drive and crowd pressure to the drill tools . a kelly bar consist
of 2-5 telescopic sections with a system drive keys and lock
recesses, welded onto their outer surface. Standard kelly bars are
fabricated with a total of 6 drive key on each sections.
Based on the rich manufacturing
experience and by absorbing the advanced technology at home and
abroad , we can produce first-class kelly bars which can be matched

Mait etc.
interlock Kelly bar adopts the
international advanced six-ribs distribution technology. This type
Kelly bar consists of telescopic tubular sections with a system of
multy-step drive keys and lock recesses, welded onto their outer
surfaces. The inner keyboards are manufactured from high-tensile
steel . The special heat treatment which make this style Kelly bar
with high abrasion resistance, compression resistance and excellent
welding properity.
interlock Kelly bar is based on
domestic rig configuration and condition demand, combined with the
