1. Mixer chassis

专用汽车底盘是自上料混凝土搅拌罐车组成中成本、使用中维护费用的部分。对于底盘，主要看该底盘的发动机功率和扭矩、油耗、轮胎、车架、驾驶舒适性及排放标准等方面。用户在选用时除应考虑该汽车底盘本身性能和该底盘能否得到汽车底盘制造商及时的维修支持和配件供给之外，还要考虑当地的排放要求、购买者的资金实力和对运输量的饱满程度的要求，工作量越饱满，对搅拌运输车的可靠性要求越高。

The chassis of special purpose vehicle is the part with the highest cost and the highest maintenance cost in use. For the chassis, focus on the chassis engine power and torque, fuel consumption, tires, frame, driving comfort and emission standards. When selecting, users should not only consider the performance of the chassis itself and whether the chassis can get timely maintenance support and parts supply from the chassis manufacturer, but also consider the local emission requirements, the buyer's financial strength and the requirements for the fullness of the transportation volume. The fuller the workload is, the higher the reliability requirements of the mixer truck are.

2.液压传动件

2. Hydraulic transmission parts

混凝土搅拌运输车由于工况恶劣，所以对液压传动件的质量、可靠性要求相当高。目前液压传动系统市场上有两种配置：一种是分体式配置，由液压油泵、液压马达、冷却器和减速机组成，该配置成熟可靠，维修方便；另一种是三合一式配置，由液压油泵、三合一减速机（内含液压马达、散热器、减速机）组成，该配置集成度高，安装方便，外形美观，但由于液压系统用油与减速机用油是同一种油，所以对油的要求较严格。

Due to the bad working conditions of concrete mixer truck, the quality and reliability of hydraulic transmission parts are required to be quite high. At present, there are two configurations of hydraulic transmission system in the market: one is split configuration, which is composed of hydraulic oil pump, hydraulic motor, cooler and reducer, which is mature and reliable and easy to maintain; the other is three in one configuration, which is composed of hydraulic oil pump and three in one reducer (including hydraulic motor, radiator and reducer). The configuration is highly integrated, easy to install and external The shape is beautiful, but because the hydraulic system oil and the reducer oil are the same kind of oil, so the oil requirements are more strict.

3.整车性能

3. Vehicle performance

经改装后的整车性能主要体现在操纵性、横向稳定性及搅拌筒的性能等方面。操纵性：主要反映在重载时驾驶员转向的操纵感觉。搅拌车所装混凝土为半流体，特别是坍落度较大，车辆在坡上起步时会向后移动，选购时要特别注意。横向稳定性：重载搅拌运输车转弯时的速度及的高低对横向稳定性的影响较大。目前市场上8立方米搅拌车搅拌筒的倾斜角度一般为15°，也有个别是13°。角度越小，对的降低就越有利，同时在通过性和出料性方面也有改善。搅拌筒：对搅拌筒的性能产生影响的主要是搅拌叶片的布置。

The performance of the modified vehicle is mainly reflected in the maneuverability, lateral stability and the performance of the mixing drum. Maneuverability: mainly reflected in the steering feeling of the driver under heavy load. The concrete in the mixer truck is semi fluid, especially with large slump. When the vehicle starts on the slope, the center of gravity will move backward, so special attention should be paid when purchasing. Lateral stability: the turning speed and center of gravity of heavy haul mixer truck have great influence on lateral stability. At present, the inclination angle of the mixing drum of 8 cubic meters mixer truck is generally 15 degrees, and some of them are 13 degrees. The smaller the angle is, the more favorable it is to reduce the center of gravity and improve the trafficability and discharge performance. Mixing drum: the main factor affecting the performance of mixing drum is the arrangement of mixing blades.

4.性价比

4. Cost performance

在满足上述要求的前提下再考虑因素。装载量为8-10立方米的6×4底盘混凝土搅拌运输车是性价比的车型，

On the premise of meeting the above requirements, the price factor will be considered. The 6 × 4 chassis concrete mixer truck with a loading capacity of 8-10 cubic meters is the most cost-effective model,

5.售后服务

5. After sales service

混凝土搅拌运输车是一种专用重型车辆，保有量少，配件来源少，与一般通用汽车相比，对厂家的售后服务依赖性较大。因此，厂家是否能提供方便快捷可靠的售后服务，是选型中必须考虑的重要因素。

Concrete mixer truck is a kind of special heavy-duty vehicle, which has a small amount of possession and less sources of accessories. Compared with general motors, it depends more on the manufacturer's after-sales service. Therefore, whether the manufacturer can provide convenient, fast and reliable after-sales service is an important factor that must be considered in the selection.
