Casing machines KL type for combined use rotary drilling rigs
LEFFER offers short-design casing machines (type KL) to support the rotary drilling rig. In general, LEFFER casing machines have been designed based on specific experience.
The five-part clamping collar that surrounds the drill pipe prevents plastic damage to the pipe circumference and ensures efficient and force-fit transmission of torques and vertical forces.
- Thanks to our reduction inserts, our casing machines can be converted to small diameters in just a few minutes.
- The moment-resistant attachment to the excavator guarantees the transmission of the full oscillating movement: This enables the pipe string to rotate up to 25° per oscillating movement.
- The low height on the excavator side allows 360° movement of the excavator upper carriage even when coupled.
With LEFFER casing machines, casing and drilling can be carried out simultaneously. Control can be via the carrier’s on-board hydraulics or LEFFER’s own power unit.
