　　Concrete pump is a construction equipment that relies on pressure to convey concrete through pipelines.It is equipped with special pipelines,which can continuously complete horizontal and vertical transportation of concrete along the pipeline.It is an ideal type of existing concrete conveying equipment.

　　Combining the production of ready-mixed concrete with pumping construction,and using the concrete mixer truck for intermediate operation,the continuous pumping and pouring of concrete can be realized.Concrete conveying work for large-scale concrete projects.

　　The concrete floor pump is flexible,and the higher the boom height,the larger the pouring height and the distribution radius,and the stronger the construction adaptability.The high-boom concrete pump truck should be used as much as possible in the construction.The delivery pump truck with the boom length of 46~66m is a large-scale product in the market,accounting for about 75%.
