Efficiency: The old concrete mixer trucks Howo 371's mixing system and concrete delivery unit are designed to achieve a high degree of uniform concrete mixing, ensuring the best quality for each discharge. In addition, the discharge speed is fast and the residual rate is extremely low, which greatly improves the working efficiency of old concrete mixer trucks Howo 371d, thus reducing the operating cost and construction period. This makes the old concrete mixer trucks Howo 371 extremely efficient and profitable on the construction site.
1. Preparation before loading
Before loading concrete in the old Howo 371 concrete mixers truck, you first need to make sure that there is no residual moisture or debris in the mixer. The mixing drum should be thoroughly cleaned and its inner wall checked to see if it is clean and free of foreign matter. This is to avoid debris entering the tank of the old Howo 371 concrete mixers truck, affecting the quality of concrete and mixing effect.
2. Mixing requirements during transportation
In order to ensure the uniformity of concrete and avoid the separation of cement and aggregate during concrete transportation, the old Howo 371 concrete mixers truck should be kept in constant rotation. The speed range of the old Howo 371 concrete mixers truck is 14-18 revolutions per minute, ensuring that the concrete is fully mixed throughout the transportation process. Especially in the transportation process, the operation status of the old Howo 371 concrete mixers truck should be checked regularly to ensure its normal operation.
3. Operation process before unloading
When the old Howo 371 concrete mixers truck arrives at the construction site and is ready to unload, the mixing drum should first be run at the normal speed (14-18 RPM) for 1 to 2 minutes to evenly mix the inside of the concrete. After confirming that the stirring drum of the old Howo 371 concrete mixers truck is turning smoothly, the reverse unloading operation can be carried out. At the same time, before unloading, the mixing drum of the old Howo 371 concrete mixers truck must be stopped without any rotation.
4. Influence of ambient temperature on concrete transportation time
Temperature has a significant effect on the working time of concrete. At temperatures above 25 degrees Celsius, the total time from loading to unloading should not exceed 60 minutes to avoid premature solidification of concrete in the old Howo 371 concrete mixers truck tank. If the ambient temperature is below 25 degrees Celsius, it can be appropriately extended, and the transportation time can be extended to 90 minutes. Too high or too low a temperature can affect the flow and strength of the concrete in the old Howo 371 concrete mixers truck tank.
5. Cleaning and maintenance
The old Howo 12 wheeler concrete mixer trucks must be cleaned immediately after unloading at the construction site. Use the hoses carried with the old Howo 12 wheeler concrete mixer trucks to flush the inlet hopper, outlet hopper, discharge chute, etc., to remove the sludge and concrete residue attached to the vehicle body in time. This can effectively prevent the concrete from solidifying on the body of the old Howo 12 wheeler concrete mixer trucks, which will affect the subsequent work.
In addition, on the way back to the mixing plant, 150-200 liters of water should be injected into the mixing tank of the old Howo 12 wheeler concrete mixer trucks for another cleaning. This not only helps remove residual concrete, but also effectively cleans the inner walls and blades of the old Howo 12 wheeler concrete mixer trucks. Prevent the hardening of concrete residue, reduce the difficulty of cleaning, and extend the service life of the tank of old Howo 12 wheeler concrete mixer trucks.
