Yamamoto Hydraulic Rock Splitters excavate hard rock without the worry of vibrations, flyrock, or hazardous noise. Hydraulic rock splitters are a solid alternative to blasting methods. The rock splitter method is based on the traditional wedge and feather methodology but uses hydraulic power to split the rock instead of impact force.
The splitter is normally mounted on an excavator and uses the hydraulic power of the carrier. But it can easily be used on a crane or custom carrier, it all depends on the type of project. The simple installation method allows it to be moved from carrier to carrier without any major modifications, so the same splitter can be used in many different types of applications.
For large-volume rock excavation in hard rock, there is simply no mechanical method more efficient, safe, and quiet than Yamamoto Hydraulic Rock Splitter. This is the reason it has been used worldwide in some of the most challenging construction projects.

- Simple, reliable, and durable with minimal moving parts.
- Zero noise! No impact or vibration
- 2 models to fit carriers 12+ tons
How does Yamamoto Rock Splitter work?
The working principle of the Yamamoto Rock Splitter is based on two counter wedges inserted in a pre-drilled hole. A hydraulic cylinder pushes out a center wedge between the counter wedges to spread them apart and the rock is forced to crack.
Insert half of the total length of wedge and operate the Yamamoto splitter to split.
Then insert about ¾ of the total length of the wedge to split again.
Finally, insert the total length of the wedge and split to complete.
The larger wedge increases the spacing between holes and allows for deeper cracking with each split.
Robust and Durable
Designed with minimal moving parts, utilizes the pressure of the carrier.
Constant hydraulic force is much quieter than impact tools.
