An Xcentric revolution in excavation

Xcentric ripper
Using impact vibration accumulation technology, the hydraulic ripper works with the natural rigidity of the rock.

After more than a decade of development in the design and manufacturing of hydraulic rippers, Xcentric Ripper has taken its range to a new level with the release of the all new XR Mining Series.

According to the company, the Xcentric Ripper outperforms traditional hydraulic hammers and static rippers, particularly in medium hardness rock with natural fracturing and layers.

Using patented impact vibration accumulation technology, the hydraulic ripper attachment works with the natural rigidity of the rock. The vibrations that are produced shake the material to deepen cracks for easier breakup.

While the working technology is based on the standard series, the new Mining Series is reinforced with a remodelled working platform, which delivers a higher energy impact force to the work tool with a lower frequency. Larger and heavier eccentric gears are now machined from a single billet of steel and designed to allow for equal weight distribution side-to-side and direct impact energy vertically. The lower pivot arm and housing is reinforced to limit wear where the ripper typically encounters material. As well, the ripper arm or beak has been remodelled and reinforced with Hardox steel.

The XR Mining Series also has a narrower body profile, making it ideal for tunnelling or operating in confined areas.

Like the regular series that came before it, the Mining Series is capable of for frozen ground excavation, rock excavation, quarrying, surface and underground mining, oil sands excavation, utility project installations, pipeline trenching, demolition, slag recycling, dredging, and even underwater applications.

One of Xcentric Ripper’s customers in the pile and dredging industry was searching for an excavation tool that could be deployed for a three-month project, which included the removal of more than 36,500 metres of basalt from a shoreline to make way for a new harbour and breakwater for incoming marine traffic. The superintendent saw video of the new XR Mining Series working online and decided to give the new version of the hydraulic ripper a chance.

“We have the XR82 model working on one machine and a clam shell bucket for dredging on the other,” he said. “We needed a tool that would work well under water and the XR82 has performed to our expectations so far. I see it proving valuable as an asset in our equipment fleet and working really well on some of our more specialty projects.”
