Products Cylinder Overview Cylinder Overview DARDA Hydraulic Rock and Concrete Splitters offer a unique solution to conventional demolition and excavation work. DARDA Hydraulic Splitters and ELCO Hydraulic Power Units are extremely robust and effective demolition tools that will save time and money on projects. From solid bedrock to reinforced concrete, DARDA is the answer. Click on a tab below for more details on the product. C2 C2 Handheld Splitter The Darda C2 is the smallest splitting cylinder. The C2 is suited for light projects such as sidewalk and step removal, pipe-jacking, and landscape work. The small size of the splitter makes it ideal for close-quarters applications where small amounts of rock need to be removed. The cylinder can also be used for secondary splitting of boulders or ledge rock.Order Elco Part No: -2IMPORTANT: Splitters must be lubricated with ELCO LUBE-PASTE. Failure to do so will result in premature wear and tool failure.Technical DataHole DiameterHole DepthEffective ForceWeight1-3/16 Inches12 Inches220 Tons45 Pounds C9 C9 Handheld Splitter The Darda C9 is a medium sized splitting cylinder. The C9 splitter is well suited for demolition of concrete, rock, and production work in sandstone formations. The cylinder is exceptionally good at the demolition of non-reinforced concrete, applications in confined spaces, demolition of slabs, and secondary splitting of rock. The cylinder is also best suited for underwater demolition due to its light weight and high power.Order Elco Part No: -9IMPORTANT: Splitters must be lubricated with ELCO LUBE-PASTE.

The C12 is extremely well suited for the demolition of harder materials where high production rates are essential. This splitter is excellent at breaking reinforced concrete, hard bedrock and boulders, and for the production of granite blocks in the natural stone industry. These units can effectively remove blocks of rock that weigh in excess of 50 tons.Order Part No: -12IMPORTANT: Splitters must be lubricated with ELCO LUBE-PASTE.

The air motor requires 50 to 80 CFM at 100 PSI. The air must be clean, dry, and lubricated. The Elco air powered hydraulic power unit is well suited for remote sites where large air compressors are readily available.Order Elco Part No: 02Conversion kits are offered for quickly changing between air, gas, and electric power sources. Units are shipped dry. Oil capacity is 5 gallons. IMPORTANT: Splitters and hydraulic power units MUST use Shell Aero Fluid #4 or ExxonMobil Univis HVI 13. Electric Hydraulic Power Unit Elco Accessories Elco Accessories Flowbar Manifold: Run up to five C-12, C-9, or C-2 splitters from one Elco Hydraulic Power Unit. A Flowbar Manifold is outfitted with quick disconnects that are mounted to an aluminum distribution block with up to five sets of 10-foot hoses. Flowbars can be ordered with 2, 3, 4, or 5 sets of lines. Each set of lines ordered will come with quick disconnects on one end so that the manifold can quickly be plumbed in-line with the hydraulic power unit. Use of a Flowbar Manifold will not reduce output pressures or effective force delivered by the splitter units. Flowbar manifolds are used for high-production and high-precision work where all tools are installed along a line and used to create connecting breaks or break loose extremely large blocks of rock. The use of a Flowbar Manifold is recommended over multiple individual power units and splitters. Elco Lubricant: Elco Lubricant is required for use of the splitters. Lubricant is packed in ½ and 1-pint cans and shipped in cases of 12.
