Concrete mixer is the main special vehicle in construction engineering, maintenance is very important, especially the parts which are frequently used. Only after maintenance can the service life of mixer truck be increased. To see how to maintain the vulnerable parts of mixer truck. What are the vulnerable parts of concrete mixer? The easily damaged parts mainly refer to the parts used frequently on the mixer, such as hydraulic system, supporting roller, raceway, water tank, engine and so on.

说托轮，我们都知道 混凝土搅拌机在行驶过程中罐体是一直转动的，这样才能保证罐内的混凝土不凝固，不离析，罐体的转动离不开托轮和滚道，这两个部位一旦出问题就会造成非常严重的后果——混凝土凝结。所以这两个部位的保养是长久性的，托轮和滚道之间要经常涂抹润滑油，对于滚道上的污物要及时清理，以免影响罐体转动。

First of all, we all know that the tank of the concrete mixer is always rotating in the process of driving, so as to ensure that the concrete in the tank does not solidify or segregate. The rotation of the tank can not be separated from the supporting wheel and the raceway. Once these two parts fail, it will cause a very serious consequence concrete condensation. Therefore, the maintenance of these two parts is long-term. Lubricating oil should be applied between the roller and the raceway. The dirt on the raceway should be cleaned up in time to avoid affecting the rotation of the tank.
             

混凝土搅拌机上的液压系统也是非常重要的，搅拌罐侧操作主要是依靠液压系统来实现的，它的保养也是关重要的，比如液压油要定期更换，不要使用劣质液压油，对于液压软件要经常检查，润滑度不够的要及时添加润滑油脂，如有损伤元件要及时更换，保证液压系统的灵活使用。

The hydraulic system on the concrete mixer is also very important. The side operation of the mixing tank mainly depends on the hydraulic system, and its maintenance is also very important. For example, the hydraulic oil should be replaced regularly, and the inferior hydraulic oil should not be used. The hydraulic software should be checked frequently. If the lubrication is insufficient, the lubricating grease should be added in time. If there is damage, the components should be replaced in time to ensure the liquid Flexible use of pressure system.

混凝土搅拌机上水箱的大小及安装部位都是厂家经过设计师的精心设计的，所以不要随意的改动，水箱的视水管和过滤网偶尔也要查看一下，视情况更换，以免引起堵塞，影响水位的判断，在冬天工作完成后要及时的将水箱内的水排出，以免结冰引起水箱开裂。

The size and installation position of the water tank on the concrete mixer are carefully designed by the manufacturer through the designer, so do not change it at will. The inspection pipe and filter screen of the water tank should be checked occasionally and replaced according to the situation, so as not to cause blockage and affect the judgment of water level. After the completion of the work in winter, the water in the water tank should be discharged in time to prevent the water tank from cracking due to freezing.

发动机的使用也是非常多的，所以对发动机的保养也要注意，尤其是机油，要经常查看机油，发现机油变质要及时更换，油量变少要及时添加。对于新买的 混凝土搅拌机要注意螺栓，因为新车在使用一段时间后各部位的螺栓容易松动，所以在使用的过程中要十分注意，发现松动螺栓及时紧固；新车的行驶速度不易过快也不易过慢，要按规定的时间进行保养。

The use of the engine is also very much, so attention should be paid to the maintenance of the engine, especially the engine oil. The engine oil should be checked frequently. If the oil deteriorates, it should be replaced in time. If the oil quantity decreases, it should be added in time. For the newly purchased concrete mixer, attention should be paid to the bolts. Since the bolts in various parts of the new car are easy to loosen after using for a period of time, great attention should be paid in the use process, and the loose bolts should be tightened in time; the driving speed of the new car is not easy to be too fast or too slow, and maintenance should be carried out according to the specified time.
