Audited Supplier The LDJ400 The LDJ400 series multi-functional tunnel boring machine is a state-of-the-art, specialized equipment designed for non-explosive tunnel excavation. Utilizing high-frequency hammers or breaker hammers, this machine efficiently breaks rocks by wedging them with bucket teeth or drill rods. Rocks with hardness below 40MPa are easily managed with high-frequency hammers, while breaking hammers tackle harder, less developed rocks. The LDJ400 boasts local control and wireless remote control, accommodating tunnel excavations ranging from 6 to 9.5 meters. Its versatile capabilities include high-frequency rock breaking, swift soft soil excavation, precise contour trimming, and spray dust removal. Ideal for construction in sensitive areas such as airports, residential zones, and wildlife reserves, this machine offers exceptional flexibility, addressing various surrounding rock conditions. It minimizes over- and under-excavation, reducing the risk of landslides and other complications.
Excavation Efficiency: Achieve comprehensive excavation efficiency for grade IV and V surrounding rocks up to 50m³/h.
Minimal Disturbance to Surrounding Rock: Our non-explosive excavation method ensures minimal turbulence to the surrounding rock.
Precise Over- and Under-Excavation Control: The entire machine's movements are meticulously controlled, keeping over- and under-excavations within 20 centimeters of the contour surface.
Effective Spray Dust Removal: Equipped with an advanced dust removal spray system, the LDJ400 maintains a safer construction environment by effectively controlling dust.
High-Frequency Rock Breaking: Utilizes patented three-toothed or two-toothed bases and a high-frequency breaker hammer, ensuring rapid rock breaking speeds and powerful impact.
Convenient Remote Control: Remotely control all movements of the machine, allowing for easy, flexible operation and adjustment of positions for enhanced convenience.
Diesel-Electric Dual Power System: Supports both diesel-powered emergency and transmission functions alongside electric construction, minimizing costs and avoiding tunnel air pollution and heat accumulation.
Efficient Slag Discharge: Features models equipped with slag collecting and discharging devices, capable of a slag discharge capacity of 180m³/h, meeting the rapid slag discharge needs of small-section equipment without site departure.
