The small secondary structure pump is a concrete delivery device specifically designed for secondary structure construction in buildings. It has a compact size and flexible mobility, allowing it to easily access narrow spaces for operation. This pump utilizes an advanced hydraulic system with stable pressure, enabling high-precision concrete delivery and effective control of the delivery volume. It features wear-resistant delivery 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, window sills, and other areas, making it an important device for enhancing the efficiency and quality of secondary structure construction in building projects.
