The HRD system consists of a rock drill, power pack and a selection of pusher legs.
The focus for our dvelopers was to provide hydraulic drilling that helps you exceed your production targets in a safe way. Thanks to the hydraulic system you don´t have to worry about loosing production time due to poor air pressure at large depths. We have also gone out of our way to design a system that helps you avaoid heavy lifting and wasting precious energy. We use best materials available and combine them with active security systems that protect both you and the equipment. After all, your business is our business.
The RD100 has a soft start function that is easy to reach with one hand. This means you can work with more precision, and collaring is made especially easy.
When it’s time to go faster, the RD100 is one of the most powerful drills on the market. The hydraulic system has an increased drill rate compared to electrical systems, and is considerably more energy efficient than pneumatic drills.
