Internal diameter of 1000 to 3000 mm! Thanks to the crushing action of the blade crusher, smooth propulsion construction is possible!
The "DH-L" is a tunneling machine that enables long-distance propulsion. In long-distance propulsion, if it encounters interlayer ground, bits can be exchanged from inside the machine according to the strata. Additionally, efficient propulsion can be achieved through high-torque primary and secondary crushing mechanisms. 【Features】 ■ Bit exchange can be performed from inside the machine during propulsion construction ■ Capable of long-distance and curved propulsion ■ Smooth propulsion construction is possible due to the crushing action of the blade crusher within the chamber ■ Remote operation allows for an unmanned interior *For more details, please refer to the PDF materials or feel free to contact us.
