Treatment method for non rotation of mixing drum during concrete mixer transportation:

1、混凝土攪拌機運輸過程中有混泥土卡住了；清理干凈就沒有問題了；

1. The concrete is stuck during the transportation of the concrete mixer; Clean up and there will be no problem;

2、混凝土攪拌機液壓系統或發動機故障的處理：

2. Troubleshooting of hydraulic system or engine of concrete mixer:

1）打開攪拌筒檢修孔蓋，旋松馬達上高壓軟管的管接頭，旋轉拌筒使拌筒檢修孔斜向下，將砼從攪拌筒檢修孔排出；

1) Open the manhole cover of the mixing drum, unscrew the pipe joint of the high-pressure hose on the motor, rotate the mixing drum so that the manhole of the mixing drum is inclined downward, and discharge the concrete from the manhole of the mixing drum;

2）將故障車的高壓膠管從馬達上卸下，把救援用的高壓膠管接上，另一端接在救援車的油泵上，并將應急用的回油管一端接在故障車的馬達泄油口，回油管另一端接在救援車的油泵回油口，利用救援車來控制故障車拌筒的旋轉，將砼排出。

2) Remove the high-pressure rubber hose of the failed vehicle from the motor, connect the high-pressure rubber hose for rescue, connect the other end to the oil pump of the rescue vehicle, connect one end of the emergency oil return pipe to the motor drain port of the failed vehicle, and connect the other end of the oil return pipe to the oil return port of the oil pump of the rescue vehicle. Use the rescue vehicle to control the rotation of the mixing drum of the failed vehicle and discharge the concrete.

3、混凝土攪拌機馬達發生故障，處理則較簡單，可把救援車的馬達卸下裝在故障車上，再將各個油管接好，啟動救援車即可將拌筒內的砼排出。

3. If the motor of the concrete mixer fails, the treatment is relatively simple. The motor of the rescue vehicle can be unloaded and installed on the failed vehicle, and then each oil pipe can be connected, and the concrete in the mixing drum can be discharged by starting the rescue vehicle.
