1. Prepare the emergency drive hose, turn off the faulty commercial concrete cement mixer truck, and remove the high-pressure oil pipe connector on the hydraulic motor.
2. Turn off the rescue vehicle, remove the high-pressure oil pipe of its hydraulic motor, and connect it with the corresponding connector on the faulty vehicle with emergency drive hose.
3. Start the rescue vehicle, turn its control handle to the discharge position, and the commercial concrete in the faulty vehicle will be discharged.
4. After the emergency drive, remove the drive hose and restore the two vehicles to their original state.
1. If it is difficult to implement one method, the following methods must be used to discharge the commercial concrete immediately.
2. Put a wooden wedge between the supporting wheel and the raceway to control the rotation of the mixing drum. Be sure to pay attention to safety; Turn off the engine, remove a high-pressure oil pipe of the hydraulic motor, the mixing drum can rotate freely, control the rotation of the mixing drum, turn the maintenance hole to the lower part, and then open the maintenance hole to clean out the commercial concrete in the drum. At this time, attention must be paid to safety. After the commercial concrete is discharged, the commercial concrete cement mixer truck shall be restored to its original state.
Method 3: break the set concrete with an "air cannon" and shovel it out a little bit.
A opening shall be cut at the lower part of the tank body, and a cover tightened with rose shall be opened. This cover is used to turn on the air and discharge materials in case of emergency. In the process of tank beating, people should ventilate in the tank and put a fan at the inlet of the charging tank to blow in. When the "air cannon" works, it will cause dust and connect a water pipe to wet the broken concrete. After the concrete in the tank is broken and shoveled out, the cut part shall be welded, the upper cover shall be sealed, the water shall be filled to test whether the rotation is normal, and then a small amount of loading shall be increased to see whether the hydraulic press works normally. If everything is normal, it can continue to operate.
Every driver of cement mixer truck should be able to clean the commercial concrete in the cement mixer truck urgently. When the cement mixer truck breaks down, clean it in time to reduce the loss.
