所导致的故障和损坏，凭三包服务卡可以享受厂家的无偿服务。像是恶意人为损坏车辆不在三包范围

In case of failure and damage caused by quality problems within a certain time and mileage, the concrete mixer can enjoy the free service of the manufacturer with the three guarantee service card. For example, malicious man-made damage to the vehicle is not within the scope of three guarantees

核对铭牌

Check nameplate

购买混凝土搅拌车时特别要注意的是检查铭牌上的车架号、发动机型号、出厂日期是否与合格证一样。

When purchasing a concrete mixer, pay special attention to check whether the frame number, engine model and ex factory date on the nameplate are the same as those on the certificate.

随车附件

On board accessories

◆步骤二：外观检查

◆ step 2: appearance inspection

车身漆面检查

Body paint inspection

检查的时候与混凝土搅拌车保持平行状态，是在阳光下检查，利用阳光的反射来观察，毕竟新车的漆面都是一次性上好的，如果发现有色差，那肯定是后补的漆，很有可能是事故导致的。

When checking, keep parallel with the concrete mixer. It's best to check in the sun and observe it by using the reflection of the sun. After all, the paint surface of the new car is good at one time. If there is a color difference, it must be the paint repaired later, which is likely to be caused by the accident.

装配平整度

Assembly flatness

观察混凝土搅拌车保险杠、前面照、大灯、车门的缝隙是否均匀，其实这项对于老司机来说不难，但是新手司机可能困难一些，毕竟是次见车，其实新手司机掌握上面说的车漆面检查就可以了，漆面没问题一般就可以判定车辆没出过事故。

Observe whether the gaps in the bumper, front light, headlamp and door of the concrete mixer are uniform. In fact, this is not difficult for the old driver, but it may be more difficult for the novice driver. After all, it is the first time to see the car. In fact, the novice driver can master the above-mentioned car paint inspection. If the paint is OK, it can generally be judged that the car has not had an accident.

后视镜

Rearview mirror

各个后视镜都看一下，不是管是里面的，还是外面的检查混凝土搅拌车车门把手开关是否灵活，车门密封条是否完整；再将车门打开观察车门是否有下垂的现象，再将车门关闭，听是否有刺耳的金属敲击声，然后再对比两侧车门的关闭声音是否一致，如果是四门的车辆还要对比四个门的声音是否一样，或是后面两个相同

Check each rearview mirror, whether the tube is inside or outside. Check whether the door handle switch of the concrete mixer truck is flexible and whether the door sealing strip is complete; Then open the door, observe whether the door sags, then close the door, listen to whether there is a harsh metal knocking sound, and then compare whether the closing sound of the doors on both sides is consistent. If it is a four door vehicle, compare whether the sound of the four doors is the same, or whether the rear two are the same

检查钥匙

Check the key

检查每把钥匙是否可以开启、锁闭相对应的锁

Check whether each key can open and lock the corresponding lock

检查玻璃

Check the glass

检查混凝土搅拌车玻璃是否有划痕，特别是前风挡，要有良好的透光性，不能出现气泡，或是折射率异常的情况。

Check whether there are scratches on the glass of the concrete mixer, especially the front windshield. It should have good light transmittance, and there should be no bubbles or abnormal refractive index.

检查轮胎

Check the tires

查看全车轮胎有无磨损，不过在“背车”运输中的下车轮胎磨损会很大，还有就是看轮胎企业是否一样

Check whether the tires of the whole car are worn, but the tires of the car will be greatly worn in the "back car" transportation, and whether the tire brands are the same

底盘检查

Chassis inspection

先看混凝土搅拌车大梁是否变形，“背车”的下车一般会有这种情况出现，再看看有没有漏油的地方，什么后桥，发动机，变速箱等等，再查查底盘线路有没有磨损或是断掉的地方，可别以为“背车”的上车很安逸，照样有损坏。

First, check whether the girder of the concrete mixer truck is deformed. This situation usually occurs when you get off the truck. Then, check whether there is oil leakage, what rear axle, engine, gearbox, etc., and then check whether the chassis line is worn or broken. Don't think that the truck is easy to get on and still damaged.

◆步骤三：内饰检查

◆ step 3: interior trim inspection

清洁度

Cleanliness

检查座椅、卧铺

Check the seat and sleeper

混凝土搅拌车新车的座椅，卧铺和其它的内饰件都应该是有塑料套的，检查车辆的塑料套是否完整，坐在座椅上感觉座椅内部是否一异物，如果可以多方调节的座椅，应该进行测试，调试过程中有无异响是否平顺，头枕也不能放过。而卧铺则需要躺一下，感觉内部有无异物，上下铺都一样。在检查上卧铺折叠是否平顺，检查是否松动。

The seats, sleeper and other interior parts of the new concrete mixer should be covered with plastic covers. Check whether the plastic covers of the vehicle are complete and whether there is a foreign object inside the seat when sitting on the seat. If the seat can be adjusted in many ways, it should be tested to see if there is any abnormal noise during debugging, whether it is smooth, and whether the headrest can not be let go. The sleeper needs to lie down and feel whether there are foreign bodies inside. The upper and lower bunks are the same. Check whether the sleeper is folded smoothly and whether it is loose on the sleeper.

仪表台

Instrument panel

检查混凝土搅拌车仪表台是否整洁，有无划痕；在不插钥匙的情况下，检查各种按钮，看看按钮是不是都可靠，有没有按一下就掉下来的“脆弱”情况。再将点火开关放在打开状态，检查组合仪表的各项指示灯是否正常工作。在看看别的电子操作按钮能不能正常工作，例如：手动或电动玻璃升降器，空调调整钮，点烟器等等，一个都别落下。

Check whether the instrument panel of concrete mixer truck is clean and free of scratches; Without inserting the key, check all kinds of buttons to see if they are reliable and if there is a "fragile" situation that they fall down at the click of a button. Then put the ignition switch on and check whether the indicators of the combination instrument work normally. See if other electronic operation buttons can work normally, such as manual or electric window regulator, air conditioning adjustment button, cigarette lighter, etc. don't drop any of them.

杂物箱

Glove box

现在混凝土搅拌车的杂物箱很多，随便那个地方都用，而且还很“隐蔽”，所以要避免遗漏，检查封闭式的杂物箱开启、关闭是否顺畅，也可以检查里面是否有一些“不可告人的秘密”

At present, there are many glove boxes of concrete mixer truck, which can be used anywhere, and it is also very "hidden", so it is necessary to avoid omission. Check whether the closed glove box can be opened and closed smoothly, and whether there are some "hidden secrets" in it

带

Safety belt

带是保证驾驶人员生命的重要部分，所以一定要严格检查，拉开、自动回收、锁止的可靠性，应该平稳顺畅。模拟并检查带在发生作用时的可靠性。

The safety belt is an important part to ensure the life safety of drivers, so it must be strictly checked. The reliability of opening, automatic recovery and locking should be stable and smooth. Simulate and check the reliability of the safety belt when it works.

灯光

lighting

甭管什么近光灯、远光灯、转向灯、刹车灯……只要车上能亮的都仔细检查一遍，灯光应该明亮、稳定。别是大灯只亮一边的“独眼”，或是转向灯不闪。

Never mind the low beam, high beam, turn signal and brake lights... As long as the lights on the car can be checked carefully, the lights should be bright and stable. Don't be the "one eye" with only one side of the headlamp on, or the turn signal doesn't flash.

雨刮系统

Wiper system

检查混凝土搅拌车雨刮器喷水系统、刮水系统是否正常，别一盆水泊上来雨刮器刮的还没蒸发的快呢。雨刮器在刮水应没有“吱嘎……吱嘎……”的声音，如果有说明雨刮片已经老化。

Check whether the water spray system and wiper system of the wiper of the concrete mixer are normal. Don't park a basin of water. The wiper hasn't evaporated fast. There should be no "creak... Creak..." sound when the wiper is wiping. If there is, it indicates that the wiper blade has aged.
