Features

Automatic gearbox

Automatic gearbox

Four electronically adjustable speed ranges and automatic torque regulation allow for perfect adaption to the prevailing soil conditions. The drilling process is not interrupted through changing speed.

Rotary drive with selective Kelly shock absorber

Rotary drive with selective Kelly shock absorber

The latest version of the rotary drive has a newly developed Kelly shock absorber, which allows the damping strength to be adapted depending on the respective weight of the Kelly bar. more

Applications

Kelly drilling

Kelly drilling

Kelly drilling belongs to the most common dry rotary drilling methods. Soil and rock material is conveyed to the surface discontinuously with relatively short rotary drilling tools.

Continuous flight auger drilling

Continuous flight auger drilling

The loosened soil material is continuously conveyed to the surface using a continuous auger, the so-called continuous flight auger.

Full displacement drilling

Full displacement drilling

Full displacement drilling is a modification of continuous flight auger drilling. The drilling tool used is a smooth pipe with an auger-type starter piece.

Down-the-hole drilling

Down-the-hole drilling

For down-the-hole drilling a hammer is mounted on the lower end of a drill rod. The hammer is activated by adding compressed air.

Wet soil mixing

Wet soil mixing

For wet mixing a self-hardening suspension is introduced into the ground.
