   Interlocking kelly bar

   Interlocking kelly bar systems are designed for drilling hard materials, as well as when a crowd force application is needed. Each section of kelly bars is made of seamless steel tube and the inner and outer key strips welded on it. 

   The distribution of outer key strips are divided into two types- one type with 3 key strips on kelly bar surface, the other type with 6 key strips, in the middle of outer key strips there are two or three pressuring

   plates. When the inner drive shell are rotated to the pressuring plates of outer driver keys, the pressure produced by the cylinders is directly transferred to the drilling tool.

   
   

   The purpose is to interlock each telescopic element to an inner following element in order to apply maximum torque and crowd 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 telescopic element to unlock.

   Friction Kelly bar

   The telescopic elements are advanced using a ‘friction contact ’ from each of the friction drive shell that run down the outside of each kelly bar.These drive shell are driven by rotary table and 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.

   Frictional kelly bars typically are available with 4, 5 or 6 telescopic elements. They are primarily used for deep piles in the medium hard soil conditions.
