1. Check the fuel, lubricating oil, hydraulic oil, brake fluid, cooling water, etc. before the concrete mixing and transportation to ensure sufficient, the quality should meet the requirements.
2. The power output device should be checked and no loose bolts and oil leakage of the bearings should be confirmed.
3. When mixing and transporting, the loading capacity of concrete shall not exceed the rated capacity.
4. Before starting the mixer, place the mixer handle in the “stop” position. After starting the engine, the mixing drum should be rotated at low speed for about 10 minutes to allow the hydraulic oil temperature to rise above 20 °C to work.
5. Before mixing the conveyor truck, the mixing drum should be reversed to drain the water and debris in the cylinder to ensure the quality of the concrete.
6. When loading, the joystick should be placed in the “loading” position, and the speed of the mixing drum should be adjusted to make the feeding smooth.
7. When transporting concrete, ensure that the bucket is placed firmly to prevent swinging due to looseness, injuring pedestrians during travel or affecting the normal operation of other vehicles.
8. When the mixed concrete is shipped, the speed of the mixing drum is 2-10 rpm. During the transportation process, the coagulation is prevented from segregating and the quality is guaranteed. The speed of the mixing drum on the flat road is guaranteed to be 2-3 rpm. When the slope of the slope is greater than 15 degrees, or when the road surface is shaken to the left or right, the agitation rotation should be stopped. After the road condition is improved, the agitation rotation is resumed.
