选购要点一:使用要可靠
Key point 1: reliable use
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。因此混凝土搅拌车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 be unloaded to the working face within 2 hours or less, and must be continuously mixed during this period. If the concrete cannot be transported to the construction site within the specified time or the mixing is stopped for various reasons, the concrete in the truck will be scrapped. In serious cases, the concrete will solidify in the truck and the truck will be scrapped. This puts forward strict requirements for the reliability of the mixer truck, and does not allow the mixer truck to stop when it is working. Therefore, the first consideration of concrete mixer selection is that the vehicle must be very reliable, and the lower the possibility of failure of key parts such as engine and transmission drive device, the better.
选购要点二:装载量要合适
Key point 2: the 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底盘的混凝土搅拌车要比装载量为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。
In theory, the larger the loading capacity of transport vehicles, the higher the transport efficiency, but it will also lead to a sharp rise in vehicle purchase cost and a decline in trafficability. The loading capacity is 8-9m. The specific loading capacity of concrete mixer truck 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, the road condition of temporary construction road is very poor, and the problem of inconvenient movement of large vehicles, especially semi-trailer, must be fully considered. Therefore, when determining the loading capacity of the vehicle, we must take all factors into consideration.

选购要点三:混凝土贮罐及进、出料口要耐磨
Key point 3: the concrete storage tank and the 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 storage tank made of low alloy steel is 50000-80000 M. The service life of spiral blade in concrete storage 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 special wear-resistant steel and reinforced with wear-resistant materials in the easily worn parts, so their service life can be twice as long as that made of low alloy steel. It can be seen that different materials have different working life.
选购要点四:机构设计合理,操作方便,混凝土贮罐卸料彻底
Key points for purchase: reasonable mechanism design, convenient operation and complete discharge of concrete storage tank
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 discharge is not complete, more and more concrete will be left in the tank, which will reduce the capacity of the tank and make the cleaning very difficult.
选购要点五:售后服务要好
Five points of purchase: good after-sales service
混凝土搅拌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 is a kind of special heavy-duty vehicle, with less ownership and less 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 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
Key point 6: reasonable price
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车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的混凝土搅拌车。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 truck with 6-7m rear double axle chassis has a high performance price ratio, the semi-trailer with 10-12m loading capacity takes the second place, and the 8-10m8 × 4 chassis 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 projects, a small number of 10-12m semitrailers can be appropriately equipped. In this way, all kinds of needs can be taken into account, which is a more reasonable configuration.
