Products Description
The moment you drive this machine into a tunnel, your immediate impression is this: it's incredibly stable.
With its wide chassis and sufficiently broad tracks, it traverses rough terrain-strewn with loose rock or thick mud-with absolute steadiness. Unlike some vehicles that wobble and sway after moving just a few feet, this machine feels solid and grounded.
Once you reach the work site, simply extend the two hydraulic stabilizers on either side; the entire vehicle then feels as if it's been bolted firmly to the ground. When drilling angled holes, the chassis remains completely motionless-no twisting or shifting whatsoever.




Thermal management is also a non-issue; even after a full half-day of continuous operation, the hydraulic lines remain cool to the touch-never too hot to handle.
The overall dimensions of the vehicle are just right, allowing it to pass through tunnel portals and entryways without any difficulty. When operating from the ground, the controls are positioned at a comfortable, ergonomic height-meaning you won't have to constantly crane your neck upward to monitor the work.
After using it for a while, you're left with just one overriding impression: this machine never fights you-it simply gets the job done.
