Q: What is the lubrication of the concrete pump before it is transported to the concrete?: the first use of water, while wetting the pipe can also be wet template, to moderate

Q: Why concrete pump truck with foreign chassis: China began in 1982 from the introduction of Japanese technology for concrete pump truck production, after 20 years of development, although the current domestic concrete pump design and manufacturing capacity has been greatly improved.

Q: What measures should be taken in the construction of the underground garage: The overall load should be considered, and the load distribution can be optimized by increasing the way of laying the subrack box, less reinforcement and strength of the roof, and reduce the cost

Q: What kind of driver's license does the concrete pump need?: Driver's license to use B2 card, qualification certificate can be transported with ordinary goods, no need to use special vehicle qualification certificate.

Q: What is the cause of concrete pump blockage?: When the above two methods can not rule out the plug, the concrete pump can be removed after the removal of the plugging parts of the pipe, discharge concrete blockage, and then take over the pump.

Q: How to wash the concrete pump with a ball: First in the pump tubing in the concrete residue washed 1-2 side, then put the ball into the feed port, add water to open the pump, the pump will be with the water through the pipeline, the pipe wall

Q: How is the mortar in concrete pumping concrete coexisting and distinguishing in a pump?: When the pump starts to press the concrete, the speed should be slow, when the concrete is sent to the end of the pipe, the speed can be gradually accelerated, and transferred to the normal degree of pumping.

Q: What factors will be taken into account when selecting the pump chassis?: As the pump work strength, for the chassis durability and intact rate requirements are very high, once the chassis failure, brought about not only the maintenance costs, the user's economic benefits will be seriously affected;

Q: How the calculation of the discharge speed of concrete pump truck: the first speed is not a fixed number, the speed depends mainly on the speed of the pump remote control displacement,

Q: What are the precautions for the operation of the concrete pump truck?: After pumping the water, use one of the following methods to lubricate the above parts: Pumping the slurry; pumping 1: 2 cement mortar; pumping the other ingredients in addition to the coarse aggregate and the ratio of the cement mortar.
