The driving device of small concrete mixer is used to drive the rotation of concrete tank and vehicle. It is composed of power take-off, universal shaft, hydraulic pump, hydraulic motor, control valve, hydraulic oil tank and cooling device. Therefore, whether the driving device of concrete mixer is reliable or not is a problem that must be attached great importance to in use. In order to ensure the integrity and reliability of the mixer drive device, the following practice can be referred to.
混凝土攪拌車的萬向轉動部分是故障多發部位，應按時加注潤滑脂，並經常檢查磨損情況，及時修理更換。車應有備用的萬向軸總成，以保證一旦發生故障能在及時分鍾內恢複工作，保證液壓清潔。混凝土攪拌車工作環境惡劣，一定防止汙水泥砂進入液壓係統。液壓油要按使用手冊要求定期更換。一旦檢查時發現液壓油中混入水或泥砂，就要立即停機清洗液壓係統、更換液壓油。
The universal rotating part of the concrete mixer truck is a fault prone part, so grease should be added on time, and the wear condition should be checked regularly, and the timely repair and replacement should be carried out. The car should have spare cardan shaft assembly to ensure that once the fault occurs, it can resume work within minutes in time and ensure the hydraulic cleaning. The working environment of the concrete mixer truck is bad, so the dirty cement sand must be prevented from entering the hydraulic system. The hydraulic oil should be replaced regularly according to the requirements of the manual. Once it is found that the hydraulic oil is mixed with water or sand, it is necessary to stop the machine immediately to clean the hydraulic system and replace the hydraulic oil.
保證混凝土攪拌車以上部分因故障停止工作，混凝土攪拌罐將不能轉動，這會導致車內混凝土報廢，嚴重的甚至使整罐混凝土凝結在罐內，造成 混凝土攪拌運輸車報廢。
To ensure that the above parts of the concrete mixer truck stop working due to fault, the concrete mixing tank will not rotate, which will lead to the scrapping of the concrete in the truck, and even make the whole tank of concrete coagulate in the tank, resulting in the scrapping of the concrete mixer truck.
