    The history of the development of concrete pumps takes you to understand the changes in China
    Our country China began to explore the development of concrete pumps in the 1970s and introduced technology to manufacture concrete pumps in the 1980s, but the real domestic concrete pump manufacturing began. After more than 20 years of development, China has become the world's largest producer of concrete pumps. In 2007, about 3,000 pump trucks were sold, and about 6,500 trailer pumps were sold. In the same period, the total output of foreign concrete pumps was only about 12,000 units.

    Basic working principle of concrete pump
    Most of the small concrete pumps are in the form of double cylinders. Its two hydraulic cylinders drive the two conveying cylinder pistons to work alternately, which not only makes the conveying of concrete more stable and continuous, but also greatly increases the displacement. Its working principle varies according to the distribution valve and control mode, but the main difference is still reflected in the realization of the reversing action.
