The concrete pumping machine for sale is a kind of mechanical equipment commonly used in construction at present. In daily life, the concrete pump machine must be operated according to the usage specifications. It can greatly reduce the occurrence of hidden dangers in the construction process. So what should be paid attention to in the safe operation of concrete pumping machine? Specifically, it should be carried out from the following points.

 
1, Placement specification
When the concrete pumping machine for sale is stagnant, it should be noted that the location is flat and solid, there are no obstacles around, and there is no high-voltage power line above. In addition, the concrete pump machine should not be parked on the slope, level and stability; at the same time, the concrete pump should turn on the stop light to avoid collision.
2, Pumping rules
Before the concrete pumping machine is pumped, if the temperature of the hydraulic oil is lower than 15 degrees Celsius, the method of prolonging the idle running time should be used to increase the oil temperature. During the pumping process, attention should be paid to check the operation of the concrete pump machine and the stirring device, monitor the instruments and indicator lights, and if any abnormality is found, it should be stopped in time.
3, Hopper processing
The concrete surface in the hopper of the concrete pump should be kept above the centerline of the mixing shaft. The grid on the hopper cannot be removed during the operation, and the unqualified aggregate or debris should be removed in time; if the pressure gauge rises to the highest value during pumping and the running sound changes, the pumping should be stopped immediately and Use the reverse operation method to remove pipe blockage; if this process is ineffective, the pipe should be disassembled for cleaning.
4. After working processing
After the operation, all the concrete in the pipes and hoppers of concrete pumping machine for sale should be output, and the hoppers and pipes should be flushed at the same time. The operation switches, adjustment handles, handwheels, control rods, cocks, etc. of all parts should be reset, and the hydraulic system should be unloaded. And retract the outriggers, park the concrete pump in a safe area, and drain the water in winter.
