Drilling Rig use Interlocking Kelly bar / Friction Kelly bar
Kelly bar is a very important part for rotary drilling rig, because its quality directly affects the work efficiency by transferring up pressure to the down drilling tool. Our patent product(No.ZL2012 2 0161611L0) is a mix type of interlocking Kelly bar and full interlocking Kelly bar and can be variety kinds of match style, Which can be perfectly adapted to complicated geological conditions.
a) Interlocking kelly bar
Interlocking Kelly bar contains two type pressure modes: one type is 3 or 6 external keys with 3 or more concave pressure parts, the other is 3 external pressure strips with full pressure parts on it, which mostly matched IMT drilling rig.

b) Friction kelly bar
Friction Kelly bar is composed 3 or 6 wear-resistant seamless alloy strips by working through friction produced by rotary passing down the pressure force without concave pressure point. This type is suitable for both soft layer and silt layer.
