The XCMG HB43K Truck Mounted Concrete Pump is a high-performance concrete pumping solution developed by XCMG based on advanced technology from SCHWING Germany. Designed for medium and large-scale construction projects, the HB43K combines strong pumping capacity, reliable operation, and flexible mobility to meet the demands of modern concrete construction.
Equipped with a durable Sinotruk chassis and a powerful diesel engine, the HB43K delivers excellent driving performance, high torque output, and strong adaptability on different job sites. The machine adopts an advanced pumping system with Rock Valve technology, full hydraulic reversing, and optimized hydraulic control, ensuring smooth concrete delivery, fast response, and reduced component wear for longer service life.
The HB43K features a five-section Z-type boom design, providing excellent flexibility and a wider working range. With a maximum reach height of 43 meters, a theoretical pumping capacity of 170 m³/h, and a pumping pressure of 8 MPa, it is capable of efficiently handling continuous concrete pouring operations.
The high-rigidity stabilizer structure, intelligent control system, and reliable hydraulic technology improve overall safety, stability, and operating efficiency. The HB43K is widely used in high-rise buildings, bridges, tunnels, commercial construction, and infrastructure projects, making it an ideal choice for contractors seeking a durable and efficient concrete pumping machine.
