Concrete pump, also known as a concrete pumping unit, consists of a pump body and conveying pipeline. It is a mechanical device that uses pressure to continuously convey concrete through pipelines, primarily used in building construction, bridge, and tunnel projects. It is mainly categorized into gate valve concrete pumps and S-valve concrete pumps. Another type involves mounting the pump body on a truck chassis and equipping it with an extendable or telescopic boom, forming a pump truck.
