About as long as man has known rock, people have been designing and perfecting tools to demolish it. In recent years, hydraulic breaker technologies have evolved rapidly to include advancements that not only optimize breaking efficiency and reduce operating costs in a variety of rental applications, but they help minimize downtime on the job.
Rock can be successfully drilled with a tubular rock-breaking tool in a high-energy percussive rig, fitted over the outer surface of the striker mass, surrounding it, and pushed ahead of the striker mass by an amount of the order of the wall thickness of the tool. A tool and striker mass assembled in this way can also be used, without any modification, to break rock.
