China Best Selling Trailer Mounted Concrete Pump for Construction Project
Concrete trailer pump is a kind of concrete pumping equipment used to pump mixed liquid concrete to the construction site. Usually, the position of the drag pump needs to be fixed before construction, and the pipeline should be laid in advance.According to the pumping capacity, it can be divided into 30 pumps, 40 pumps, 60 pumps, 80 pumps, 90 pumps, etc. As the name suggests, it pumps 30-90 cubic meters per hour. Among them, the small mini drag pumps 30 pumps and 40 pumps are more suitable for small and medium-sized projects such as rural housing construction.
