Description
  • What is Big Hydraulic Rock Splitter for Excavator?

  • The use of explosives are the most common methods for excavation of hard rock. However, restrictions on blasting are increasingly strict and requires permits and inspections. In densely populated or otherwise sensitive areas, blasting may be completely banned due to concerns about vibrations, flyrock or other safety aspects.
  • Big Hydraulic Rock Splitter was designed as a mean to excavate hard rock without any concerns for vibrations, flyrock or noise. The method is based on the traditional wedge and feather method but is using hydraulic power to split the rock instead of impact force.
  • The splitter is normally mounted on a normal excavator and uses the hydraulic power of the carrier. But it can easily be used on a crane or tailor made carrier, 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 project.
  • For large volume rock excavation, in hard rock, there is simply no mechanical method more efficient, safe and quiet than Big Hydraulic Rock Splitter. This is the reason it has been used in worldwide in some of the most challenging and important construction projects.

How does Rock Splitter work?
The working principle of Big rock splitter is based on two counter wedges inserted in a pre-drilled hole. A hydraulic cylinder pushes out a centre wedge between the counter wedges to spread them apart and the rock is forced to crack.


1st Step:

Insert half of the total length of wedge and operate the Yamamoto splitter to split.

2nd Step:

Then insert about ¾ of the total length of the wedge to split again.

3rd Step:

Finally, insert the total length of the wedge and split to complete.
