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: -2

IMPORTANT: Splitters must be lubricated with ELCO LUBE-PASTE. Failure to do so will result in premature wear and tool failure.

C20 Carrier Mounted Splitter

The C20 is the largest Darda splitting cylinder and is designed to be used in conjunction with a 5-7 ton excavator. The cylinder is mounted to the carrier using one of four different methods: chain, carriage, and two different types of rigid mounting configurations. The C-20 is extremely well suited for ledge work and larger trenches, and is effective at removing large blocks of rock.

Air Powered Hydraulic Power Unit

The Elco air powered hydraulic power unit consists of an air motor, hydraulic pump, hydraulic reservoir, and pressurematic valve, all contained within a compact package. 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.

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.
