The Electro-hydraulic cutter EHC-03

A new product for cutting various rocks: granites, marbles, basalts etc. It can also be applied for the demolition of brick walls and cement panels (reinforced by metal grid of different diameter).

The cutting action of the EHC is enabled by an explosion, which is produced by applying an electric current from a high-voltage power source through an electrode that is lowered into holes filled with water.

No matter where the EHC-03 is used — in demolition (old houses, factories, brick walls, cement panels etc), or in construction (road construction in mountainous terrain, natural stone cutting for decorative purposes), it provides maximum capacity and low energy consumption that minimizes the user’s capital costs.
