The function of the driving device is to drive the rotation of the concrete storage tank. It consists of power take-off, cardan shaft, hydraulic pump, hydraulic motor, control valve, hydraulic oil tank and cooling device. For concrete mixers, the drive is still very important, so let's take a closer look.

1.萬向旋轉部分是經常發生故障的部分。應及時添加油脂，應經常檢查磨損情況，并及時進行修理和更換。團隊應該有一個備用的萬向軸組件，以確保萬一發生故障，它可以在數十分鐘內恢復工作。

1. The universal rotating part is the part that often breaks down. Grease shall be added in time, wear condition shall be checked frequently, and repair and replacement shall be carried out in time. The team should have a spare cardan shaft assembly to ensure that in the event of a failure, it can return to work in dozens of minutes.

2.確保液壓油清潔。水泥自動攪拌車的工作環境惡劣，必須防止臟的水泥砂進入液壓系統。應根據手冊要求定期更換液壓油。在檢查期間發現液壓油與水或沙子混合后，有必要立即停止機器以清潔液壓系統并更換液壓油。

2. Make sure the hydraulic oil is clean. The working environment of concrete mixer is bad, so it is necessary to prevent the dirty cement sand from entering the hydraulic system. The hydraulic oil should be changed regularly according to the manual. When it is found that the hydraulic oil is mixed with water or sand during the inspection, it is necessary to stop the machine immediately to clean the hydraulic system and replace the hydraulic oil.

3.確保液壓油冷卻裝置有效。必須定期清潔液壓油散熱器，以防止散熱器被水泥堵塞，檢查散熱器的電風扇是否正常運行，并防止液壓油溫度超過標準。只要清潔液壓油，液壓零件的故障就不會很多，但是不同制造商的使用壽命會有所不同。

3. Ensure that the hydraulic oil cooling device is effective. It is necessary to clean the hydraulic oil radiator regularly to prevent the radiator from being blocked by cement, check whether the electric fan of the radiator operates normally, and prevent the temperature of the hydraulic oil from exceeding the standard. As long as the hydraulic oil is cleaned, there will not be many failures of hydraulic parts, but the service life of different manufacturers will be different.

一般而言，如果驅動裝置由于故障而停止工作，則混凝土儲罐將無法正常旋轉，這也將導致車輛中的混凝土報廢，甚至整個混凝土罐都將凝結在罐中，從而導致要報廢的水泥自動攪拌車。因此，驅動裝置是否可靠是使用中必須注意的問題。

Generally speaking, if the driving device stops working due to failure, the concrete tank will not rotate normally, which will also lead to the scrapping of concrete in the vehicle, and even the whole concrete tank will condense in the tank, resulting in the scrapped concrete mixer. Therefore, whether the driving device is reliable or not is a problem that must be paid attention to in use.
