Product Description

Rotary Drilling Rig Kelly Bar

Kelly bars are a key component on hydraulic rotary drilling rigs. They transfer the torque of the rotary drive and the crowd pressure of the crowd system concurrently to the drilling tool. Our kelly bars consist of 3-6 telescopic tubular sections with a system of drive keys and lock recesses that have been welded onto the outer surfaces. Standard kelly bars are produced with a total of 6 drive keys on each section. The tubular kelly sections are manufactured from high tensile steel to ensure the minimum weight has the right strength for different applications.
