Heavy Duty Kelly Drilling System Long Service Life Yellow Color Hard Rock Drilling 0

Kelly bar is the key part of a rotary rig, transfer the torque of the rotary power head and the pressure of the rotary rig system to the drilling tools and its quality affects the performance of the whole machine directly.

A kelly bar consists of 2-5 telescopic tubular section with a system of drive keys and lock recesses weld onto their outer surface.

Based on the rich manufacturing experience and by absorbing the advanced technology we have two kinds of kelly bar, interlocking and friction.

Frictional kelly bar needn't unlock the joint of its inner and outer lining so that it is convenient and fast to lift the bar. Non-stair key, friction transmission the outside key is made by highly wear-resisting tempering steel. For layer of soft ground and mud, mud, (mud) sand, gravel

Interlocking kelly bar is of great pressure transmission and good anti-contortion perfomance. There are 3 rigid parts between drilling pipes to transfer greater pressure from embedding cylinder. And even at the hard geologic condition it can transfer greater pressure and drill in. Stair key, organization transmission, the outside key is made by highly wear-resisting tempering steel. For soft fromations, (weak) weathered rock, hard strata construction.
