Application:
1. convey fine aggregate concrete and mortar for high buildings.
2. grout heat-insulated lightweight foamed cement, mortar floor heating, and self leveling for ground architecture.
3. spray plain concrete and fiber concrete in engineering construction.
4. convey and spray refractory and thermal insulation material.
5. spray afforestation soil in ecological environment construction.
6. pressure perfussion for foundation piles, backfill in overbroken tunnels, railway slope supporting, and disaster management.

Concrete pumping machine is a machine that uses pressure to continuously transport concrete along pipelines. Composed of pump body and delivery pipe.
According to the structure, it is divided into piston type, extrusion type and hydraulic diaphragm type.
The pump body is installed on the chassis of the car, and then equipped with a retractable or flexural spreader boom to form a pump truck.

Advantages:
1. convey fine aggregate concrete and mortar for high buildings.
2. grout heat-insulated lightweight foamed cement, mortar floor heating, and self leveling for ground architecture.
3. spray plain concrete and fiber concrete in engineering construction.
4. convey and spray refractory and thermal insulation material.
5. spray afforestation soil in ecological environment construction.
