Vibration Heads

Eurodrill Vibration Heads provide an ultimate drilling capacity with comparatively low power consumption. The modular design allows both a compact as well as a weight saving solution. Besides, the modern design enables a high productivity for most different requirements and operation conditions.

Advantages

Drilling capacity

Drilling depth
  • 70 m in sand / clay
  • Overburden technique
Drilling diameter
  • 220 mm in slope rubble with bolders

Flushing

If it is not allowed to flush with air

  • In or close to power plants
  • In inner-city locations

Cost per meter

If drilling performance and profit optimization are a decisive factor

Extension of the drill string

Wear-free pulling of the drill string

Additional Equipment

Cost reduction by saving additional equipment

Noise Emission

If the construction project has to be carried out in a noise-sensitive area e.g. Anchorages in inner city locations

A Vibration Rotary Head basically consists of 2 main components:

Rotation

The rotary mechanism ensures the simultaneous or even independent rotational movement.

Vibrator

The percussion unit converts the power supplied by the carrier into kinetic energy.

Vibration Drilling in Loose soil

Axial movement in drilling and oposite direction

  • The vibrating drill string moves the surrounding ground into motion
  • The drill bit displaces the soil
  • Cuttings are discharged by suitable flushing

Vibration Drilling in hard formation

Axial movement in drilling and oposite direction

  • The drill bit is smashing the rock
  • The drill bit is actively lifted after every impact
  • Cuttings are discharged by suitable flushing

VMS System

With the VMS system patented by Eurodrill the inner rod of an overburden equipment can be separated in axial direction at the vibration - rotary heads. Consequently the full vibration energy will be transmitted to the casing only, so a down-the-hole-hammer can be operated simultaneously.

Advantages of the system

Extension of the application possibilities with larger drilling diameters, drilling depths and/or shortened processing time

Enormous saving potential on fuel by reduction of the processing time

Simplification of the drilling system by saving cost-intensive DTH bits to retract the casing

Facilitation when removing the casing by reduction of the friction with vibration when removing, as it is continuously approved
