To support the rotary drilling rig, LEFFER offers casing oscillators in short design (KL type) which features: 

• The five-link clamp, which encloses the casing, prevents plastic damage to the pipe circumference and ensures efficient and force-locked transmission of torques and vertical forces.
• Our casing machines can be converted to smaller diameters in a matter of minutes thanks to our reduction inserts.
• The torque-resistant attachment to the excavator guarantees the transmission of the full oscillating movement. This allows rotation of the pipe string up to 25° per oscillating movement.
• The low headroom on the excavator side allows a 360° movement of the excavator upper carriage even when coupled.
• LEFFER casing machines can be used to case and drill at the same time. It is controlled either via the on-board hydraulics of the carrier device or via a LEFFER-own unit.
