Xcentric Ripper is a revolutionary excavator attachment for excavation of rock and demolition of concrete structures. It is based on a patented impact vibration accumulation technology, which enables excavation and demolition in less time, for lower cost and with minimal noise. It was developed in Spain and has been used with great success in Europe since 2009. Now it is also available in Asia! The Xcentric Ripper combines the working principles of impact force of a hydraulic breaker with vibration and ripping power of a conventional ripper. Due to this combination of both breaking, vibration and ripping, it can yield up to five-times higher excavation rates compared to conventional hydraulic rock breakers. Xcentric Ripper is exceptionally suitable for soft to medium hard rock like limestone, sandstone and basalt, as well as reinforced concrete. Xcentric Ripper should not be confused with conventional vibro rippers as Xcentric Ripper has an accumulator which provides impact along with vibration. Key features of the Xcentric Ripper include: Up to 5X higher productivity Minimum maintenance Minimum noise Easy operation The Xcentric Ripper's closed energy chamber cannot be influenced or damaged from the outside by dust, water or dirt. Therefore it can work without any problem in the most severe conditions including tunnels, foundations, even under water. The Xcentric Ripper requires no greasing, no replacement of bushes, seals or any other parts.

Hycon offers a full range of powerful and reliable handheld hydraulic breakers with highly portable power packs. Compared to pneumatic breakers, hydraulics offers a higher performance but with lighter weight. For instance, a Hycon hydraulic breaker weighing 23kg driven by a 9hp power pack has the same breaking power as a 27kg pneumatic breaker with a large compressor. This allows the same job to be done faster but with lower fuel consumption, lower investment and easier transportation. You can also use the same power pack to operate pumps, cut-off saws, core drills, etc. Hycon's handheld cut-off saw is one of the most powerful handheld power saws on the market but is still light enough for easy use in all positions. The cut-off saw is available in 3 versions: HCS14, HCS16 and HCS18. All types can be used for to cut all types of concrete, steel, brick wall, asphalt etc., even under water. The tool automatically cuts off if the disc jams so there is risk of injury to the operator.

Explosives or large rock breakers are the normal methods for excavation of hard rock. But restrictions on blasting are getting stricter and the use of rock breakers is not always feasible due to vibrations, noise restrictions or simply to hard rock. Yamamoto ultra-large rock splitters offer an alternative method for efficient excavation of large volumes of hard rock without the need for explosives, vibrations or fly rock. The splitter can be mounted from a crane or a normal excavator for open pits or shafts, or mounted on a specialised carrier for horizontal tunnelling. For large volumes of rock, there is simply no mechanical method more efficient, safe and silent than the Yamamoto rock splitter. The working principle is based on a two counter wedges inserted in a pre-drilled hole. A hydraulic cylinder pushes out a centre wedge between the counter wedges to spread them apart and the rock is split.

Hydraulic rock and concrete splitters providea powerful and extremely cost-effective alternativeto other conventional demolition techniques.Hydraulic splitting means controlledsplitting, and this method eliminates shockwaves, vibrations, dust and noise that largeimpact tools usually produce. DARDA rockand concrete splitters have been used withgreat success in over 80 countries for thepast 30 years. The high quality, reliabilityand durability of the equipment is unsurpassed.
