The LDJ400 The LDJ400 series multi-functional tunnel boring machine is a specialized piece of equipment designed for non-explosive tunnel excavation. Utilizing advanced high-frequency hammers or breaker hammers, it efficiently breaks through rocks. The equipment features local and wireless remote controls, adapting seamlessly to tunnel excavations ranging from 6 to 9.5 meters. Its impressive capabilities include high-frequency rock breaking, rapid excavation of soft soil, precision contour trimming, and effective dust removal via spray systems. Ideal for use in construction zones where blasting is restricted, such as airports, residential areas, and wildlife reserves, the LDJ400 is highly versatile, accommodating various types of surrounding rocks while mitigating over- and under-excavation, thereby preventing landslides and other issues.
Excavation Efficiency: Achieves comprehensive excavation efficiency for grade IV and V surrounding rocks, reaching up to 50m³/h.
Minimal Disturbance to Surrounding Rocks: The non-explosive excavation method ensures minimal disruption to the surrounding rock.
Precise Over- and Under-Excavation Control: Accurately controls machine movements, maintaining over- and under-excavation of the contour surface within 20 centimeters.
Spray Dust Removal: Equipped with a dust removal spray system to effectively control dust, ensuring a safe construction environment.
High-Frequency Rock Breaking: Features patented three-toothed or two-toothed bases and a high-frequency breaker hammer for rapid rock breaking and strong impact.
Remote Control: All machine movements are controlled remotely, enhancing operational ease and flexibility for the operator.
Diesel-Electric Dual Power System: Supports diesel-powered emergency and transmission, alongside electric construction, reducing costs and minimizing tunnel exhaust and heat accumulation.
Efficient Slag Discharge: Certain models feature slag collecting and discharging devices, with a discharge capacity of up to 180m³/h, meeting the rapid slag discharge needs of small-section equipment without site departure.
