Kelly bar is the key part of a drilling machine, and its quality directly affects the performance of the whole machine. The main purpose of kelly bar is to transfer the torque of rotary drive and crowd pressure of the crowd system to the drilling tool. Kelly bars can be equipped with specially designed springs or pressure plates for shock absorbing purpose.
