Concrete mixer truck is also known as cement mixer, mixing tank truck, commercial mixer truck, snail truck, etc., which are called different names according to different regions. The chassis of concrete mixer produced in China mostly adopts the second class general chassis provided by vehicle manufacturers. Its special mechanism mainly includes power take-off, front and rear bracket of mixing drum, reducer, hydraulic system, mixing drum, control mechanism, cleaning system, etc. So, what are the key points of purchasing concrete mixer? The following concrete mixer for you to introduce.

　　选购要点一：使用要可靠

　　Purchase point 1: use reliably

　　混凝土装入车内以后，要求在2h或更短的时间内卸到工作面上，在此期间必须不停地搅拌。如果在规定时间内不能运到工地或因各种原因停止搅拌，车内混凝土就会报废，严重的会导致混凝土凝固在车内，造成搅拌运输车报废。这对搅拌运输车的可靠性提出了严格的要求，不允许搅拌运输车在工作时发生停机的故障。因此混凝土搅拌机选型首先要考虑的就是车辆必须十分可靠，关键部位如发动机和传动一驱动装置发生故障的可能性要越低越好。

　　After the concrete is loaded into the truck, it is required to unload the concrete to the working face within 2 hours or less, during which the concrete must be continuously mixed. If the concrete can not be transported to the construction site within the specified time or stop mixing for various reasons, the concrete in the truck will be scrapped, which will cause the concrete to solidify in the vehicle seriously, which will cause the mixing truck to be scrapped. This puts forward strict requirements for the reliability of the mixer truck, and it is not allowed to stop the mixer truck when it is working. Therefore, the first thing to consider in the selection of concrete mixer is that the vehicle must be very reliable, and the possibility of failure of key parts such as engine and transmission drive device should be as low as possible.

　　选购要点二：装载量要合适

　　Purchase key point 2: loading capacity should be appropriate

　　理论上说，运输车辆的装载量越大，运输效率越高，但这也会导致车辆购置成本直线上升和通过性下降。装载量为8～9m。8×4底盘的混凝土搅拌机要比装载量为6～7m。6×4底盘的价格贵309/5～40%，同时，建筑工地一般地域狭小，临时施工道路路况很差，大车尤其是半挂车行动不便的问题必须充分考虑到。因此，确定车辆的装载量时一定要综合考虑各方面的因素，不可顾此失彼。

　　Theoretically speaking, the larger the loading capacity of transport vehicles, the higher the transportation efficiency, but this will also lead to the straight-line increase of vehicle purchase cost and the decrease of trafficability. The loading capacity is 8-9 M. The specific loading capacity of concrete mixer with 8 × 4 chassis is 6-7m. The price of 6 × 4 chassis is 309 / 5 ~ 40% expensive. At the same time, the construction site is generally narrow, and the road condition of temporary construction road is very poor. The problem of inconvenient movement of large vehicles, especially semi-trailer, must be fully considered. Therefore, when determining the loading capacity of vehicles, we must consider all factors comprehensively, and we can't neglect one and lose the other.
              

　　选购要点三：混凝土贮罐及进、出料口要耐磨

　　Purchase point 3: concrete tank and inlet and outlet should be wear-resistant

　　沙和砾石是混凝土的主要组成成分。它们使混凝土贮罐及进、出料口在工作时磨损严重。一般情况下，采用低合金钢制造的混凝土贮罐使用寿命为5～8万m。混凝土贮罐内的螺旋叶片寿命只有3～4万m。。国产混凝土贮罐一般由高强度低合金钢钢材制成，比普通A3钢材耐磨提高1～2倍。一些进口混凝土贮罐采用锰硼专用耐磨钢材，并且在易磨损部位镶耐磨材料加固，因此其使用寿命比低合金钢制造的又可提高1倍。由此可知，采用材料不同其工作寿命则大不相同。

　　Sand and gravel are the main components of concrete. They make the concrete storage tank and the inlet and outlet wear seriously. In general, the service life of concrete tank made of low alloy steel is 50000-80000 M. The service life of spiral blade in concrete tank is only 30000-40000 M.. Domestic concrete tanks are generally made of high strength low alloy steel, which is 1-2 times more wear-resistant than ordinary A3 steel. Some imported concrete tanks are made of manganese boron wear-resistant steel, and the wear-resistant materials are inlaid in the easily worn parts. Therefore, the service life of these tanks can be doubled compared with those made of low-alloy steel. It can be seen that the working life of different materials is quite different.

　　选购要点四：机构设计合理，操作方便，混凝土贮罐卸料彻底

　　The fourth point of purchase: the mechanism design is reasonable, the operation is convenient, and the discharge of concrete tank is complete

　　这些使用中经常遇到的问题也必须考虑到。比如若卸料不完全，留在罐内的混凝土就会越积越多，使贮罐容量减小，并且清理十分困难。

　　These problems often encountered in use must also be considered. For example, if the unloading is not complete, the concrete left in the tank will accumulate more and more, which will reduce the tank capacity and is very difficult to clean.

　　选购要点五：售后服务要好

　　Purchase point 5: better after-sales service

　　混凝土搅拌机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 is a kind of special heavy-duty vehicle, which has a small quantity and a small source of accessories. Compared with general motors, it is more dependent 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

　　选购要点六：价格要合理

　　The price should be reasonable

　　在满足上述要求的前提下再考虑价格因素。装载量为6～7m后双桥底盘的混凝土搅拌机是性能价格比高的车型，装载量为10～12m的半挂车次之，装载量为8～10m8×4底盘的性能价格比低。因此一般选用6～7m的混凝土搅拌机。另外，为满足个别大型工程的需要，可适当配少量10～12m的半挂车。这样可以兼顾各种需要，是比较合理的配置。

　　On the premise of meeting the above requirements, the price factor will be considered. The concrete mixer with double axle chassis with a loading capacity of 6-7m is the vehicle with high performance price ratio, the semi-trailer with 10-12m loading capacity takes the second place, and the chassis with 8-10m8 × 4 loading capacity has a low performance price ratio. Therefore, 6-7m concrete mixer is generally selected. In addition, in order to meet the needs of individual large-scale projects, a small number of 10-12m semi-trailer can be properly equipped. This can take into account various needs, is a more reasonable configuration.
