Top 10 kelly bar Manufacturers in China

Introduction to Kelly Bar

A kelly bar is a crucial component in foundation construction equipment, especially in rotary drilling rigs. It is a long, tubular structure with square or hexagonal cross - sections that transfers torque and axial force from the drilling rig to the drill bit. The kelly bar enables the drill bit to penetrate the ground, whether it's soft soil, hard rock, or other geological formations. It plays a vital role in various construction projects such as building foundations, bridge piers, and high - rise building construction. The quality and performance of the kelly bar directly affect the efficiency and success of the drilling operations.
