The rugged and reliable universal boom features an optimal cross-section coverage shape. The 360° rotation and automatic leveling of the feed beam enable fast and convenient drill hole positioning. The boom can also be used for sidewall cross-cut opening and roof bolting operations. The drill rig layout ensures good visibility for the operator. The well-balanced, powerful four-wheel drive articulated chassis ensures flexible, fast, and safe travel in narrow tunnels. The high-frequency impact rock drill uses a stepped piston to optimize shock wave transmission efficiency, increasing drilling speed, reducing steel wear, and improving equipment availability. The spacious working environment and a range of automatic functions help the operator stay focused on drilling safely, quickly, and accurately. All maintenance points are well protected while remaining easy to service.
