Hydraulic Casing Rotator (RDM)

The hydraulic full 360 degree turning casing rotators are economically used to construct bored piles with the full casing method under hard soil conditions. The continuous cutting of the hard ground guarantees a boring speed satisfying to-day's requirements, even for compressive resistance of up to 2500 kg/cm2.

The full 360 degree continuous turning of the casing minimizes the friction compared to the oscillating method allowing the casing to drill down to 100 m depth with the casing rotator machines.

The first casing is fitted with carbide bits which can be adapted to the requirements of the soil conditions offering major advantages when coring through hard rock layers or when constructing secant pile walls.

The full 360 degree continuous turning of the casing by powerfuil hydraulic motors eliminates the possibility of pile misalignment.

Beyond that, the casing rotators are especially suitable for the construction of full casing displacement piles because of the ability to apply very high torque, push down and lifting forces on the casing which is not possible with the known drilling rigs.
