Before starting the mixer track, the operating handle of the mixer drum must be in the "stop" position.
After the mixer starts the engine, rotate the drum at a low speed for about 10 minutes so that the hydraulic oil temperature exceeds 20 ° C before starting operation.
If the mixer truck is parked outside, the mixing drum should be reversed before loading to drain water and debris to ensure the quality of concrete.
When transporting concrete by mixer truck, please ensure that the sliding bucket is in place to avoid loosening, pedestrian injury or swing, which may affect the normal operation of other vehicles. to
当搅拌车装载混合混凝土时，搅拌桶的速度为2-10 rpm。在运输过程中，在平坦路面上搅拌桶的速度保证为2-3 rpm。在超过50的侧坡上行驶和在左右摇摆较大的道路上行驶时，必须在路面状况得到改善后停止混合料灌浆并重新开始混合料灌浆。
When the mixer truck is loading the mixed concrete, the speed of the mixing drum is 2-10 rpm. During transportation, the speed of the mixing drum is guaranteed to be 2-3 rpm on the flat road. When driving on the side slope over 50 and on the road with large left-right swing, the mixture grouting must be stopped and restarted after the road condition is improved.
The time of transporting concrete by concrete mixer truck shall not exceed the time specified by mixing station. During the transportation of concrete, do not stop the mixing bucket for a long time to prevent concrete segregation.
If the mixer truck is equipped with concrete, the dead time on site shall not exceed one hour. If time has passed, field personnel will need to take timely action.
Concrete blocks transported by mixer truck must be at least 8 cm. From the beginning of concrete entering the storage tank to discharging, the discharging time shall not exceed 2 hours in hot weather and 2.5 hours in cold weather.
Before the concrete is ejected by the mixer truck, rotate the mixing drum at a speed of 10-12 rpm for 1 minute, and then eject.
After the concrete mixer drains the truck, immediately flush the inlet, drain funnel and drain trough with the hose attached to the truck to remove dust or residual concrete from the truck body. Pour 150-200l clean water into the mixing bucket. In the process of returning, slowly rotate the mixing drum to clean the inner wall, prevent slag from adhering to the mixing drum wall and mixing blades, add water and refill.
