Product Description

Product Description

The LDJ400 The LDJ400 series multi-functional tunnel boring machine is an innovative, non-explosive solution designed for efficient tunnel excavation. This state-of-the-art equipment utilizes either a high-frequency hammer or breaker hammer to fracture rocks. Bucket teeth or drill rods wedge the rock in the surrounding formation, and the natural force of gravity facilitates the breaking process. High-frequency hammers are optimal for rocks with a hardness below 40MPa, while breaker hammers are ideal for more robust, less-developed rocks. Featuring both local and wireless remote control, this versatile machine is suitable for tunnels ranging from 6 to 9.5 meters in diameter. Its multifunctionality includes high-frequency rock breaking, rapid excavation of soft soils, precise contour trimming, and advanced spray dust removal. Designed for construction environments with blasting restrictions—such as airports, residential areas, and wildlife reserves—the LDJ400 is highly adaptable, capable of handling various rock types, minimizing over- and under-excavation, and preventing landslides and other complications.

Excavation Efficiency: Achieves comprehensive excavation efficiency for grade IV and V surrounding rocks, reaching up to 50m³/h.

Minimal Disturbance: Employs a non-explosive excavation method that minimizes disturbance to the surrounding rock.

Precise Control: Offers precise control over the entire machine's movements, maintaining over- and under-excavation within 20 centimeters of the contour surface.

Advanced Dust Control: Equipped with a comprehensive dust removal spray system, ensuring effective dust control and a safe construction environment.

High-Frequency Rock Breaking: Employs a patented three-toothed or two-toothed base and a high-frequency breaker hammer for rapid rock fragmentation and powerful impact.

Remote Operation: Facilitates remote control of all machine movements, offering ease and convenience. Operators can adjust positions flexibly for optimal operation.

Dual Power System: Supports both diesel-powered emergency operations and electric-powered construction, reducing overall costs. This system prevents exhaust pollution and minimizes heat accumulation within the tunnel.

Efficient Slag Discharge: Certain models feature slag collecting and discharging devices with a capacity of 180m³/h, catering to small-section equipment needs for rapid slag removal without site disruption.
