Kelly Bars - High-tensile Steel, 2-5 Telescopic Sections For 15-100m Depth Range | 120-480knm Torque Transfer Capacity, Shock Absorbers, Noise-damping System

We are the largest manufacturer and supplier of kelly bars in
Gurgaon, Haryana, India. Kelly bars are key components in the execution of boreholes with hydraulic rotary drilling rigs. They transfer the torque of the rotary drive and the crowd pressure of the crowd system concurrently to the drilling tool. A Kelly bar consists of 2- 5 telescopic tubular sections with a system of drive keys and lock recesses, welded onto their outer surfaces. Standard Kelly bars are fabricated with a total of 6 drive keys on each section. The tubular Kelly sections are manufactured from high-tensile steel to ensure minimum weight at adequate strength. 2 - 5 fold telescopic construction for a depth range from 15 - 100 m torque transfer capacity 120 - 480 kNm interlocking type (as standard for BG rigs) friction kelly (mainly for crane attachment rigs). 6 cams and large wear-resistant guides. spring-type shock absorbers. standardised square kelly drive stub for connecting all types of drilling tools noise-damping system (optional).
