1. The suspender is an important structural part of the feeding mixer. Once the boom is damaged or the service life is over, the feeding agitator will lose its original meaning. There is no boom for the pump truck. I think we can only call the pump truck. Therefore, the service life of the boom directly determines the service life of the loading part of the feeding mixer.

2.臂架的使用寿命长取决于臂架采用高强度钢，采用较轻的设计，并优化泵送系统的压力，减少泵送混凝土对臂架的影响。同时，对手臂的日常保养和保养，也是提高手臂使用寿命的关键。因为更换手臂的费用太高，所以，当多节手臂在出现损坏时，有些人宁愿选择放弃对其进行保养。在那一点上，自装混合器的生命结束了。

2. The long service life of the boom depends on the use of high-strength steel, lighter design, and optimization of the pressure of the pumping system to reduce the impact of pumping concrete on the boom. At the same time, the daily maintenance of the arm is also the key to improve the service life of the arm. Because the cost of replacing the arm is too high, some people prefer to give up maintenance when the multi arm is damaged. At that point, the life of the self-contained mixer is over.

3.底盘从进料混合器的重要性是不言而喻的，如果底盘不能正常工作，也不能为安装的液压系统提供动力，这时，也只能选择报废。要延长底盘的使用寿命，关键的还是定期保养。同时，一些坏习惯应该避免在日常驾驶。例如，空转的出租车，对于泵车等重车来说，是对变速箱非常损坏的。因此，底盘的使用寿命也可能与驾驶员的驾驶方式有关。

3. The importance of the chassis from the feed mixer is self-evident. If the chassis can not work normally and can not provide power for the installed hydraulic system, it can only be scrapped. To extend the service life of the chassis, the key is regular maintenance. At the same time, some bad habits should be avoided in daily driving. For example, idling taxis, for heavy vehicles such as pump trucks, are very damaging to the gearbox. Therefore, the service life of the chassis may also be related to the driver's driving style.
