Hydraulic Splitter: What is it?

A hydraulic splitter is used to split concrete, stone or granite. It consists of a piston which forces a wedge between two feathers, creating a crack. It is faster, quieter and cleaner than other methods.

A hydraulic splitter is a device used to split or break concrete, stone or granite. Unlike a hydraulic log splitter which forces a wedge into a log, the hydraulic log splitter consists of a hydraulic piston which forces a wedge between two external components known as feathers. When the wedge is driven through the tapered feathers, the feathers are driven outward, against the rock or stone, and a crack results. Unlike a jackhammer or blasting methods, the hydraulic log splitter allows for the rapid removal of a concrete or stone object without dust, noise or danger to surrounding structures.

The typical hydraulic splitter is a hand-held device that looks like a cross between a hydraulic cylinder and a jackhammer. The cylinder component of the splitter features handles, switches and hydraulic hoses. After a hole has been drilled in the rock or concrete that needs to be removed, the splitter operator pushes the splitter’s piston-type component into the hole until the cylinder component is flush with the outside surface of the obstacle. It is not uncommon to use two to four splitters on a single hydraulic pump to create the crack or split. Once all the splitters have been inserted into the pre-drilled holes, the operator operates a switch at the end of the cylinder which sends the wedge through the tapered passage into the feathers.

As the wedge is driven through the feathers of the hydraulic splitter, the feathers are driven outward against the hole. This causes a crack or fissure to form which effectively breaks down the concrete or stone. Unlike a jackhammer which attempts to break stone by forcing a chisel into the stone’s surface, the hydraulic wood splitter uses internal force to create a crack without excessive noise, dust or time. The typical split produced with a hydraulic log splitter is done within seconds of inserting the log splitter into the hole.

When splitting occurs, the operator flips the switch from high pressure to low pressure and the feathers retract as the wedge is pulled back into the splitter. The advantages offered by the hydraulic log splitter over other methods are the time savings, the absence of dust and debris to clean up after the stone has been broken, and the noise and destructive force of an explosive agent on the surrounding area. The loudest noise and most of the dust produced when using a splitter comes from drilling the access holes for the splitters.
