Spot Supply Hydraulic MONTABERT Rock Drills HC50

1

Energy recovery valve

This valve allows the rebound energy of the piston to be used for the next blow,

HC series drift machine has obvious advantages:

• Greater efficiency

• No peak within cavitation pressure source

• Optimal drift protection

2

Progressive blowing energy

Unique piston design produces perfect, long

Trapezoidal shock wave:

• Better energy transfer to bits

The drill string is subjected to minimal stress

• Better bit penetration

3.

Hydraulic damping system

The action of the damping piston is not only to absorb the loss

Reflecting part of the energy, but also ensuring sustained thrust against the tool:

• Optimal shock wave propagation

Protect the forklift and tools

• Reduce vibration

4

Hydraulic reserve shock

Optimal hydraulic counter-impact system ensures true counter-hammer:

• Tool extraction of fractured ground

• No rods in the hole

Straight hole drilling

• When used in conjunction with Montabert drilling controls
