Q:How to calculate the power of concrete pump motor?
Second, the amount of transport is the amount of export pressure is determined,
Q:What is the washing process of the concrete pump pipe?
Connect the reducing pipe and close the discharge door. Pour water directly into the hopper.
Q:What is the difference between concrete pump and ground pump?
Ground pump only conveying function, the price is cheaper, and now are used to transport mixing machine, the ground pump is a bit uneconomical
