搅拌车是一种特殊的车辆，并非所有会开车的司机都会开搅拌车。如果操作不当，会导致卡车翻车，液压泵、电机、减速器等部件磨损过快，甚会造成严重后果。所以小型搅拌车操作之前建议看懂说明事项才能顺利施工。

Mixer truck is a special vehicle. Not all drivers who can drive can drive a mixer truck. If the operation is improper, the truck will overturn, and the hydraulic pump, motor, reducer and other components will wear too fast, and even cause serious consequences. Therefore, it is recommended to understand the instructions before the operation of small mixer truck in order to carry out the construction smoothly.

1、搅拌车启动前，应将搅拌筒操作手柄置于“停止”位置。

1. Before starting the mixer truck, put the operating handle of the mixing drum in the "stop" position.

2、搅拌车启动发动机后，应低速转动搅拌筒10分钟左右，液压油温度升20℃以上方可工作。

2. After starting the engine of the mixer truck, rotate the mixing drum at low speed for about 10 minutes, and the hydraulic oil can work when the temperature rises above 20 ℃.

3、搅拌车露天停放时，加料前应倒转搅拌筒，排出积水和杂物，保证混凝土质量。

3. When the mixer truck is parked in the open air, the mixing drum shall be reversed before charging to discharge ponding and sundries to ensure the quality of concrete.

4、搅拌车在运输混凝土时，必须保证滑斗放置牢固，以防在行驶过程中因松动而晃动，伤及行人或影响其他车辆的正常运行。

4. When transporting concrete, the mixer must ensure that the sliding bucket is firmly placed to prevent it from shaking due to looseness during driving, hurting pedestrians or affecting the normal operation of other vehicles.

5、小型搅拌车运输搅拌好的混凝土时，搅拌筒转速为2-10转/分。在运输过程中，保证平路上的搅拌筒转速为2-3转。当路面或左右晃动较大的路面时，应停止搅拌转动，待路况改善后再恢复搅拌转动。

5. When transporting the mixed concrete with a small mixer, the speed of the mixing drum is 2-10 R / min. During transportation, ensure that the rotating speed of the mixing drum on the flat road is 2-3 revolutions. When the road surface or the road surface with large shaking left and right, stop the mixing and rotation, and resume the mixing and rotation after the road condition is improved.

6、搅拌车运输混凝土的时间不能超过搅拌站规定的时间。混凝土输送过程中，搅拌筒不得长时间停机，防止混凝土离析。司机应不时观察具体情况，发现异常及时向调度室报告，并申请处理。

6. The time of concrete transportation by mixer truck shall not exceed the time specified by the mixing plant. During concrete transportation, the mixing drum shall not be shut down for a long time to prevent concrete segregation. The driver shall observe the specific situation from time to time, report any abnormality to the dispatching room in time and apply for handling.

7、搅拌车装载混凝土时，现场停留时间不得超过1小时。逾期的，应当要求现场负责人及时处理。

7. When the mixer truck is loading concrete, the stay time on site shall not exceed 1 hour. If it is overdue, the person in charge of the site shall be required to deal with it in time.

8、搅拌车输送的混凝土坍落度不得小于8cm。混凝土从入罐到卸出，高温时不得超过2小时，阴雨天气低温时不得超过2.5小时。

8. The slump of concrete transported by mixer truck shall not be less than 8cm. The concrete shall not exceed 2 hours at high temperature and 2.5 hours at low temperature in cloudy and rainy weather.

9、搅拌车卸出混凝土前，应使搅拌筒以10-12转/分的速度转动1分钟，方可卸出。

9. Before unloading the concrete from the mixer truck, the mixing drum shall be rotated at the speed of 10-12 rpm for 1 minute before unloading.

10、小型搅拌车卸料完毕后，立即用随车附带的软管排水，清洗进料口、卸料斗和卸料槽，粘在车身上的污垢和残留混凝土。用150-200L的清水填充搅拌桶。回程时，让搅拌筒慢速转动，清洗内壁，防止残留物料粘附在筒壁和搅拌叶片上。在再次充电之前将水放入水中。

10. After the unloading of the small mixer truck, drain the water immediately with the hose attached to the truck, clean the feed inlet, discharge hopper and discharge tank, and remove the dirt and residual concrete adhered to the vehicle body. Fill the mixing drum with 150-200l of clean water. When returning, let the mixing drum rotate slowly and clean the inner wall to prevent residual materials from adhering to the drum wall and mixing blades. Put the water into the water before recharging.
