Kelly Bar Classification and Structure
Locking kelly bar systems are designed for drilling hard materials, as well as when a crowd force application is needed. They come with drive rails designed with locking pockets on their length and the corresponding terminal joint locking guides.
2.Main features for Our Friction Kelly Bar
(1) We supply kelly bars for a torque range of 100-400 kNm and in lengths up to 70 m.
(2) High-grade materials and special welding guarantee a high durability and wear resistance of our kelly bars.
(3) We individually adapt our kelly bars to your drilling and rotary power head.
(4) All kelly bars are available as friction and interlocking version.
(5) Our kelly bars transfer the maximum torque over the full extended length.
(6)High strength steel tube material is picked and heat-treated to arrange production, which enables the Kelly bars to work well under maximum torque of the torque output.
(7)Kelly keys and guides inside Kelly joints are made in highly wear-resistant material for
The purpose is to interlock each telescopic element to an inner following element in order to apply maximum torque and crow force developed by the base rig. Due to this, the rotary table's inner drive is equipped with locking pockets.
When extracting the locking bar from the hole, a combination of lifting and rotating counterclockwise allows the telescopic element to unlock.
Locking bars typically come with 3, 4 and 5 telescopic elements.

Friction kelly bars transfer the torque to the drilling tool. The telescopic elements are advanced using a "frictional contact" from each of the friction drive rails that run down the outside of each kelly bar. These drive rails are driven by the rotary table and the terminal joints of each successively larger diameter kelly bar. The terminal joint is a long piece on the inside and bottom of each kelly bars.
Friction kelly bars typically are available with 3, 4, 5, or 6 telescopic elements. They are primarily used for deep piles in medium hard soil conditions.
