43m Truck-mounted Concrete Pump

1. Powerful Pumping Performance – Excellent Material Adaptability

  • High-pressure pumping system with a maximum outlet pressure of 10 MPa, ensuring strong pumping capacity and excellent adaptability to different concrete mixes.

  • Cylinder swing and reversing capability improved by 40% compared to industry benchmarks, allowing smooth operation even after long waiting times with concrete inside the system.

2. Stable Operation – High Reliability on Site

  • Equipped with active boom vibration damping technology, significantly reducing boom shaking during operation for safer and more stable concrete placing.

  • External boom linkage design achieves effective lightweight construction while maintaining overall structural rigidity and stability.

  • Industry-first open hydraulic system with pressure-based reversing technology, delivering smoother and more reliable pumping direction changes.

3. Energy Saving & Cost Reduction

  • Optimized engine power output curve precisely matched with real construction working conditions to reduce fuel consumption.

  • Intelligent coordination between boom movements and pumping operations across different working scenarios, further improving energy efficiency and lowering operating costs.

4. High-End Customization – Professionally Matched Solutions

  • Product development and configuration guided by a technical team led by top-level industry chief engineers.

  • Supports both superstructure-only and complete vehicle customization, offering multiple optional configurations.

  • OEM and private-label solutions available to meet diverse market and project requirements.

5. Qualified for Global Export – International Certifications

  • Certified under China Compulsory Certification (CCC) standards.

  • Compliant with ISO 9001 International Quality Management System.

  • Fully certified with EU CE conformity, meeting European safety and quality requirements.
