The HTY300 is a tracked, fully hydraulic integrated screening and backfilling machine specifically designed for backfilling trenches used in oil/natural gas/municipal water supply and drainage/heating pipelines. Positioned for high-flow, high-density, and low-damage backfilling, it features integrated screening, backfilling, and leveling, low ground pressure, pipeline protection, and adaptability to all working conditions. It is the mainstay model for long-distance pipeline projects, narrow trench spaces, and soft soil/wetland backfilling, replacing the traditional combination of manual labor, loaders, and road rollers, resulting in improved efficiency and quality.
· Superior backfilling efficiency and quality: 300m³/h high flow rate + fully automatic screening + layered leveling, 100% compaction compliance rate, one-time forming without secondary compaction, saving 50%+ construction time compared to traditional processes and reducing rework rates.
• Strong pipeline protection capability: Flexible discharge + anti-collision sensors + limit switches ensure zero scratches and zero damage to the pipeline anti-corrosion layer, solving the core pain points of traditional backfilling that "damages pipelines and leaves hidden dangers," thus improving the project qualification rate.
• Strong terrain adaptability: Wetland-type tracks + low ground pressure + on-the-spot turning make it superior to loaders/road rollers in soft soil/wetlands/narrow trenches/mountainous areas, solving the problems of "inability to enter, instability, and incomplete filling."
• Safe and reliable + low operation and maintenance costs: Multiple hydraulic safety features + intelligent monitoring + imported core components result in a low failure rate and an uptime rate of ≥96%; modular design + universal wear parts facilitate convenient maintenance, and the total life cycle cost is 50%+ lower than imported equipment of the same tonnage.
