HC 25 Hydraulic Rock Drill

Compared with the traditional pneumatic rock drill, hydraulic rock drill has the characteristics of less power consumption, high energy utilization rate, high drilling speed, easy operation and strong adaptability.
Drilling hole diameter :38-64mm
Rated power :8kw
Impact frequency :38-64Hz
Application conditions: mining, foundation engineering, water conservancy engineering.

Product Introduction

1. Energy Recovery Valve

This valve allows the piston rebound energy to be utilized for the next impact, providing the rock drill with a significant impact: the Safe Energy.

The unique design of the piston produces a perfect trapezoidal shape of the shock wave for better energy.

Minimized stress on the drill pipe, better penetration of the drill bit.

2. Hydraulic Damping System

The action of the damping piston not only absorbs the lost portion of the reflected energy, but also ensures a constant thrust on the rock drill.

Optimized shock wave transmission Protects drifter and tools by reducing vibrations.

3. Shock preparation

The optimal hydraulic reverse impact system ensures a true reverse hammering.
