When soil condition is unstable and easily collapsible, casing is required to make concrete pile for deep foundation.
Casing rotator is the best solution to drive and extract casing with good verticality.
This method is also vibration-free, even with the largest shaft diameter

With 360 degrees drilling, working a rotator with grab, drilling rigs and augers is
the efficient method of installing casing in hard & soft soil and rock layer.

Thanks to the rotating and oscillating mode, it has benefits for removing
existing concrete piles, cutting through concrete in secant piling
and penetrating inclined rock layers or large boulders.

casing rotator can be equipped with an optional crawler track and
power pack deck so it can have its own self-traveling capability.
