The kelly bar is a key part of a drilling machine, and its quality directly affects the performance of the whole machine. Based on the rich manufacturing experience and by absorbing the advanced technology both at home and abroad, we can produce first-class kelly bars which can be compared favorably with the imported ones. Interlocking kelly bars are used with piling rigs for drilling in dense sand, gravel and rock from the weak to the strong. Interlocking kelly bars manufactured by Unimate 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.
