Hydraulic rock drill

Fourth Quarter 2022 Hydraulic systems & components

Epiroc continues its proud reputation for setting the global industry benchmark in the design, manufacture and supply of high-quality machines and equipment for mining, infrastructure and natural resources sectors, with the smart HRD100 Hydraulic Rock Drill.

This complete handheld drilling system, consisting of the rock drill, power pack and a selection of pusher legs, is specially designed to provide efficient, accurate and safe hydraulic drilling of blow and support holes. The innovative HRD package offers a convenient and cost-effective plug-and-play solution, requiring only electricity and water to operate, thus eliminating the need for compressed air infrastructure installation and reducing maintenance.

Incorporating advanced technologies and cutting-edge design features, this remarkable tool enables end users to reach and even exceed production targets while keeping operators safe. Reliable operation, long service life, minimum maintenance and reduced operating expenses deliver lowest possible total cost of ownership for end users. “The HRD offers everything that endusers demand from their hydraulic drill, namely best-in-class energy efficiency, accuracy, reliability, performance, safety and serviceability,” says global product manager, David Baird.

High operational performance means that more holes can be drilled per day per operator, enabling the complete drilling cycle to be achieved within the required cycle time. Also adding to uptime and productivity is the fact that the hydraulic system delivers optimal drilling at large depths. Furthermore, the energy-efficient HRD100 uses only 10 kW regardless of depth, compared to a pneumatic drill that requires 34 kW to run at levels close to the surface, while at depths of 1 km below surface this can increase significantly.

Baird points out that HRD100 achieves faster drill times and ultimately increased production but never at the expense of the operators. Faster penetration rates and drill times reduce operator exposure in dangerous areas. “Our mandate is to ensure that our customers benefit from high productivity combined with high safety. Designed with operator comfort, health and safety top of mind, the HRD100 incorporates safety features that are amongst the best in the world,” he says. Weighing only 33,8 kg, the lightweight HRD100 is easy to manoeuvre, reducing operator fatigue. The tool’s low noise levels (105 dBA) reduce the risk of hearing loss, while lower vibrations help to avoid white knuckle-disease.

The PP100 power pack has been designed to keep weight to a minimum to facilitate lifting and moving. It features a robust frame and stainless steel cover. Data such as drill time can be downloaded directly from the USB port during run time and a full service schedule indicates service intervals and maintenance.

The HRD is also kind to the environment; drill grease is not blown into the air as with pneumatic drills, nor is there a risk of pneumatic grease contamination. The Hydraulic Rock Drill also uses less water while drilling (12 l/min), and the automatic water function stops flushing when drilling ceases. All four pusher legs, connected to the rock drill via a single port connection, are smartly powered by the same water that is used for cooling the power pack and for flushing.

The HRD100 is built to last. The robust components are manufactured to deliver long service life. The recyclable Rock Drill covers protect the equipment and help to further reduce noise and enhance vibration damping. Skilled Epiroc technicians offer operator training to ensure the optimal functioning of the Hydraulic Rock Drill so that customers can reap the full benefits.

According to Baird, southern Africa, South America, Canada, and Russia show tremendous potential for the Hydraulic Rock Drill due to the size of the underground mining industries in these regions, while smaller regions are showing increased interest due to the safety and efficiency of the HRD system. “Increasing restraints on electrical supply and ever stricter personnel safety and environment legislation are global dynamics. Designed to meet these requirements, the HRD100 is exactly what the market needs now. So, over the next three years, we expect to see a significant increase in the demand for the hydraulic tool from sectors around the world. Combining smart technology with exceptional design features, Epiroc is poised to change the scope of hydraulic rock drilling in conventional and underground mines and on construction sites in years to come.

SA Gauge Editor's Choice Hydraulic systems & components
Water hammer is a high-pressure surge or wave created by the kinetic energy of moving fluid when it is rapidly forced to stop or change direction, altering the liquid’s velocity. The progression of the water hammer shockwave needs to be detained and slowed before reaching the instrument sensor. SA Gauge manufactures several such devices in order to achieve this.
