Audited Supplier The LDJ400 The LDJ400 series multi-functional tunnel boring machine is a specialized marvel engineered for non-explosive tunnel excavation. Equipped with a sophisticated high-frequency hammer or breaker hammer, this machine fractures rocks efficiently. It employs bucket teeth or drill rods to wedge into the surrounding rock, leveraging gravity to naturally break free. High-frequency hammers are optimal for rocks below 40MPa, while breaker hammers tackle harder rocks. Its features include local control and wireless remote control, adaptable for tunnel diameters ranging from 6 to 9.5 meters. This versatile machine combines high-frequency rock breaking, rapid soft soil excavation, precise contour trimming, and effective spray dust removal. Ideal for restricted-blasting areas like airports, residential zones, and wildlife reserves, its flexibility meets various geological conditions, minimizing over-excavation and preventing landslides.
Excavation Efficiency: Remarkable excavation efficiency for grade IV and V rocks, achieving up to 50m³/h.
Minimal Disturbance to Surrounding Rock: The non-explosive excavation method ensures minimal disruption to the surrounding rock.
Precise Control of Over- and Under-Excavation: Advanced control mechanisms allow precise manipulation of the entire machine, maintaining over- and under-excavation within a tight 20-centimeter tolerance.
Spray Dust Removal: Equipped with a comprehensive dust removal spray system, the machine effectively controls dust, ensuring a safer construction environment.
High-Frequency Rock Breaking: Using a patented three-toothed or two-toothed base combined with a high-frequency breaker hammer, this machine achieves rapid rock breaking with powerful impact.
Remote Control: All machine operations are managed remotely, offering unparalleled ease and convenience. Operators can adjust the machine's position flexibly for optimal control.
Diesel-Electric Dual Power System: Supports both diesel-powered emergency operations and electric construction, significantly reducing costs. This system ensures no exhaust gas pollutes the tunnel, and heat accumulation is minimized.
Efficient Slag Discharge: Certain models feature advanced slag collecting and discharging devices, with a capacity of 180m³/h. This innovation ensures rapid slag discharge for small-section equipment without requiring site departure.
