for melioration, mining, civil engineering.

The machine is used for preliminary no-splinter crushing of bulky rocks.

 The crushing is caused by an electric-hydraulic shock inside the hole drilled in the rock. The high-voltage discharge is initiated in the liquid poured into the hole.

 Possible applications:

  • Crushing of concrete and brick basements and constructions, especially in complicated geometry and operation conditions.

  • Excavation of stone and rocks.

  • Passivation of granite monoliths.

  • Production of drilled piles with the effectiveness doubled in comparison with conventional process.

  • Building basement reconstruction
