High carbon steel Kelly Bar Piling Tool Drilling Rig Parts Thick Inner Outer Key

Deep Drilling Kelly Pilling , Soilmec Kelly Bar Peripheral Force Produced

Kelly bar is the key part of a rotary rig, the aim is to transfer to the drilling tools both the torque and the pressure produced by the drilling machine..

The high quality of the components, all certified steels for the high mechanical features together with the strict procedures of the quality system ISO 9002, allows us to guarantee the highest reliability.

1) Interlocking kelly bar

Interlocking kelly bar is used for drilling in dense sand,gravel and weak to strong rock .Interlocking kelly bar can be fully locked by mechanical locking system on each section.Kelly bar can be equipped with specially designed springs or pressure plates for shock absorbing purpose.

2) Friction kelly bar

Friction kelly bar is another type which the external key is composed of 3 or 6 wear -resistant strip without pressunrizing point .This kelly bar can transform pressure when it is working.Also can produce peripheral force and pass down the pressure force,can produce the friction force.This kelly bar has the advantage of operating sample ,drilling deep ,but with less pressure transmission.So this one is suitable for the soft and silt layer.
