The prerequisite for efficient operation: the correct use of automatic loading concrete mixer trucks

The correct use of automatic loading mixer trucks is conducive to the smooth progress of construction and can improve the efficiency of engineering work. If not used correctly, it will damage the mechanical parts of the equipment and reduce its service life. The most important thing when using it is to strictly follow the instructions for use. Generally, if the temperature of the automatic feeding mixer is too high in summer, you should stop it immediately and wait for the temperature to drop before continuing to use it.

1. When operating the self-loading mixer truck, pay attention to the hydraulic system pressure which should comply with the regulations in the instruction manual and should not be adjusted at will. The quality and quantity of hydraulic oil should meet the original requirements.

2. When operating the automatic loading mixer, pay attention to draining the remaining water and debris in the mixing drum before loading. It must be rotated continuously during transportation to prevent concrete from segregating. Before the concrete mixer truck arrives at the construction site and unloads materials, the mixing drum should be rotated at full speed at 14-18 rpm for 1-2 minutes, and then reverse unloading. Before reversing, the mixing drum should be stopped and then reversed.

3. If the ambient temperature is higher than +25 degrees Celsius, the duration from loading, transportation, and unloading shall not exceed 60 minutes. If the ambient temperature is lower than +25 degrees Celsius, the above time shall not exceed 90 minutes.

4. During winter construction, you should do the following: check whether there is ice before starting the machine; carefully remove the residual water in the mixing drum and water supply system after get off work, turn off the water pump switch, and put the control handle in the "stop" position.

5. After unloading materials at the construction site, you should immediately use the hose that comes with the equipment to flush the feed hopper, discharge hopper, discharge chute, etc. to remove the sludge and concrete adhering to various parts of the vehicle body. On the way back to the mixing station, 150-200L of water should be injected into the mixing drum to clean the concrete residue bonded to the drum wall and blades.

6. After work every day, the driver should be responsible for injecting clean water into the mixing barrel of the automatic feeding mixer and rotating it at high speed (14-18 rpm) for 5-10 minutes, and then draining the water to ensure that the inside of the barrel is clean. When cleaning various parts of the mixing drum with high-pressure water, attention should be paid to avoiding parts such as instruments and joysticks. The distance between the pressure water nozzle and the paint surface of the vehicle body shall not be less than 40 cm.
