ROCK EXCAVATION BY HYDRAULIC ROCK SPLITTER
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. It’s the perfect alternative to blasting in densely populated and sensitive areas.
- Vibration-free
- Projection-free
- Environnemently friendly (zero emission)
- Predictable
- Constancy
- Silent operation
HOW IT WORKS
The working principle of the 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.
-
1st Step :
Insert half of the total length of the 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.
