Audited Supplier The LDJ400 Introducing the LDJ400 series multi-functional tunnel boring machine, a premier solution for non-explosive tunnel excavation! This cutting-edge equipment employs a high-frequency hammer or breaker hammer to efficiently fracture rocks. Utilizing bucket teeth or drill rods, it wedges and leverages the surrounding rock's natural gravity, enabling seamless breakthroughs. Perfect for rocks with varying hardness, the high-frequency hammers tackle rocks up to 40MPa, while breaker hammers handle tougher rocks. The LDJ400 boasts dual control options—local and wireless remote—making it versatile for tunnels spanning 6 to 9.5 meters. Its multifunctionality includes high-frequency rock breaking, rapid soft soil excavation, precise contour trimming, and effective dust suppression. Ideal for construction sites where blasting is restricted (airports, residential areas, wildlife reserves), this machine ensures flexibility, reduces over- and under-excavation, and mitigates landslide risks.
Excavation Efficiency: Achieve unmatched excavation efficiency with rates up to 50m³/h for grade IV and V surrounding rocks.
Minimal Disturbance to Surrounding Rock: Employ a non-explosive excavation method that causes minimal disturbance to the surrounding rock.
Precise Over- and Under-Excavation Control: Experience precision in movement with control over contour surface excavation within 20 centimeters.
Spray Dust Removal: Equipped with an effective dust removal spray system, ensuring a safe and clean construction environment.
High-Frequency Rock Breaking: Utilize patented three-toothed or two-toothed bases along with a high-frequency breaker hammer for rapid, impactful rock breaking.
Remote Control: Operate with ease and flexibility via remote control, allowing convenient adjustment of the machine's position.
Diesel-Electric Dual Power System: Benefit from both diesel-powered emergency transmission and electric construction, reducing costs and preventing exhaust gas pollution in the tunnel. Heat accumulation is minimized during operations.
Efficient Slag Discharge: Certain models feature slag collecting and discharging devices with an impressive capacity of 180m³/h, facilitating rapid slag removal for small-section equipment without site contamination.
