IMT Drilling Rig Kelly Bar

After studying IMT drilling rig kelly bars, we have added our own production experiences and customer operating practices and applied them to producing IMT drilling rig kelly bars. We have improved their specifications and made them stronger, lower weight, a higher abrasion resistance, and a higher reliability.

We supply kelly drive stubs for customers to choose from in the following options: 130 x 130, 150 x 150, and 200 x 200. Other types can also be customized.

We provide a damping system consisting of the damping spring and rubber ring in order to reduce damage to each impacted element.

Weight is specifically not listed in the data below. For exact details, please contact us.
