What is a kelly bar?
The Kelly bar is a long, telescopic tubular structure that connects to the rotary drilling rig's turntable, crucial for transferring drilling torque from the rig's power source to the drilling tools. This connection is essential in maintaining consistent force and stability across drilling operations, ensuring smooth, reliable performance throughout the project.
As the backbone of drilling, Kelly bars come in various lengths, diameters, and configurations to accommodate different drilling depths, soil compositions, and rig capacities. Selecting the appropriate Kelly bar is critical for efficient and successful drilling, particularly in challenging soil and foundation conditions.
Our RCQ series rotary drilling rigs, with depths ranging from 15 to 50 meters, are suitable for diverse subsurface conditions. The kelly bar rotary drilling machine is widely used in sand, clay, and silt soils for projects involving bored piles, continuous walls, foundation reinforcement, and other foundational construction tasks.
