The LDJ400 The LDJ400 series multi-functional tunnel boring machine is a state-of-the-art solution designed for non-explosive tunnel excavation. Engineered for versatility, it employs either a high-frequency hammer or a breaker hammer to effectively fracture rocks. Utilizing bucket teeth or drill rods to wedge into the rock, the machine leverages the gravity of the free face surrounding the rock to facilitate automatic penetration. (High-frequency hammers are ideal for rocks below 40MPa, while breaker hammers are suited for harder rocks.) This advanced equipment offers both local and wireless remote control, accommodating tunnel diameters from 6 to 9.5 meters. Its multifunctional capabilities include high-frequency rock breaking, rapid excavation of soft soil, contour trimming, and spray dust removal, making it an optimal choice for construction in blast-restricted zones such as airports, residential areas, and wildlife reserves. The machine's flexibility ensures it meets the diverse construction needs across various rock types, significantly reducing over- and under-excavation and mitigating risks like landslides.
Achieves comprehensive excavation efficiency for grade IV and V surrounding rocks, reaching up to 50m³/h.
Equipped with a dust removal spray system, this machine effectively controls dust, ensuring a safer construction environment.
Features a patented three-toothed or two-toothed base coupled with a high-frequency breaker hammer for rapid rock breaking and robust impact;
Minimal Disturbance to Surrounding Rock: Employs a non-explosive excavation method, causing minimal disruption to the surrounding rock.
Precise Over- and Under-Excavation Control: Entire machine movements are precisely controlled, with over- and under-excavation of the contour surface maintained within a 20-centimeter tolerance.
Advanced Remote Control: All machine movements are remotely controlled, offering ease of operation. Operators can adjust positions flexibly for enhanced convenience.
Diesel-Electric Dual Power System: Supports diesel-powered emergencies and transmissions alongside electric construction, reducing costs. This system minimizes exhaust gas emissions and heat accumulation in the tunnel during operations.
Efficient Slag Discharge: Certain models feature slag collecting and discharging devices, boasting a discharge capacity of 180m³/h. This meets the rapid slag discharge needs of small-section equipment without requiring site departure.
