Friction Kelly Bar -  components in the execution of boreholes with hydraulic rotary drilling rigs

Kelly bar is the 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 matched with drilling rigs of Bauer, Hitachi, Nissha, Sumitomo, Soilmec, Casagrande, MAT, IMT, etc.

Advantages of friction Kelly Bar

- Telescopic Kelly bar with round cross-section, hard and high abrasion resistance, limit the stuck during drilling, such as drilling equipment used to square cross section as Kelly ED4000, ED5500
- High standard steel pipes materials are imported directly from Korea.
- Length of Kelly Bar  can be adjusted according to the specific requirements of customers.
- Diameter of Kelly is diversified and consistent with the drill heads.

Friction Kelly Bars are used with piling rigs for drilling in silt, clay and less dense sand and gravel.
