Accessories Kelly Bar Swivel Head Spring drive key Spare Parts Of Kelly Bar
Kelly bar is made up of many parts,it has many accessories:Lift Joint Swivel Head,Shock Absorbing Spring,kelly drive key,Kelly Drive Adapter and so on,
The key parts of kelly bar such as drive key is widely used heat treatment to improve wear resistance.
With High torsional coefficient,the compression and vibration resistance of kelly bar is higher than average level,high efficient in rock drilling construction.
Frictional kelly bar
This type of the kelly bar is suitable for soft ground and mud, mud, (mud) sand, gravel layers.
It is convenient and fast to lift the bar because it does need to lock the joint of its inner and outer lining .
Non-stair key, friction transmission the outside key is made by highly wear-resisting tempering steel.
Interlocking kelly bar
Another type is fit for soft fromations, (weak) weathered rock, hard strata construction layers.
It is of great pressure transmission and good anti-contortion perfomance,even at the hard geologic condition it can transfer greater pressure and drill in.
This one has 3 rigid parts between drilling pipes to transfer greater pressure from embedding cylinder.
Stair key, organization transmission, the outside key is made by highly wear-resisting tempering steel.

1. Small clearance and high-precision mating of the drill pipe ensure its good working order and service performance.
2. Steel pipes through shot blasting have high surface quality and fatigue strength.
3.: Automatic welding equipment can reduce welding defects and promote the reliability of weld seam.
Kelly bars is to transfer to the drilling tools both the torque and the pressure produced by the drilling machine,it candrill in dense sand and gravel and weak to strong rock.
