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.

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.
