The LDJ400 The LDJ400 series multi-functional tunnel boring machine is a state-of-the-art solution for non-explosive tunnel excavation. Utilizing advanced high-frequency hammers or breaker hammers, it efficiently breaks rocks, while bucket teeth or drill rods wedge into the surrounding rock to leverage gravity for automatic penetration. High-frequency hammers are optimized for rocks below 40MPa, while breaking hammers tackle harder rocks. Featuring local control and wireless remote control, this versatile machine adapts to tunnel dimensions ranging from 6 to 9.5 meters. It excels in high-frequency rock breaking, rapid soft soil excavation, contour trimming, and spray dust removal. Perfect for construction in sensitive areas such as airports, residential zones, and wildlife reserves, this machine minimizes over- and under-excavation and mitigates risks like landslides.
Excavation Efficiency: Boasting a comprehensive excavation efficiency of up to 50m³/h for grade IV and V surrounding rocks;
Minimal Impact on Surrounding Rock: Our non-explosive excavation method ensures minimal disturbance to surrounding rock structures;
Precise Over- and Under-Excavation Control: The machine's movements are precisely controlled, allowing over- and under-excavation control within a remarkable 20 centimeters;
Spray Dust Removal: Equipped with a cutting-edge dust removal spray system, it effectively manages dust, ensuring a safe construction environment;
High-Frequency Rock Breaking: Featuring a patented three-toothed or two-toothed base and a high-frequency breaker hammer, it achieves rapid rock breaking with powerful impact;
Remote Control: All machine movements are remotely controlled, providing ease of operation. Operators can flexibly adjust positions for optimal convenience;
Diesel-Electric Dual Power System: Supporting diesel-powered emergency functions and electric construction, it reduces costs and prevents exhaust pollution and heat buildup in the tunnel;
Efficient Slag Discharge: Certain models come equipped with slag collecting and discharging devices, offering a slag discharge capacity of 180m³/h to meet rapid discharging needs without site departure.
