How the Hydraulic Splitter Works

    Forced expansion inside the material to be broken causes tensions in rock or concrete.  Once tension increases beyond the tensile strength of the material, a split will form.

    The hydraulic cylinder contains one sliding plug and two feathers.  The unit is inserted into a predrilled hole with the plug in a retracted position.  As the plug advances, the two feathers are pushed aside until the material is broken apart.

    The entire action of the cylinder is controlled by a single lever on the top of the cylinder.  The plug can be advanced, retracted, or maintained in any position.

Controlled Demolition Splitting

    Hundreds of contractors now use the hydraulic splitting method for demolition of both concrete and rock.  Many contractors have reported great savings in time and money using this new method.

    The hydraulic method has many advantages including less noise, no shocks or vibrations.  It eliminates blasting hazards, yet has over 700,000 lbs. of splitting force.  Engineered for heavy duty work, the tools are very efficient and require little maintenance.  Some units are still in operation after ten years of use.

    The cylinder together with the power unit is easily portable and can be transported from job to job in the trunk of a car.

Recommended Applications

    The hydraulic splitter has been designed to break large pieces many times faster than a paving breaker.  Removing large chunks increases your production, saves time, reduces costs.  Contractors use this hydraulic unit to break concrete walls, slabs, floors, foundations, bridges, dams, and all types or rock.. Excellent in reinforced concrete.

• Trench rock and boulders below grade can be broken with one or more hydraulic splitters.  Hydraulic splitting eliminates dangers associated with blasting.  These hydraulic splitters will also operate underwater without any modifications.
• The splitter was used to remove the ends from these overpass supports and form a keyway.  The hydraulic splitter broke the reinforced concrete wide enough to permit the cutting of the rods.  Note the large chunks removed with several breaks.  This method was less expensive than sawing or chipping the supports.
• Boulders of any size and shape are easily split into small pieces with a hydraulic splitter.  Rock near structures or roads can be quickly and safely broken and removed without shocks and vibrations.
• The hydraulic splitter can increase demolition production because the breaks can be sized to meet your removal equipment.  Many times more production than jackhammers.  The compact, portable power unit is easily moved to any job site.
• Hydraulic splitters are excellent for breaking the bond between rebar in both light and heavy reinforced concrete.  Cracks can be enlarged to cut the rods.  Presplitting reduces many hours of chipping work.  A published booklet describes the details of this operation.

Controlled Breaking Increases Production

Controlled Breaking Pieces as large as your equipment can handle (see photo) are quickly broken for removal.  Contractors using the splitting method can increase production and reduce the cost of demolition work.  Years of research and use on hundreds of job sites throughout the world has proved the splitter to be one of the most practical pieces of equipment for the demolition of concrete and rock.

Impact Breaking Paving breakers and large tracter mounted impact rams are limited to breaking rock and concrete into small pieces.  Demolition by noisy impact methods requires more energy, more time and is usually more expensive.  In comparison, the smooth operation of a hydraulic splitter quickly and almost silently breaks large chunks without shocks or vibrations.  Direction of breaks is easily controlled so pieces can be cut to desired size.

The No. 5 Cylinder is recommended for most demolition work (rock and concrete) and operates at 7100 P.S.I.  A complete operating unit consists of a cylinder, 30 Ft. high and low pressure hydraulic hoses, quick connect couplings, hydraulic pump and lubricant.
