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.

Drilling angles are fully adjustable. Whether you need to drill horizontally, vertically, or at an incline-it handles it all with ease. It's not one of those rigid, inflexible machines limited to drilling in a single fixed direction. Furthermore, its articulation system is quite clever: the upper rotary head delivers powerful torque for smooth, precise angle adjustments, while the lower section offers significant lateral swing to both the left and right. What does this mean in practice? It means you don't have to constantly reposition the entire vehicle; you can drill multiple adjacent holes from a single stationary spot. Given the cramped confines of a tunnel, saving even a single vehicle maneuver translates into saving several valuable minutes.

In terms of power, the machine features a dual-system setup comprising both a diesel engine and an electric motor. Simply put: if electricity is available, you can plug it in to operate-saving on fuel costs; if you're working in an area without power access, you can switch to diesel to get the job done. It's adaptable to any job site and won't cause you any headaches.

As for drilling depth, the machine can drive a substantial distance into the rock in a single pass. Unlike standard anchor bolt holes, anchor cable holes demand greater precision; this machine makes controlling that depth remarkably easy. The drill assembly features a built-in extension reserve; if you're just shy of reaching the required depth, you can extend the drill head forward an extra section without having to drive the entire vehicle closer.

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.
