FAE all types of rotary drilling interlocking and friction kelly bar Specifications Interlocking and Friction kelly bar:
1.Light weight
2.High strength
3.Good abrasion resistance
4.Cost-effective
Product Description What could FAE kelly bar offer? Kelly bar is the key part of a drilling machine, and its quality directly affects the whole machine based on the rich maunfacturing experience and by absorbing the advanced technology both at home and abroad, we can produce first-class kelly bars which can be matched with drilling rigs of Bouer, Sany, Soilmec,MAT,IMT,Casagrande,etc Advantages The features of FAE kelly bar are as follows: 1.Adopt the advanced technology of 6-key design in the world and standard modulor design 2.Equipped with advanced processing facilities . processing technic and manufacturing equipments,DZ kelly bar enjoys a low weight,high strength,high straightness of single bar,thinner tube,smaller inter-tube distance and good resistance. 3.The raw materials are either imported from Germany like the high abrasion resistance materials ,or from chinese top manufacturer such as the seamless steel tube with alloy.Material details as below: First section :16MN(Q345B) Second section:16MN (Q345B) Third section:27 SiMn Forth section:35 CRMO There are mainly two types of kelly bars: 1.Interlocking Kelly Bar 2.Friction Kelly Bar 1) Interlocking kelly bar Interlocking kelly bars are used with pilling rigs for drilling in dense sand,gravel and weak to strong rock . The interlocking kelly bars can be fully locked by mechanical locking system on each section.Kelly bars can be equipped with specially designed springs or pressure plates for shock absorbing purpose.

2) Friction kelly bar Friction Kelly bar is another type kelly of bar ,which the external key is composed of 3 or 6 wear -resistant strip without pressunrizing point .This kelly bar can form pressure force when the kelly bar is rotary.can produce peripheral force and the rotary passing down the pressure force,can produce the friction force.This kelly bar has the advantage of opeerating sample .drilling deep ,but with less pressure transmission.So this kelly bar is suitable for the soft and silt layer.
