Concrete mixer truck is a special truck used to transport construction concrete; because of its shape, it is often called snail truck. During the actual operation of the equipment, the handling of self loading mixing truck is also a very important part. Therefore, we need to test the quality of engine oil in the process of application, so how to operate?

1、将自混凝土搅拌车停在水平表面上并拧紧手刹。

1. Park the self mixing truck on a horizontal surface and tighten the hand brake.

2、让发动机怠速作业几分钟。

2. Let the engine idle for a few minutes.

3、踩下制动踏板，将操纵杆转倒档，前进档等，并在每个档上停留几秒钟，以向变矩器和所有换档执行器注满液压油，终将操纵杆转到停车方位。

3. Press the brake pedal, turn the control lever to reverse, forward, etc., and stay in each gear for a few seconds to fill the torque converter and all shift actuators with hydraulic oil, and finally turn the control lever to the parking position.

4、从加油管上取下自动变速箱油尺，将清洁过的油尺插入加油管，然后将其拉出以检查油尺上的油位。

4. Remove the automatic transmission oil dipstick from the oil filling pipe, insert the cleaned oil dipstick into the oil filling pipe, and then pull it out to check the oil level on the oil dipstick.

在检查中科混凝土搅拌车或对其进行缺点排除之前，请先检查变速箱油位和油质。将变速杆置于P方位，在空转时作业发动机少几分钟，油液抵达正常的作业温度，并且车辆有停放在水平表面上，以确保差速器和油门之间的油位。传输通常是安稳的。

Please check the oil level and quality of the gearbox before checking Zhongke concrete mixer or eliminating its defects. Put the gear lever in position P and operate the engine at idle for at least a few minutes. The oil reaches the normal operating temperature and the vehicle is parked on a horizontal surface to ensure the oil level between the differential and the throttle. The transmission is usually secure.

1、进水体系可根据称重设置完成自动进水。

1. The water inlet system can automatically feed water according to the weighing setting.

2、自上料拌和车滚筒的旋转由液压马达经过特别的行星齿轮驱动，行星齿轮的输出轴可以以恒定视点摇晃，以满意在严厉的路途条件下自上料拌和车滚筒的节拍。

2. The rotation of the drum of the self feeding mixer is driven by the hydraulic motor through a special planetary gear. The output shaft of the planetary gear can swing at a constant angle to satisfy the beat of the drum of the self feeding mixer under severe road conditions.

3、双螺旋叶片安置在自动混凝土拌和车的拌和筒的内壁上，正向进给和混凝土拌和，而反向旋转的混凝土在螺旋叶片的向下压力下从出口排出。

3. The double spiral blades are arranged on the inner wall of the mixing cylinder of the automatic concrete mixing truck, which feed forward and mix the concrete, while the counter rotating concrete is discharged from the outlet under the downward pressure of the spiral blades.

4、供应干物料，根据规划比例自动供应铲斗臂，动臂油缸和计量料斗。

4. Supply dry materials, automatically supply bucket arm, boom cylinder and metering hopper according to the planning proportion.

5、液压体系运用恒功率可变排量活塞泵以削减发动机功率丢失。

5. The hydraulic system uses constant power variable displacement piston pump to reduce the loss of engine power.

6、行进体系由发动机从变矩器以及前后驱动轴驱动到前后轴。变矩器的运用削减了对发动机的影响并延长了发动机的运用寿命。

6. The propulsion system is driven by the engine from the torque converter and the front and rear drive shafts to the front and rear shafts. The application of torque converter reduces the impact on the engine and extends the service life of the engine.

混凝土搅拌车在运输过程中会始终保持搅拌筒转动，以保证所运载的混凝土不会凝固。运送完混凝土后， 通常都会用水冲洗搅拌筒内部， 防止硬化的混凝土占用空间， 使搅拌筒的容积越来越少。

The concrete mixer truck will always keep the mixing drum rotating during transportation to ensure that the concrete will not solidify. After the concrete is transported, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from occupying the space and reduce the volume of the mixing drum.
