Audited Supplier The LDJ400 The LDJ400 series multi-functional tunnel boring machine is an advanced, non-explosive tunnel excavation marvel. It employs a high-frequency hammer or breaker hammer to expertly fracture rocks, using bucket teeth or drill rods to wedge and break through surrounding rock via gravity, ensuring seamless excavation. Perfect for rocks below 40MPa with high-frequency hammers and tougher rocks with breaker hammers, this equipment integrates local and wireless remote control, making it adaptable for tunnels ranging from 6 to 9.5 meters. Offering rock breaking, soft soil excavation, contour trimming, and spray dust removal, this versatile machine is ideal for restricted blasting zones like airports, residential areas, and wildlife reserves. It flexibly meets various construction requirements, minimizing over- and under-excavation and preventing landslides.
Excavation Efficiency: Offers comprehensive excavation efficiency for grade IV and V surrounding rocks up to an impressive 50m³/h.
Minimal Disturbance to Surrounding Rock: Adopts a non-explosive excavation method, ensuring minimal disturbance to the surrounding rock structure.
Precise Control Over Excavation: Accurately manages machine movements, maintaining over- and under-excavation within a precise 20-centimeter margin.
Effective Dust Control: Equipped with a comprehensive dust removal spray system, significantly enhancing the safety and cleanliness of the construction environment.
High-Frequency Rock Breaking: Utilizes a patented three-toothed or two-toothed base with a high-frequency breaker hammer, ensuring rapid and forceful rock breaking.
Remote Operation: Fully remote-controlled operations enhance convenience and flexibility, allowing operators to adjust positions seamlessly.
Dual Power System: Features a diesel-electric dual power system for emergency and everyday operations, reducing costs and minimizing exhaust emissions and heat accumulation in the tunnel.
Efficient Slag Discharge: Certain models include slag collecting and discharging devices, boasting a slag discharge capacity of 180m³/h to meet the rapid slag removal needs of small sections without leaving the site.
