Product Description:

A Kelly bar is an essential element in hydraulic rotary drilling rigs, acting as a telescopic shaft that conveys both torque and crowd force from the rig to the drilling tool. This component is vital for achieving deep drilling, enabling the rig to penetrate greater depths. It plays a key role in numerous applications, such as foundation drilling, construction projects, and mining operations.

Kelly bars can be categorized into two primary types: friction kelly bars and interlocking kelly bars. Friction kelly bars derive their name from the frictional interaction between the rails of each segment. In contrast, interlocking kelly bars lack this frictional contact; instead, they feature drive ribs equipped with locking devices that enhance torque transfer to each section. Standard kelly bars are designed as fully lockable systems, incorporating a mechanical locking mechanism that connects each element to both the outer bar and the rotary drive.

Features:


Kelly bars can be equipped with various standard features, such as:

  • Telescopic designs ranging from 2 to 6 elements for piling applications
  • Depth capabilities spanning from 10m to 110m
  • Torque transfer capacities varying between 80kNm and 500kNm
  • Options for both interlocking and friction kelly bars
  • High-quality seamless steel tubing
  • Six cams and drive ribs for enhanced functionality
  • A top flange for connecting the kelly bar to a kelly swivel
  • Upper and/or lower spring shock absorbers for added stability
  • A square kelly box for attaching drilling tools
  • A drive pipe that facilitates the transfer of torque and crowd force to the kelly bar

When selecting a kelly bar for a drill rig, it's crucial to prioritize bars constructed from high-quality steel with robust mechanical properties. Whether opting for new or used kelly bars, it's beneficial to seek those accompanied by origin and quality certifications to ensure their durability and reliability. Additionally, all kelly bars can be equipped with a noise-damping system designed to minimize disruptive, high-frequency sounds generated during operation. This system consists of a sound-absorbing material applied to the outer section of the kelly bar, which is safeguarded by steel plates.
