XDN-R Series Pipe Jacking Machine

1. Electric-driven rock pipe jacking machine, mainly suitable for gravel, cobble, a small amount of boulder, and rock strata.

2. High cutterhead power, equipped with a high-torque reduction gearbox, strong rock-breaking capability.

3. The main jacking system features a fine adjustment mode, enabling millimeter-level precision adjustment per minute to meet the construction requirements of extremely hard rock strata.

4. The slurry supply and discharge system supports five slurry circulation modes: internal circulation, external circulation, bypass, external water supply, and direct discharge, effectively solving problems such as debris accumulation and high pipeline friction resistance.

5. Equipped with a retractable anti-rotation device, effectively solving the problem of the machine head being prone to rotation during construction in rock strata.
