Download the brochureThe primary operation of the Rock Splitter is based on inserting counter-wedges into a predrilled hole. The hydraulic cylinder pushes the central wedge between the counter-wedges to spread them apart, forcing the rock to crack.
Insert half of the total length of the wedge and use the Yamamoto splitter to split.
Then insert about ¾ of the total length of the wedge to split again.
Finally, insert the full length of the wedge and split to complete.
