For the concrete mixer truck, because of its high price, it is worthy of special attention. However, although the concrete mixer is made of steel, it also has a life cycle just like people. In the period of divergence, the physical condition of the mixer is very different.

混凝土自動上料攪拌車的使用周期及壽命是多少年，我們將周期劃分為巔峰期、微軟期、更年期、暮年期和危險期五個階段。在這五個階段，對混凝土攪拌車的保養、維修重點上也各不一樣。

How many years is the service life and service life of the automatic concrete feeding mixer? We divide the cycle into five stages: peak period, Microsoft period, menopause period, twilight period and dangerous period. In these five stages, the maintenance and repair of concrete mixer truck are also different.

1~2年巔峰期，混凝土攪拌車使用的前兩年，是生命的巔峰期，可以說是混凝土攪拌車使用狀況最佳的時分，相當于人的青年期。這個期間的人滿懷熱情、敢闖敢做，似乎不會倦怠。

The peak period of 1-2 years, the first two years of the use of concrete mixer truck is the peak period of life, which can be said to be the best time for the use of concrete mixer truck, which is equivalent to the youth period of people. During this period, people are full of enthusiasm and dare to do something, and they don't seem to be tired.

處于這個期間的混凝土攪拌車也是如此，車況極好，只需保持慣例保養，根本上不會有什么問題，但有些質量不怎么過硬水泥攪拌車，巔峰期只能對峙一年左右。所以，新車第一年行使進程中根本不會出什么大的質量問題，然則運用兩年以上的混凝土攪拌車就要逐步初步改換一些最易損耗的部件。

The concrete mixer truck in this period is also the same. The condition of the truck is excellent. As long as the routine maintenance is required, there will be no problem at all. However, some cement mixers are of poor quality, and the peak period can only last about one year. Therefore, the new car in the first year of driving process will not have any major quality problems, but the use of more than two years of concrete mixer truck will gradually change some of the most vulnerable parts.

2~4年微軟期，這個階段，混凝土攪拌車初步進入了微軟期。不再像前期那樣龍精虎猛。這個期間的混凝土攪拌車，需求常常改換一些部件，給其增補能量。起首需求改換新的剎車皮。剎車皮是駕駛平安的首道防地。依據閱歷，剎車皮大約在兩年左右就會磨荊此時，燃油泵也差不多該清洗或改換。假定混凝土攪拌車跑起來不安寧穩，就應該反省車子的減振器。假定減振器的彈簧落空彈性，下雨天行駛就十分風險。

2-4 years of Microsoft period. At this stage, the concrete mixer truck has initially entered the Microsoft period. It's not as vigorous as it was in the early days. During this period, the concrete mixer needs to change some parts to supplement energy. At first, new brake pads were needed. The brake skin is the first defense for safe driving. According to experience, the brake skin will wear in about two years. At this time, the fuel pump should be cleaned or replaced. Assuming that the concrete mixer runs restlessly and stably, we should reflect on the shock absorber of the truck. Assuming that the spring of the shock absorber is elastic, driving on rainy days is very risky.

沙和礫石是混凝土的主要組成成分。它們使混凝土貯罐及進、出料口在工作時磨損嚴重。由于每個廠家罐體制造材料不同其工作壽命則大不相同。

Sand and gravel are the main components of concrete. They make the concrete storage tank and the inlet and outlet wear seriously. Due to the different manufacturing materials of the tank body of each manufacturer, its working life is quite different.
