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 thrusting. In long-distance thrusting, if it encounters interlayer ground, bits can be exchanged from inside the machine according to the geological layers. Additionally, efficient thrusting can be achieved through high-torque primary and secondary crushing mechanisms. 【Features】 ■ Bit exchange can be performed from inside the machine during thrusting operations ■ Capable of long-distance and curved thrusting ■ Smooth thrusting operations can be achieved through the crushing action of the blade crusher inside the chamber ■ Remote operation allows for an unmanned interior *For more details, please refer to the PDF document or feel free to contact us.
