Atlas Copco launches hydraulic handheld rock drill aimed at great depths

first_imgThe new hydraulic underground handheld rock drill-system (HRD100) from Atlas Copco is one of the most powerful underground handheld rock drills on the market. The smart power pack monitors all vital functions and can compensate for pressure changes automatically. The HRD system consists of the rock drill (RD100), the power pack (PP100) and a selection of water pusher legs. All hoses and cables are included.The crucial benefit of the HRD100 has an outstanding drill rate and considerable energy efficiency compared to conventional pneumatic or electric rock drills. Besides being one of the most powerful tools on the market, the HRD100 rock drill is silenced. Measured noise is some 50% lower than that of a pneumatic drill. The polyurethane cover shields noise and makes the unit shockproof. The unit can handle a drop from 2 m.Quality rock drilling means using just enough water for flushing. The HRD100 features a five-step water adjustment to help the operator use the right amount of water for each step. And when the drilling stops, the flow stops automatically. There is still the ability to force in water to flush out the drill if jammed.“We really made an effort to provide high drill rates at low operational cost. But it is equally important to create a system that saves energy by being light and reliable”, says Oleg Korobotchkine the Product Line Manager.User-centric design is at the core of the HRD-system. One example is the soft start function that makes collaring especially easy. Another is the replaceable rotation chuck, which saves service time. Working underground is hard work, but thanks to one-handed operation and carrying handles, the HRD-system makes it easier.The stackable PP100 power pack basically manages itself. Smart functions monitor oil flow and oil temperature. Water-cooling and automatic overheat protection means safety and reliability are at its core.The system also monitors oil volume and compensates for pressure differences. That allows working with the PP100 at a 45° angle, without power loss. Simple tools make it easy to top-up hydraulic oil in the mine.To minimise waste, the water used for cooling and flushing also powers the pusher legs. The legs are suited for narrow-vein mining. The drill steels are made from tungsten carbide steel.last_img
