The LDJ400 Model Introducing the LDJ400 series multi-functional tunnel boring machine, a cutting-edge solution designed for non-explosive tunnel excavation. This state-of-the-art equipment primarily utilizes a high-frequency hammer or breaker hammer to fracture rocks. Employing bucket teeth or drill rods, it wedges rocks within the surrounding formation, leveraging gravity to automatically break through even the toughest materials. High-frequency hammers are optimal for rocks under 40MPa, while breaker hammers tackle harder, poorly developed rocks. Featuring both local and wireless remote control, the LDJ400 adapts seamlessly to tunnel excavations ranging from 6 to 9.5 meters. This versatile machine excels in high-frequency rock breaking, swift excavation of soft soils, precise contour trimming, and effective spray dust removal. Ideal for construction zones with blasting restrictions like airports, residential areas, and wildlife reserves, its flexibility addresses diverse surrounding rock conditions, minimizing over-excavation, reducing under-excavation, and preventing landslides.
Comprehensive excavation efficiency for grade IV and V surrounding rocks up to 50m³/h;The entire machine is equipped with dust removal spray system to effectively control dust and ensure a safe construction environment;Patented three-toothed base or two -toothed base and a high-frequency breaker hammer to achieve fast rock breaking speed and strong impact;
Slight turbulence to surrounding rock: Non-explosive excavation method causes little disturbance to surrounding rock;
Precise over- and under-excavation control: The movement of the entire machine is accurately controlled, with over- and under-excavation of the contour surface controllable to within 20 centimeters;
Remote control: All movements of the entire machine are controlled remotely, making it easy and convenient to operate. The operator can flexibly adjust the position for more convenient operation;
Diesel-electric dual power system: Diesel-powered emergency and transmission, and electric construction are supported, minimizing construction costs; no exhaust gas pollutes the air in the tunnel and heat accumulation is kept to a minimal level during construction;
Slag discharge efficient : Some models are equipped with slag collecting and slag discharging devices, with a slag discharge capacity of 180m³/h, which can meet the needs of small-section equipment for rapid slag discharging without leaving the site.
