The self loading mixer can transport the concrete produced by the mixing plant or the aggregate sand, stone, cement and water mixed according to the proportion. During the transportation, the wet materials are continuously mixed slowly to prevent the initial setting and segregation of the concrete during the transportation. However, the time from production to pouring of concrete should not exceed 1.5h. How much is the self loading mixer to avoid concrete setting.

所以，在更远距离运输的情况下，需采用干料和半干料搅拌运输车来运送。干料式搅拌运输车可按配比将干状骨料和水泥直接装入该车的搅拌筒内，在运输过程中筒内的干料进行搅拌，当车辆将要到达施工场地或在施工场地再加水完成混凝土的搅拌。

Therefore, in the case of longer distance transportation, the dry and semi dry material mixing truck should be used for transportation. The dry material mixer truck can directly load the dry aggregate and cement into the mixing drum of the truck according to the proportion. During the transportation, the dry material in the drum is mixed. When the truck is about to arrive at the construction site or in the construction site, water is added to complete the concrete mixing.

半干料式搅拌运输车所装运的混凝土中的骨料和水泥也是按配比配制的，并含有一定的水，自上料搅拌车报价，但水的含量达不到浇注要求，需在车辆将要达到施工场地或在施工场地加水搅拌。

The aggregate and cement in the concrete transported by the semi dry material mixing truck are also prepared according to the proportion, and contain a certain amount of water. The price is quoted from the feeding mixing truck, but the water content does not meet the pouring requirements, so it is necessary to add water to the construction site or when the vehicle is about to reach the construction site.

搅拌车手刹系统都是作用在后轮上的。而因为后轮制动器的形式不同，手刹又有两种工作环境：在安装鼓式制动器的后轮上，由于鼓式制动器本身就可以兼作驻车制动器。

The hand brake system of the mixer truck acts on the rear wheel. Because of the different forms of the rear wheel brake, the handbrake has two working environments: on the rear wheel with drum brake, the drum brake itself can also be used as the parking brake.

因此在驻车时刹车鼓内的蹄片和摩擦片相接合，这样就可以产生制动力。而在安装碟式制动器的后轮上，由于没有刹车鼓，因此则必须在刹车碟的中心部位安装额外的驻车刹车鼓来使手刹完成制动工作。

Therefore, when parking, the shoes and friction plates in the brake drum are engaged, which can generate braking force. In the rear wheel with disc brake, there is no brake drum, so it is necessary to install additional parking brake drum in the center of the brake disc to complete the brake work.

在行使过程中不可避免会遇到特殊情况而采取紧急制动加上搅拌筒本身有一定的倾角，所以副车架前台承受的载荷相对来说要大得多，而这一部分载荷主要加在联接减速机与前支撑座的六个螺栓上。

In the process of running, it is inevitable to encounter special circumstances and take emergency braking. In addition, the mixing drum itself has a certain inclination angle, so the load on the front desk of the subframe is much larger, and this part of the load is mainly added on the six bolts connecting the reducer and the front support seat.

为防止螺栓发生被剪断而酿成事故，使螺栓不受到剪切力的影响，确保车辆运行中的。为满足搅拌车的填充率，搅拌筒还要满足一定的倾角要求。减速机和前台支撑架在装配后已经固连为一体，无法对搅拌筒产生有效的支撑。

In order to prevent the bolt from being sheared and causing accidents, make the bolt not affected by the shear force, and ensure the safety of the vehicle in operation. In order to meet the filling rate of the mixer, the mixing drum should also meet certain inclination requirements. The reducer and the front support frame have been fixed as a whole after assembly, which can not effectively support the mixing drum.

这时整个结构就相当于一个悬臂梁。这对于减速机来说会产生很大的扭转力矩。为防止由此给减速机带来的危害，支重滚轮搅拌泵送一体机经济效益。

At this time, the whole structure is equivalent to a cantilever beam. This will produce a lot of torque for the reducer. In order to prevent the harm to the reducer, the economic benefit of the roller mixing pumping machine is improved.
