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.
混凝土搅拌车的万向转动部分是故障多发部位，应按时加注润滑脂，并经常检查磨损情况，及时修理更换。车应有备用的万向轴总成，以保证一旦发生故障能在及时分钟内恢复工作，保证液压清洁。混凝土搅拌车工作环境恶劣，一定防止污水泥砂进入液压系统。液压油要按使用手册要求定期更换。一旦检查时发现液压油中混入水或泥砂，就要立即停机清洗液压系统、更换液压油。
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.
保证混凝土搅拌车以上部分因故障停止工作，混凝土搅拌罐将不能转动，这会导致车内混凝土报废，严重的甚使整罐混凝土凝结在罐内，造成 混凝土搅拌运输车报废。
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.
