Audited Supplier The LDJ400 The LDJ400 series multi-functional tunnel boring machine is a specialized piece of equipment designed for non-explosive tunnel excavation. It employs a high-frequency hammer or breaker hammer to fragment rocks. The machine uses bucket teeth or drill rods to wedge the surrounding rock, allowing the gravity of the free face to naturally break it through. High-frequency hammers are ideal for rocks below 40MPa, while breaking hammers are used for harder and poorly developed rocks. This advanced equipment features local control and wireless remote control, adaptable for tunnel excavations ranging from 6 to 9.5 meters. Its multifunctional capabilities include high-frequency rock breaking, rapid soft soil excavation, contour trimming, and spray dust removal. These features make it exceptionally suitable for construction in areas with blasting restrictions, such as airports, residential areas, and wildlife reserves. The machine's flexibility enables it to handle various types of surrounding rocks, minimizing over- and under-excavation, and preventing landslides and other complications.
Excavation Efficiency: Achieves an impressive comprehensive excavation efficiency of up to 50m³/h for grade IV and V surrounding rocks.
Minimal Disturbance to Surrounding Rock: The non-explosive excavation method ensures minimal disturbance to the surrounding rock.
Precise Over- and Under-Excavation Control: Entire machine movements are precisely controlled, keeping over- and under-excavation of the contour surface 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: Utilizes a patented three-toothed or two-toothed base combined with a high-frequency breaker hammer, achieving fast rock breaking speeds and strong impact.
Remote Control: All machine movements are remotely controlled, making operation easy and convenient. The operator can flexibly adjust positions for optimal operation.
Diesel-Electric Dual Power System: Supports diesel-powered emergency and transmission along with electric construction, minimizing costs and avoiding exhaust pollution in the tunnel. Heat accumulation is kept to minimal levels during construction.
Efficient Slag Discharge: Certain models come equipped with slag collecting and discharging devices, boasting a slag discharge capacity of 180m³/h. This meets the rapid slag discharging needs of small-section equipment without leaving the site.
