Komatsu Develops Articulating Boom Track Drills

Komatsu is expanding its P&H product line to include articulating boom track drills. The first machine in the series, the 44XT, is in testing at the company’s Arizona Proving Grounds and will be released later this year, the company reported.

The 44XT is capable of drilling 4-in.- to 8-in.-diameter holes using down-the-hole (DTH) percussive hammers. It is for surface mines and quarries, and is de-signed for pre-split drilling applications. “It starts with a safety-focused ergonomic machine layout that sits on a robust core design,” said Matt Collins, product director, drills, Komatsu Mining Corp. “We matched structural integrity with in-creased horsepower and compressor capacity, translating into higher torque and speeds for optimal drilling performance.”
