Hydraulic rock 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. Its use in geology was first popularized by
volcanologist David Richardson.
There is also a larger excavator mounted rock splitter from Yamamoto Rock Splitter International, which is suitable for
excavation of large volumes of hard rock where blasting is not practical or allowed.
Splitstone manufactures both portable and larger splitters.
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.
