The LDJ400 The LDJ400 series multi-functional tunnel boring machine is a revolutionary piece of equipment designed specifically for non-explosive tunnel excavation. Equipped with cutting-edge technology, it employs a high-frequency hammer or breaker hammer to efficiently break rocks. The bucket teeth or drill rods wedge into the surrounding rock, leveraging the gravity of the free face to automatically break through. High-frequency hammers are ideal for rocks below 40MPa, while breaker hammers tackle harder rocks. This machine features both local and wireless remote control, making it adaptable for tunnel excavation projects ranging from 6 to 9.5 meters. It excels in high-frequency rock breaking, rapid excavation of soft soil, precise contour trimming, and effective spray dust removal. Ideal for areas where blasting is restricted, such as airports, residential zones, and wildlife reserves, the LDJ400 is highly flexible, minimizing over- and under-excavation and preventing landslides and other construction hazards.
Excavation Efficiency: The comprehensive excavation efficiency for grade IV and V surrounding rocks reaches an impressive 50m³/h.
Minimal Disturbance to Surrounding Rock: This non-explosive excavation method ensures minimal disturbance to the surrounding rock.
Precise Over- and Under-Excavation Control: Our machine’s movements are meticulously controlled, with over- and under-excavation precision within 20 centimeters.
Spray Dust Removal: Equipped with an advanced dust removal spray system, the machine effectively controls dust, ensuring a safer construction environment.
High-Frequency Rock Breaking: Our patented high-frequency breaker hammer, with either a three-toothed or two-toothed base, achieves rapid rock breaking and strong impact.
Remote Control: All machine movements are remotely controlled, making operation easy and convenient. The operator can flexibly adjust the position for optimal control.
Diesel-Electric Dual Power System: Supporting both diesel-powered emergency and electric construction, this system minimizes construction costs, ensures no exhaust gas pollution, and keeps heat accumulation minimal during operations.
Efficient Slag Discharge: Select models feature slag collecting and discharging devices, boasting a discharge capacity of 180m³/h, perfectly meeting the needs of small-section equipment for rapid slag removal without site departure.
