Hydraulic splitter

The hydraulic splitter, also known as rock splitter and darda splitter, is a type of portable hydraulic tool that is used in demolition jobs which involve breaking large blocks of concrete and rocks.

There is also a larger excavator mounted rock splitter from Yamamoto Rock Machine, which is suitable for excavation of large volumes of hard rock where blasting is not practical or allowed.

Hydraulic rock splitters consist of two wedges which are inserted in a pre-drilled hole and a hydraulic cylinder is pushing out a center wedge between the two side wedges forcing them to separate. Hydraulic splitters are now available at hire shops or another alternative could be Expando non explosive demolition agent.
