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。

On the premise of meeting the above requirements, the price factor will be considered.

机构设计合理，操作方便，混凝土贮罐卸料要彻底

The mechanism design is reasonable, the operation is convenient, and the unloading of concrete tank should be thorough

这些全自动混凝土搅拌车使用中经常遇到的问题也须考虑到。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。

The problems often encountered in the use of these full-automatic concrete mixers should 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.

售后服务要好

After sales service was good

全自动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，是选型中须考虑的重要因素。

Full automatic concrete mixer truck is a special heavy vehicle, which has a small amount of possession and less sources 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 to be considered in the selection.

装载量要合适

The loading capacity should be appropriate

理论上说，全自动混凝土搅拌车的装载量越大，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8～9m38×4底盘的混凝土搅拌运输车要比装载量为6～7m36×4底盘的价格贵30%～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须充分考虑到。因此，确定车辆的装载量时定要综合考虑各方面的因素，不可顾此失彼。

In theory, the greater the loading capacity of the full-automatic concrete mixer truck, the higher the transportation efficiency, but this will also lead to a straight-line increase in vehicle purchase cost and a decline in trafficability. The price of concrete mixer truck with 8-9m38 × 4 chassis is 30% - 40% more expensive than that of 6-7m36 × 4 chassis. Meanwhile, 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, should be fully considered. Therefore, when determining the loading capacity of the vehicle, we must consider all factors comprehensively, and we can't neglect one and lose the other.

使用要可靠

Use it 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，绝对不允许搅拌运输车在工作时发生停机的故障，因此全自动混凝土搅拌车选型首先要考虑的就是车辆须十分可靠，关键部位如发动机和传动驱动装置发生故障的可能性要越低越好。

After the concrete is loaded into the vehicle, it is required to unload it to the working face within 2 hours or less, during which the mixing must be kept on; if the concrete can not 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, which will cause the concrete to solidify in the vehicle, resulting in the scrapping of the mixing truck. This puts forward strict requirements on the reliability of the mixer truck. It is absolutely not allowed to stop the mixer truck when it is working. Therefore, the first thing to consider in the selection of automatic concrete mixer truck is that the vehicle must be very reliable, and the lower the possibility of failure of key parts such as engine and driving device, the better.

混凝土贮罐及进、出料口要耐磨

The concrete storage tank and inlet and outlet shall be wear-resistant

沙和砾石是混凝土的主要组成成分。它们使全自动混凝土搅拌车混凝土贮罐及进、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5万～8万m3，混凝土贮罐内的螺旋叶片寿命只有3万～4万m3。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。
