The secondary structure pump is a concrete conveying device specifically designed for the construction of secondary structures in buildings. It is compact, mobile, and can easily operate in narrow spaces. This pump uses an advanced hydraulic system with stable pressure, enabling high-precision concrete delivery and effective control of the delivery volume. It features wear-resistant conveying pipes and efficient sealing devices, ensuring that concrete does not leak or clog during the delivery process, thus improving construction efficiency and ensuring construction quality. It is widely used in the secondary structure pouring of high-rise buildings, such as structural columns, beams, and window sills, making it an important device for enhancing the efficiency and quality of secondary structure construction in building projects.
