Many friends may know that the trailer pump concrete is used for pumping concrete effectively. But do you know to to use it correctly? Do you know how to dear with the fault while working? If you do not know, I am so pleased to tell you about it. Before pumping concrete, pumping water for lubricate the pipeline, check whether the pipe is sealed, whether there is water leakage, and then pumping mortar through the pipeline. After ensure the mortar has open the pipeline, stirred the remaining concrete fully and then pump normally. When start or stop pumping concrete, should contact with the front-end operator in order to avoid accidents.
