Concrete pumps are the main concrete pumping equipment in building construction. We need to be familiar with the operation of the equipment. If the operation is not correct, the concrete pump will be abnormal, so the operator should pay attention to the operation requirements of the concrete pump.

　　 There are two types of equipment for concrete pumps, fine stone and large particles. According to the requirements of the equipment, attention should be paid to the particle size of the pumped sand and gravel.

　　Before use, check the fastening of each bolt of the equipment, as well as the fastening and sealing at the interface of the conveying pipe. When the concrete pump is under pressure, do not open any conveying pipes and hydraulic pipes, nor adjust the safety valve at will.

　　 During the pumping process, attention should be paid to checking the instrument and indicator lights of the equipment. If abnormalities occur, adjustments should be made in time. If the delivery pump is blocked, the pump can be reversed to return the concrete in the delivery pipe to the hopper, and then normal pumping can be done.

　　After use, all the concrete in the hopper and conveying pipe should be discharged, and then the hopper and conveying pipe should be cleaned with water, so as to prevent the residual concrete from being hard to clean after solidification and affecting the next use.
