Concrete mixer maintenance tips
1. Before starting the mixer truck, the mixer drum operating handle should be placed in the "stop" position.
2. After the mixer truck starts the engine, the mixer drum should be rotated at low speed for about 10 minutes, and the hydraulic oil temperature should rise above 20°C before it can work.
3. When the mixer truck is parked in the open air, the mixing drum should be reversed before charging to discharge the accumulated water and sundries to ensure the quality of the concrete.
4. When the mixer truck is transporting concrete, it is necessary to ensure that the sliding bucket is placed firmly to prevent swinging due to loosening, injuring pedestrians or affecting the normal operation of other vehicles.
5. When the mixer truck transports the mixed concrete, the speed of the mixing drum is 210 rpm. During the transportation process, the speed of the mixing drum on the flat road is guaranteed to be 2-3 rpm. When driving on the road with a roll slope greater than 50, When the road surface is shaken from side to side, the stirring and rotation should be stopped, and the stirring and rotation should be resumed after the road conditions improve.
6. After the work of the cement mixer truck is completed, the inside of the mixing drum and the body should be cleaned, and the remaining concrete should not be left in the drum.
7. When the water pump is working, the cement mixer truck is prohibited from idling, and it should not be used for more than 15 minutes continuously.
