Atlas Copco launches hydraulic underground handheld rock drill aimed at large depths
The new hydraulic underground handheld rock drill-system (HRD100) 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 crucial benefit of the HRD100 has an outstanding drill rate and considerable energy efficiency compared to conventional pneumatic or electrical rock drills. Measured noise is approximately 50 percent lower than that of a pneumatic drill. The polyurethane cover shields noise and makes the unit shockproof. The unit can handle a drop from two metres.
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 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. “We really made an effort to provide high drill rates at low operational cost. But it is equally important to create a system that save the operators energy by being light and reliable”, says Oleg Korobotchkine the product line manager. 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 you to work with the PP100 at a 45° angle, without power loss. Simple tools make it easy to top-up hydraulic oil in the mine.
