The secondary structure pump is a concrete conveying equipment specially used for the construction of secondary structures of buildings. It is small in size, flexible in movement, and can easily enter narrow spaces for operation. The pump adopts an advanced hydraulic system with stable pressure, which can achieve high-precision concrete conveying and effectively control the conveying volume. It has wear-resistant conveying pipes and efficient sealing devices, which can ensure that the concrete does not leak or clog during the conveying process, improve construction efficiency, and ensure construction quality. It is widely used in the secondary structure casting of high-rise buildings, such as structural columns, lintels, window sills and other parts, and is an important equipment for improving the efficiency and quality of secondary structure construction in building construction.
