Kelly Swivel is a critical component for rotary drilling rigs, designed to transmit high lifting force while allowing the Kelly bar to rotate freely during drilling operations. Manufactured from high-strength alloy steel with precision machining, it delivers excellent load capacity, wear resistance, and reliable performance in demanding foundation drilling applications.
Engineered for smooth operation and long service life, the Kelly swivel minimizes friction and ensures efficient power transmission between the rotary head and the Kelly bar. It is compatible with a wide range of rotary drilling rigs and is suitable for bored piling, bridge foundations, high-rise buildings, and other deep foundation projects. Rockway also offers customized Kelly swivels to meet different rig models and customer requirements.
