◆ step 1: check relevant certificates

隨車證件關乎到上戶，保修等情況

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

購車發票

Purchase invoice

首先要檢查購買混凝土攪拌車發票，混凝土攪拌車購車發票非常重要，是最重要的購車證明，同時也是混凝土攪拌車上戶的憑證，就算到后期混凝土攪拌車當做二手車出售都需要購車發票。

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.

車輛合格證

Vehicle certificate

混凝土攪拌車合格證也是上戶至關重要的憑證，只有具有合格證的混凝土攪拌車才符合國家對機動車裝備質量及有關標準的要求。

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

混凝土攪拌車在一定時間和行駛里程內，如果出現因為質量問題所導致的故障和損壞，憑三包服務卡可以享受廠家的無償服務。像是惡意人為損壞車輛不在三包范圍

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

核對銘牌

Check nameplate

購買混凝土攪拌車時特別要注意的是檢查銘牌上的車架號、發動機型號、出廠日期是否與合格證一樣。

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.

隨車附件

On board accessories

◆步驟二：外觀檢查

◆ step 2: appearance inspection

車身漆面檢查

Body paint inspection

檢查的時候與混凝土攪拌車保持平行狀態，最好是在陽光下檢查，利用陽光的反射來觀察，畢竟新車的漆面都是一次性上好的，如果發現有色差，那肯定是后補的漆，很有可能是事故導致的。

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.

裝配平整度

Assembly flatness

觀察混凝土攪拌車保險杠、前面照、大燈、車門的縫隙是否均勻，其實這項對于老司機來說不難，但是新手司機可能困難一些，畢竟是第一次見車，其實新手司機掌握上面說的車漆面檢查就可以了，漆面沒問題一般就可以判定車輛沒出過事故。

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.

后視鏡

Rearview mirror

各個后視鏡都看一下，不是管是里面的，還是外面的檢查混凝土攪拌車車門把手開關是否靈活，車門密封條是否完整；再將車門打開觀察車門是否有下垂的現象，再將車門關閉，聽是否有刺耳的金屬敲擊聲，然后再對比兩側車門的關閉聲音是否一致，如果是四門的車輛還要對比四個門的聲音是否一樣，或是后面兩個相同

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

檢查鑰匙

Check the key

檢查每把鑰匙是否可以開啟、鎖閉相對應的鎖

Check whether each key can open and lock the corresponding lock

檢查玻璃

Check the glass

檢查混凝土攪拌車玻璃是否有劃痕，特別是前風擋，要有良好的透光性，不能出現氣泡，或是折射率異常的情況。

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.

檢查輪胎

Check the tires

查看全車輪胎有無磨損，不過在“背車”運輸中的下車輪胎磨損會很大，還有就是看輪胎品牌是否一樣

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

底盤檢查

Chassis inspection

先看混凝土攪拌車大梁是否變形，“背車”的下車一般會有這種情況出現，再看看有沒有漏油的地方，什么后橋，發動機，變速箱等等，再查查底盤線路有沒有磨損或是斷掉的地方，可別以為“背車”的上車很安逸，照樣有損壞。

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.

◆步驟三：內飾檢查

◆ step 3: interior trim inspection

清潔度

Cleanliness

檢查座椅、臥鋪

Check the seat and sleeper

混凝土攪拌車新車的座椅，臥鋪和其它的內飾件都應該是有塑料套的，檢查車輛的塑料套是否完整，坐在座椅上感覺座椅內部是否一異物，如果可以多方調節的座椅，應該進行測試，調試過程中有無異響是否平順，頭枕也不能放過。而臥鋪則需要躺一下，感覺內部有無異物，上下鋪都一樣。在檢查上臥鋪折疊是否平順，檢查是否松動。

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.

儀表臺

Instrument panel

檢查混凝土攪拌車儀表臺是否整潔，有無劃痕；在不插鑰匙的情況下，檢查各種按鈕，看看按鈕是不是都可靠，有沒有按一下就掉下來的“脆弱”情況。再將點火開關放在打開狀態，檢查組合儀表的各項指示燈是否正常工作。在看看別的電子操作按鈕能不能正常工作，例如：手動或電動玻璃升降器，空調調整鈕，點煙器等等，一個都別落下。

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.

雜物箱

Glove box

現在混凝土攪拌車的雜物箱很多，隨便那個地方都用，而且還很“隱蔽”，所以要避免遺漏，檢查封閉式的雜物箱開啟、關閉是否順暢，也可以檢查里面是否有一些“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

安全帶

Safety belt

安全帶是保證駕駛人員生命安全的重要部分，所以一定要嚴格檢查，拉開、自動回收、鎖止的可靠性，應該平穩順暢。模擬并檢查安全帶在發生作用時的可靠性。

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.

燈光

lighting

甭管什么近光燈、遠光燈、轉向燈、剎車燈……只要車上能亮的都仔細檢查一遍，燈光應該明亮、穩定。別是大燈只亮一邊的“獨眼”，或是轉向燈不閃。

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.

雨刮系統

Wiper system

檢查混凝土攪拌車雨刮器噴水系統、刮水系統是否正常，別一盆水泊上來雨刮器刮的還沒蒸發的快呢。雨刮器在刮水應沒有“吱嘎……吱嘎……”的聲音，如果有說明雨刮片已經老化。

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.
