Hunan Kellyway Machinery Co., Ltd

Interlocking Kelly Bar is a multi-section drilling bar used on rotary drilling rigs for foundation and piling projects. Torque is transmitted through mechanical interlocks between sections, providing higher torque capacity and more stable rotation than friction kelly bars. This design is ideal for large-diameter piles and hard or complex ground conditions. Interlocking kelly bars can be customized in length, diameter, and connection type to match different rigs and project requirements, ensuring reliable performance in deep foundation drilling.
