Kelly Bar Classification and Structure

Locking kelly bar systems are designed for drilling hard materials, as well as when a crowd force application is needed. They come with drive rails designed with locking pockets on there length and the corresponding terminal joint locking guides.

The purpose is to interlock each telescopic element to an inner following element in order to apply maximum torque and crowd force developed by the base rig. Due to this, the rotary tables inner drive is equipped with locking pockets.

When extracting the locking bar from the hole, a combination of lifting and rotating counterclockwise allows the telescopic element to unlock.

Locking bars typically come with 3, 4 and 5 telescopic element to unlock.

Drive rail steel quality: German imported steel palate

Drive stub steel quality: Special forged steel

Drive stub dimensions: 200*200, 150*150 or customized.

Outer pipe available diameter: 254, 292, 298, 305, 343, 368, 378, 445.

Upper shock absorbed systemDamping rubber ring

Lower shock absorbed system: Damping rubber ring and damping spring.

Number of telescopic elements: 3, 4, 5, 6, other on request.
